Talk:Lithium metal battery

Merging
Shouldn't this article be merged with the main article? (Lithium ion battery) --Clickheretologin 15:42, 27 May 2006 (UTC)
 * No. That article is about rechargable batteries only. --Gbleem 22:35, 16 December 2006 (UTC)


 * So, this article would be called disposable lithium batteries. Li ion and Li disposable are lithium batteries.In any case, there are also rechargeable lithium metal batteries --Mac (talk) 11:58, 23 July 2008 (UTC)


 * That's my opinion too (distinct articles for Litium and Li-Ion), but this article includes a lot of information relevant to Li-Ion batteries such as rechargeable Li-Ion chemistry and information about transport safety guidelines that AFAIK apply to Li-Ion batteries (otherwise should be clarified, I never heard of an exploding button cell yet...) Shouldn't some information move to Lithium ion battery? 66.36.135.64 (talk) 06:23, 23 August 2017 (UTC)

"The most common type of lithium cell used in consumer applications uses metallic lithium as anode and manganese dioxide as cathode, with a salt of lithium dissolved in an organic solvent."

Is the salt the electrolyte? --Gbleem 22:28, 16 December 2006 (UTC)

An opinion:
Lithium-containing cells have two main types: primary (i.e. non-rechargeable) and secondary (i.e. rechargeable).

Referring to the photos shown, it is better to label the leftmost photo as anode (i.e. negative) cup and the rightmost photo as cathode (i.e. positive) can. Without indicating the polarity of the cell, it is confusing because the can/cap showing the positive sign on its top (e.g. the photo of CR2032 lithium battery) was placed upside down.

Which is which?
Which battery chemistry is used by my Energizer E2 Photo Lithium Technology 2.5V?
 * Ok I found it in the chart.

Which is the one used for rechargable laptop batteries?
 * "The most common consumer grade battery, about 80% of the lithium battery market." Is the first one on the chart the common laptop battery? I'm guessing the disposable battery sells more units.

--Gbleem 23:05, 16 December 2006 (UTC)

Thionyl chloride
The article states that thionyl chloride is generally not used in batteries sold to consumers. However, I once attempted to dismantle a consumer lithium battery (disposable, size AA 1.5 volts). The battery shorted out, and the electrolyte began to boil. I accidentally inhaled some of the fumes, which were very irritating, similar to hydrochloric acid fumes. If this was not thionyl chloride, what was it (it seems unlikely that an organic solvent would have this property)? --Pyrochem 03:45, 21 April 2007 (UTC)


 * Thionyl chloride cells have 3.6 Volts nominal voltage. A 1.5 Volt battery cannot be a thionyl chloride battery unless it was almost completely discharged and you measured that voltage by coincidence. Better tell us what else was written on the battery or its package or related information sheet. Such as a type designation or number. And be prudent. Thionyl chloride batteries SHALL NOT BE DISMANTLED !!! They are not designed as toys for pyrochemical daredevils. READ THE SAFETY DATA SHEET !!! Thomaszwilling (talk) 22:05, 19 April 2021 (UTC)

Regardless, this information is definitely incorrect (or out of date). As far as I can tell, the standard commercially available lithium PP3 is Lithium Thionyl Chloride. For instance,. lukeuser (talk) 03:10, 9 May 2023 (UTC)

table needed
It would be good to include a table of the most common ones -- or at least include a link to a complete table of such.-69.87.204.2 22:21, 15 May 2007 (UTC)

Quite. This article is about as much use as a chocolate teapot. I've got no idea about lithium batteries, tried to buy a replacement for a TV remote control (bought the wrong one), and wanted to know about the codes (whether they are preceeded by 'CR' or not), because although I know about conventional codes like AA and AAA, I find them quite baffling. Duracell's website was less than useless. I was hoping for a bit of sanity here, but was disappointed. Come on, boffins, how about a TABLE? Iantnm (talk) 16:15, 9 July 2008 (UTC)

shelf life
What are optimum long-term shelf storage conditions? Just above freezing?-69.87.204.2 23:01, 15 May 2007 (UTC)

Any body know what the shelf life of the common Li-Mn battery is? http://www.bodylighting.com/Product_Details.asp?s=google&ProductID=84 Says two years, but I'm skeptical.
 * I know of people, who used lithium b attery 10 years in a computer mothgerboard and there system clock and cmos memory still works. 2 years would rather be a restriction for people, who sell these batteries. --MrBurns (talk) 14:45, 18 August 2009 (UTC)

Chemistries
I'm surmising that CR for Li-MnO2 refers to the CR prefix of watch batteries? If so, this could be made clearer. One might make the connection given the "CR" in the table, but you might not. If you happen to read the caption of the disassembled battery it's "obvious" but that's not the best, sole location for information. And what, praytell, does CR mean? --Belg4mit 16:44, 7 June 2007 (UTC)

I'd also like to know more about this. A guy in a shop told me that the 3V batteries come in different thicknesses, and that I can only use one type for a given device. But he admitted he had no idea why this is.


 * The part number often specifies the diameter and thickness of the cell. A CR2032 is 20mm in diameter and 3.2mm thick. 80.45.129.137 (talk) 10:20, 18 October 2010 (UTC)

This section would benefit from an additional column listing the charging voltage or (-) for primary chemistries. I do not have access to primary sources or I would suggest values.mrt — Preceding unsigned comment added by 24.167.215.216 (talk) 14:24, 30 January 2021 (UTC)

Decameter
Are you really using decimetres cubed as the volume unit in the battery density? Seems pretty random but if it is standard, then whatever. —Preceding unsigned comment added by 204.9.221.126 (talk) 22:28, 5 June 2008 (UTC)

It is decimetres cubed (one tenth of a metre). From what I have found, this appears to be standard for battery power density, although I agree, random. A cubic decimetre is the same as a litre, so I suppose this 'standard' might stem from rechargeable cells which have refillable liquid electrolyte (e.g. car batteries). FYI the symbol for decimetres is 'dm'. 194.169.32.250 (talk) 14:17, 29 July 2008 (UTC)

Lithim metal for anode or cathode?
In this article in English mentions:

Lithium batteries are disposable (primary) batteries that have lithium metal or lithium compounds as an anode.

In other article in Japanese mentions:

Lithium metal is used as cathode. (Translation)

http://ja.wikipedia.org/wiki/%E3%83%AA%E3%83%81%E3%82%A6%E3%83%A0%E9%9B%BB%E6%B1%A0

I believe it should be correct the Japanese article in this point. Could someone confirm which is correct anode or cathode? —Preceding unsigned comment added by 70.137.94.18 (talk) 18:42, 16 January 2009 (UTC)

Lithium battery Vs. Silver-oxide battery Vs. Aluminium battery
Witch one of them is the best, Does anyone know?

Cell or Battery
"Battery" is the collective noun for cells (as it once was for fixed guns). A cell is a single reaction container with an anode and a cathode. A battery is a collection of such, packaged together into a single unit and usually connected in series for higher voltages. With traditional zinc-carbon technology, a 1.5V unit is a cell and 6V, 9V and 12V units are batteries of four, six and eight cells, respectively.

This article seems to use the terms interchangeably. With one exception (the 9V battery) all the pictures are of cells and, therefore, mislabelled.

I understand that language changes and that many people use "battery" to describe both battery and cell without any knowledge of or thought about the meanings of the words but I am disappointed to see an encyclopaedia not even acknowledge the original (and, in my view, correct) meanings. Am I over pedantic?

80.45.129.137 (talk) 10:16, 18 October 2010 (UTC)


 * I would like to second this concern. The word "battery" needs to be changed to "cell" in most places in this article, including the title.  Wikipedia is widely promoted as a "free online encyclopedia", and the purpose of an encyclopedia is to provide accurate information, not colloquial 'folk wisdom.'  Despite the fact that many people incorrectly call cells "batteries", cell is the correct term for devices having only a single reaction chamber.  This article is primarily about lithium cells, not lithium batteries.  Confirmation of the correct usage of the terms "cell" and "battery" may be found in any first-year college physics text, such as Fundamentals of Physics, by Resnick and Halliday.
 * If no one else is interested in correcting this article, I will do it myself, when I find the time. — Preceding unsigned comment added by 74.95.43.249 (talk) 20:23, 2 April 2014 (UTC)
 * I suggest to refer to the Electropedia for this question. Electropedia is the IEC's vocabulary and is accessible for free under https://www.electropedia.org/ . "Cell" is found under "482-01-01" and "battery" under "482-01-04". The meaning of those definitions is that in some simple cases where a battery contains only one cell, an object can be both a cell and a battery. Thomaszwilling (talk) 22:03, 2 June 2021 (UTC)

Creating a Catalogue/Table of battery types and Specifications
How about having an overview of Battery Types with Specifications and Sizes? e.g.: CR2025, 20mm Dia, 2.5mm CR2032, 20mm Dia, 3.2mm
 * Check out Button cell and Battery nomenclature and List of battery sizes. --Wtshymanski (talk) 03:03, 24 November 2010 (UTC)

Combine "Air travel" and "Transportation" sections?
Both of these include reference to airmail restrictions and it seems that they would be better combined. At the least they should be consecutive. Daveemtb (talk) 10:58, 24 July 2012 (UTC)

History?
No mention here of first development, testing, manufacturing, or use. (comment from article feedback) --Lexein (talk) 17:27, 10 September 2012 (UTC)

Secondary Batteries
I noticed several secondary batteries listed in this article. It seems like they belong here rather than in Lithium-ion battery, but the definition of Lithium battery would have to be changed to reflect this. I suggest to draw the line at electrode material and say they are mostly primary. Any insights on how these cells are actually classified in academic and industrial literature would be appreciated. 1wonjae (talk) 22:36, 29 November 2013 (UTC)
 * Agreed. Lithium-ion batteries should be moved to Lithium-ion battery while secondary lithium metal batteries should be moved to Rechargeable lithium metal battery. Article "Lithium battery" should remain reserved for primary lithium metal batteries. Thomaszwilling (talk) 21:52, 5 June 2021 (UTC)

No article on Li-MnO2 battery chemistry
If there was a Li-MnO2 battery chemistry or similar, this article could usefully refer to it. - Rod57 (talk) 12:05, 28 October 2014 (UTC)

Ingestion and choking hazard
In that section, it says "battery voltage has increased;". Should that be connected by a comma replacing the semicolon to the next remark about sizes, or is it totally irrelevant? Peridon (talk) 17:24, 8 August 2015 (UTC)

Rename to "Lithium-metal battery"?
What do people think of renaming/moving this page to "lithium-metal battery"? It would serve as a matching counterpart to "lithium-ion battery", since the two types are distinct. As it is, the current name may be somewhat confusing since both lithium-metal and lithium-ion are a type of lithium battery, despite being very different internally. — Preceding unsigned comment added by TROPtastic (talk • contribs) 19:31, 8 November 2016 (UTC)
 * Not a good idea since the article "lithium metal battery" exists and claims that they are secondary (rechargeable) while this article ("Lithium battery") describes mostly primary (non-rechargeable) lithium batteries. Thomaszwilling (talk) 15:46, 24 April 2021 (UTC)

Temperature characteristics

 * An addition I'd like to see in the tables is their temperature characteristics over Temperature. I know that both Li-Iron-disulfide and the Li-coin batteries perform exceptionally well in subzero temperatures (better than Alkaline equivalents anyway).   I use them for game cameras and outdoor thermometers here in Michigan. --2600:6C48:7006:200:D84D:5A80:173:901D (talk) 22:39, 26 October 2017 (UTC)

Confusion
The article starts: "Lithium batteries are primary batteries that have lithium as an anode". Later we have: "Mistreatment during charging or discharging can cause outgassing of some of their contents, which can cause explosions or fire". This clearly refers to secondary batteries. Can we please have consistency in what this article is describing? Mock wurzel soup (talk) 20:26, 17 September 2018 (UTC)

Dubious
From the article:

The above quote is followed by four references (one of which is broken) supporting the statistic for each of the mentioned countries. The Japan statistic is dated to 2010. The European one to 2013 and the Swiss one to 2012. Quite apart from the failure to compare like years with like years, the statistics are hopelessly out of date. The sentence containing, "... 0.5% of all battery sales including secondary types are lithium primaries." is wrong on a fundamental point. Batteries are either primary or secondary. They cannot be both. TheVicarsCat (talk) 17:23, 18 December 2018 (UTC)
 * Any battery can be a primary battery...once. Here's a bag containing all the primary and secondary batteries sold. In that bag, 0.5% are lithium primary batteries. Do you expect huge year-by-year shifts in the composition of battery sales?  We're lucky we've got refs within a couple of years of each other.  Seems OK to me. --Wtshymanski (talk) 20:37, 18 December 2018 (UTC)

Removal of unsourced statement and moved here
This was at the bottom of the chemistries section. It's been there at least since 2009. Unsourced and what does it apply to? Removed from article.
 * The liquid organic electrolyte is a solution of an ion-forming inorganic lithium compound in a mixture of a high-permittivity solvent (propylene carbonate) and a low-viscosity solvent (dimethoxyethane).

Requested merge 15 Feb 2021
I propose to merge the recently created Lithium metal battery article into Lithium battery. Although this article appears to discuss primary cells only, there are also instances where rechargeable lithium metal cells are mentioned. In the very first sentence of the lead it is stated "These types of batteries are also referred to as lithium-metal batteries" so it is confusing to have two separate articles, lets just discuss primary and lithium-metal secondary cells in the same article. Given the small size of Lithium metal battery it can be easily incorporated into a new section on rechargeable varieties. Polyamorph (talk) 09:57, 15 February 2021 (UTC)
 * Support merge - Polymorph's rationale seems spot on. Makes more sense to keep the similar information on the same page.  Onel 5969  TT me 14:02, 15 February 2021 (UTC)
 * Opose - the article now at lithium metal battery should be retitled, perhaps lithium metal rechargeable battery, to distinguish it from the primary type. The rechargeable ones are in the minority. --Wtshymanski (talk) 21:42, 15 February 2021 (UTC)
 * I don't see why any reason why distinguishing the two types cannot be achieved by simply including a section in this article on these minority rechargeable types. Polyamorph (talk) 06:56, 16 February 2021 (UTC)
 * Oppose - It is hazardous to merge an article on rechargeable batteries into an article on non-rechargeable ones. Simply because it is important to distinguish between them. Recharging non-rechargeable lithium batteries is a considerable hazard and can be fatal. People need to be educated to mind the difference. Alternatively, it would be better to 1. create a disambiguation page for lithium batteries, 2. Disambiguate on the first level between rechargeable and non-rechargeable ones, 3. Disambiguate on the second level between rechargeable lithium metal batteries, rechargeable lithium ion batteries, and non-rechargeable lithium metal batteries. There may be non-rechargeable lithium ion batteries but these are really very special and I know only one company bringing them to very few niche markets. So better disregard them. So the resulting three articles should be: 1. lithium metal battery(non-rechargeable), 2. lithium metal battery(rechargeable), and 3. lithium ion battery(rechargeable). Each of them preceded by a link to the disambiguation page. And obviously, the article named just lithium battery could only remain if it becomes the disambiguation page. Thomaszwilling (talk) 22:37, 19 April 2021 (UTC)
 * Undecided - Since the batteries are distinctly different, it seems to make sense to have separate articles. However, the casual/uninformed reader must reach the third paragraph of this article before realizing the difference, especially if they don't know significance of "primary battery".  The text should be improved to put the distinction early and prominent.  Also this article states that "Lithium batteries are widely used in portable consumer electronic devices, and in electric vehicles ranging from full sized vehicles..." which is clearly wrong and evidences the common mistake.  I may have edited that by the time you read this.  Leotohill (talk) 20:54, 21 April 2021 (UTC)
 * I agree. The articles cannot remain as they are. The disambiguation that I proposed will require a lot of work. I am probably going to start by creating new categories for lithium batteries, lithium metal batteries, and non-rechargeable batteries in order to create equivalents for existing categories 'lithium ion batteries' and 'rechargeable batteries', as well as a supercategory for them. This supercategory will have to be a subcategory of 'Category:Battery (electricity)'. Unfortunately, there will be an overlap of these new categories with articles such as 'List of battery types'.Thomaszwilling (talk) 22:36, 21 April 2021 (UTC)
 * Furthermore, this article discusses air travel considerations, but does that really apply to lithium primary batteries? I think this is another example of confusion between the types. (edit:actually, not.) What a mess - but also a good opportunity for improvement.   We have "Lithium battery"  Lithium metal battery, Lithium ion battery and also Solid state battery which has a lot to say about lithium.  Would there be a way to rename and reorganize all of these to make things clearer?  Are these the common industry or marketplace terms?  "Lithium metal battery" seems particularly strange, since it is redundant - lithium is a metal. If these are the names commonly used then I guess we have to live with them, but are they? Leotohill (talk) 02:42, 22 April 2021 (UTC)
 * Here's an update from my research. If you are knowledgeable on and/or working on Lithium battery article, chime in here if you can save me any work. 
 * It's clear that the two principle categories are "Lithium Metal battery" and "Lithium Ion battery". This is the categorization used by industry and international standards.  If there is to be an article titled simply "lithium battery", it should either be a fairly short disambiguation-style article, or one single large article that covers everything.  Note also that "lithium metal battery" covers two subcategories, primary and secondary.  Lithium solid state batteries would be in the latter category.
 * What's proper WP procedure for making a change of this magnitude (retitling multiple articles, reorganizing their content)? I don't want to undertake what will be hours of effort only to be left unsupported and rejected and dejected.
 * Here's one of multiple sources that indicates that "lithium metal" vs "lithium ion" is the proper categorization: []. Note the references to UN 3480, UN 3090, etc.  Leotohill (talk) 20:10, 22 April 2021 (UTC)
 * Hi Leotohill. I'm doing now what maybe I shouldn't be doing. I edit your last edit by removing spaces after the triple colons, adding a colon to your last double colons and removing the line breaks between your last entry and your signature. Forgive me for all that. And yes. I would call me knowledgable in lithium batteries. The problem is that there is no one and only terminology. It always depends on the context. For instance, as you correctly say, lithium metal batteries and lithium ion batteries are the two categories of lithium batteries - in the context of Dangerous Goods Regulations (DGR), as reflected by the IATA DGR for air transport. But: The DGR do not distinguish between rechargeable and non-rechargeable - apart from where they go into the very details of differences between these two categories. The consequence is that disambiguation will really be a tough job for this subject. How can it be done in WP? What is the proper procedure? I am not the big expert in WP procedures but my feeling is that someone has to do it in his own namespace and hope that the articles remain stable while he is trying to find the new structure of the lithium battery articles - and that he can give access to his namespace to others who are willing to help him to find a better structure.
 * By the way, another disambiguation is necessary: Between air travel and air transport. Travel refers to passengers and their baggage, while transport refers to goods or products (such as pallets full of batteries or power tools with batteries inside) which can in principle be transported both on passenger aircraft and on cargo only aircraft. The regulations are quite different for these two categories. Thomaszwilling (talk) 22:11, 22 April 2021 (UTC)
 * That's fine with the formatting corrections, thanks. While I can't find any other sources that make the distinction that the DGR makes (except batteryuniversity.org, which comes close), I can't find any source at all that does what WP is now doing, which is Lithium vs Lithium ion vs Lithium metal. It seems rather arbitrary that WP has decided that "Lithium" means "non-rechargeable with a Lithium metal anode".  Can you find any support for that? If there's no good precedent, I'm now leaning toward supporting Polyamorph's suggestion to merge.  Leotohill (talk) 04:18, 23 April 2021 (UTC)
 * Please have a look at the first sentence of each article:
 * Lithium battery: Lithium batteries are primary batteries that have metallic lithium as an anode.
 * Lithium metal battery: Lithium metal batteries are secondary (rechargeable) batteries that have metallic lithium as a negative electrode...
 * Both of them are wrong. What is correct is that a lithium battery can either be rechargeable (=secondary) or non-rechargeable (=primary). If it is rechargeable then it is most likely to be a lithium ion battery, but rechargeable lithium metal batteries have also been developed and might be found in some market niches. If it is non-rechargeable then it is most likely to be a lithium metal battery, but non-rechargeable lithium ion batteries have also been developed and might be found in some market niches. Now, if you merge those two articles then you can only increase the chaos. If you really want to learn more about lithium batteries then it will be necessary to read the book of David Linden: url=https://www.amazon.com/Handbook-Batteries-David-Linden/dp/0071359788 Thomaszwilling (talk) 22:52, 23 April 2021 (UTC)

Canadian inventions?
Can someone explain why is Canadian Inventions among the categories? There is no mention in the article.589q (talk) 10:33, 26 March 2022 (UTC)

Requested move 23 August 2022

 * The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion. 

The result of the move request was: moved due to apparent precision problems and the metal battery being the primary topic not being apparent. (closed by non-admin page mover) — Ceso femmuin mbolgaig mbung, mellohi! (投稿) 21:20, 30 August 2022 (UTC)

– "Lithium battery" is an ambiguous term that can refer to different types of batteries, but nowadays it most commonly refers to the rechargeable lithium-ion battery. So it makes no sense to have the the non-rechargeable metal battery at the base name. Lithium metal battery currently is little more than a disambiguation page mentioning the two kinds of metal lithium batteries (rechargeable and non-rechargeable). I think it can be deleted and any information can be added to lithium battery if needed. Note that I just created lithium battery (disambiguation), so it still needs some work. Also note that the above merge discussion was actually about merging this article and Rechargeable lithium metal battery. That article was at Lithium metal battery originally and then moved to its current place and then an editor no longer active added the content at Lithium metal battery (see ).

 * Comment: went ahead and merged what was at Lithium metal battery into Lithium battery; seemed uncontroversial. The redirect has the Template:R from merge tag. Rotideypoc41352 (talk · contribs) 20:42, 23 August 2022 (UTC)
 * Thanks for doing that. I agree it is probably uncontroversial. Do you also support moving the dab page to the base name? Vpab15 (talk) 14:36, 25 August 2022 (UTC)
 * Oof, I'm torn. I support the first move (edited 18:20, 26 August 2022 (UTC) to clarify: Lithium battery → Lithium metal battery) . What do you think of having the base name should redirect to Lithium-ion battery? The pageviews for August (views from redirects included) seem to paint the Li ion battery as the predominant one...though, anecdotally, most usage keeps the "ion" in the middle.

 * Of course, if we redirected the base name to Lithium ion battery, we would add the hat to it. Rotideypoc41352 (talk · contribs) 18:20, 26 August 2022 (UTC)
 * I am not sure the page views for Lithium ion battery are big enough compared to the other types of batteries to qualify for primary topic. And as you say, it is usually referred to by its full name. My preference would be to move the dab page. Having said that a primary redirect to the ion battery would be an improvement. Vpab15 (talk) 09:03, 27 August 2022 (UTC)
 * Upon closer examination of the pageviews, Lithium ion battery has less than half of the total linked above. Support both moves as no primary topic exists. Rotideypoc41352 (talk · contribs) 02:20, 30 August 2022 (UTC)
 * Support both moves as proposed, leaving the dab at the base name. -2pou (talk) 16:18, 30 August 2022 (UTC)
