Talk:Silver oxide battery

"Super Silver Oxide"?
Some companies are selling "Super Silver Oxide" batteries. Enquiring minds want to know, is this just marketing hype, or are they actually better than "regular" silver oxide batteries? 71.219.245.63 (talk) 16:32, 31 July 2009 (UTC)

Silver zinc
"silver zinc" is NOT the same chemistry, actually this is a type of secondary battery.

Question: Is this kind of battery rechargeable? I can't find that in this article...
 * AFAIK no. ajdlinux 22:04, 1 April 2007 (UTC)


 * The article now mentions rechargeable silver-zinc batteries made by Zpower. 71.219.245.63 (talk) 15:52, 31 July 2009 (UTC)

"Complete inflammability"
Flammability means the same thing as Inflammability. I believe the article's author meant non-flammability when discussing battery types, as "complete inflammability" is not something one would want to brag about. —Preceding unsigned comment added by 207.2.122.148 (talk) 15:56, 20 March 2008 (UTC)

Silver 1,3 Oxide and Zpower's claims
Zpower claims to use a higher oxidation potential than Ag2O, closer to AgO. See their site (http://www.zpowerbattery.com/).

Temperature
Does anyone know the operational temperature range for Silver Oxide batteries? Magu (talk) 05:27, 26 September 2009 (UTC)

Voltage
Wouldn't it be a good idea to mention the normal open cell voltage?! I think it's 1.55V. —Preceding unsigned comment added by 85.249.223.13 (talk) 20:23, 16 March 2010 (UTC)

Siver-zinc battery section accuracy.
First, this section has the chemical reactions. In fact nearly every reference on the subject states something along the lines, "The reactions within the cell are not fully understood" (this a direct quote from one such source).

Second, the article claims a terminal voltage of 1.55 volts and claims that this is as high as it gets. The silver-zinc battery, unusually has two quoted terminal voltages, 1.86 volts and 1.55 volts. A fully charged battery is 1.86 volts. On discharge, this voltage remains very constant. That is: until somewhere between 20-30% discharged when the terminal voltage suddenly and abruptly falls to 1.55 volts and remains constant until exhaustion. It is believed (but AFAICT unproven) that this is because there are both argentic and argentous oxides in the positive plate and that one is consumed before the other. The battery type was considered for many years to be obsolete but there is considerable evidence that it is being developed once again as a potential (and safer) replacement for Lithium-ion batteries.

The silver cathode plate material of the battery cathode can be charged to the higher oxide potential, and occasionally used as a source of battery discharge power at the beginning of the battery discharge period in the case of a single discharge power source unit. But it is hard to achieve the recharge storage of electrical energy at the higher voltage storage level.WFPM (talk) 23:05, 24 February 2013 (UTC)

The battery can also be constructed in a charged condition for primary electrical power supply purposes (Silver oxide versus reduced zinc). This will provide the maximum primary electrical energy supply capability. It can then be recharged for further mission requirements. It can also be constructed in an uncharged condition (sponge silver versus zinc oxide} and then charged after being activated with electrolyte.WFPM (talk) 16:35, 5 March 2013 (UTC)

Quite apart from the section dealing with 'Silver-zinc' chemistry which should be a separate category (the heading here is 'Silver Oxide') there is the potential confusion arising from use of the terms 'cathode' and 'anode'. In primary battery chemistry (single discharge then discard) the negative electrode will always be called the anode, where oxidation (loss of electrons to a circuit) takes place and the positive electrode will always be called the cathode, where reduction (gain of electrons from a circuit) occurs. However, when describing the chemistry of a secondary battery (rechargeable after discharge), the terms cathode and anode are applied to the negative and positive electrodes respectively when the battery is under charge. The reason for this is in the meaning of the words 'cathode' and 'anode'. Cathode means 'the way down or in'(for electrons); Anode means 'the way up or out'(for electrons) both words originally derived from the Greek. So it is very easy to confuse the average reader without a background in electrochemistry by linking the terms anode with negative or cathode with positive because this is not always the case.

 * There is no convention for rechargeable batteries and the terms 'anode' and 'cathode' should be avoided. Some authorities use the term 'anode' to describe the positive electrode of the cell, but those same authorities also incorrectly call the positive electrode of a primary cell the anode, causing much confusion.  The reality is that from the definitions of 'anode' and 'cathode' that the anode and cathode switch ends between charge and discharge of a secondary cell.


 * I have a remote control that uses a CR2016 button cell. The battery compartment is helpfully labelled 'anode up'.  Although it is possible to install a battery this way, it would be left with no connection to the anode as both contacts would connect to the cathode.

Some proposed changes
The section on sliver zinc has outdated information and cites an article from 2008 that says silver zinc batteries (made by ZPower) are going to go into laptops. Here is the quote from the page, "Long used in specialized applications, it is now being developed for more mainstream markets, for example laptop batteries.[3]" In the time since that article was written, ZPower, which holds over 100 patents on rechargeable silver zinc microbatteries and is the only company in the world able to legally manufacture and sell micro, rechargeable silver-zinc batteries, has instead gone in the direction of developing a rechargeable system for hearing aids. ZPower battery technology is now built-in to hearing aids designed by nearly every major manufacturer. Find the list here: We suggest editing this section to reflect relevant changes in the industry that have occurred since 2008, with a change to the quoted section and its reference that points to laptops, and replacing it with a mention of hearing aids as the example of silver zinc's mainstream market adoption, as this is what is actually happening right now. If the citation from ZPower is too commercial, here is a link to an article from NASA.gov: Thank you for reviewing this requested edit.

 * Thanks for the suggestion; I have added the article from NASA. Altamel (talk) 01:48, 29 April 2017 (UTC)

This may be the best article to include a brief historical note that (platinum plated) Silver/Zinc was the chemistry used in the early batteries developed by Edward O.W. Whitehouse to power the first Trans-Atlantic telegraph.

Title change?
Shouldn't this article be silver oxide battery rather than silver-oxide battery. It is not a battery using silver and oxide. It is a battery where one component is the compound silver oxide. -- Srleffler (talk) 23:23, 7 January 2023 (UTC)
 * Yes, that's correct. I submitted it at WP:RM since it should be an uncontroversial move. VQuakr (talk) 11:17, 8 January 2023 (UTC)
