Talk:Thermal battery

Page under construction
Those of us in the geothermal heat pump industry realized that sever important topics were missing from Wikipedia. We have building this Thermal Battery page and related pages to inform the public about the basic thermal energy storage and usage tools now being applied commonly in new construction and extensive retrofits of HVAC systems.

Article incomplete and needs restructuring
This article is profoundly incomplete. Some of the most common "thermal batteries" do not use thermal storage at all, rather they are thermally activated chemical batteries. These are so commonly used that 50% of current 1st page Google search results are this type of thermal battery, NOT a thermal storage battery. Article needs to be totally restructured to reflect this usage frequency. Joema (talk) 11:54, 4 February 2016 (UTC)
 * I can't agree with this more. The US Department of Energy had a program in the past few years that referred to a Thermal Energy Storage device as a thermal battery. As a 'Thermal Battery' has referred to a thermally initiated electrical power source (thermal battery) since WWII, this has caused quite a few points of confusion in the technical community. The former is a benign thermal energy storage technology. The latter is an electrical energy source used primarily in the fusing and armaments fields, initially related to artillary but later nuclear weapon systems, as mentioned in the Molten salt batteries page. Even that page uses the term thermal battery to describe the items. The fact that the DoE chose to use this term despite the Agency's long history working with and managing the US nuclear arsenal is astounding. The information under the article should be moved to the Thermal Energy Storage page, and perhaps reference to the incorrect nomenclature and points of confusion could be added to that. 158.12.37.130 (talk) 16:59, 22 March 2017 (UTC)


 * It's also a bit confused because part of the page (especially the infobox) thinks it's about ground-source heat pumps, and part of the page thinks it's about any device that stores thermal energy for later use, like a locomotive boiler or Thermos flask. Pinkbeast (talk) 19:10, 8 May 2017 (UTC)


 * Yes, agree with all the above. Culturalextreme (talk) 16:44, 24 August 2022 (UTC)

Article should be removed, replaced with a redirect or disambiguation page
There is a historical context here that far predates the problematic use of thermal battery to refer to thermal energy storage, yet alone some specific heat pump application. I propose that the page be replaced with a disambiguation page with links to the appropriate items, Molten-salt battery being the primary historical usage and Thermal energy storage being the newer one, both of which already have well maintained pages. The problem populating and maintaining this one in any useful fashion over the past couple years is evidence enough that links would be better.Nrjank (talk) 19:31, 1 November 2018 (UTC)
 * I agree. It's almost completely uncited and (inasmuch as it attracts edits at all) a magnet for shills for one company or another. Pinkbeast (talk) 05:10, 4 November 2018 (UTC)
 * I will be updating Thermal Batteries soon based on current R&D out of ORNL and MIT. Please see notes in Talk:Thermal_energy_storage. Clemenzi (talk) 19:30, 5 November 2023 (UTC)

"Sand battery" listed at Redirects for discussion
An editor has identified a potential problem with the redirect Sand battery and has thus listed it for discussion. This discussion will occur at Redirects for discussion/Log/2022 July 5 until a consensus is reached, and readers of this page are welcome to contribute to the discussion. 64.229.88.43 (talk) 22:05, 5 July 2022 (UTC)

Could we use Heat Batteries in an another way?
So yesterday was the launch of Artemis-1 space missions rocket the SLS and the Orion... The goal of mission Artemis is to create a base on moon! So on the moon at daytime theres 120°C and at night theres -130°C. I was wondering if we could store the daytime heat and then use it to for heating at night? And at night we could store the cold so we could use it for cooling. 37.76.58.167 (talk) 06:30, 17 November 2022 (UTC)
