Here's the closest thing to a datasheet that I can find on the Genfeng Lithium solid state batteries:
- Semi-solid lithium ion cell (ganfenglithium.com) <http://www.ganfenglithium.com/pro3_detail_en/id/181.html> - Semi-solid lithium ion cell (ganfenglithium.com) <http://www.ganfenglithium.com/pro3_detail_en/id/181.html> - <http://www.ganfenglithium.com/pro3_detail_en/id/181.html>Solid state lithium battery module (ganfenglithium.com) <http://www.ganfenglithium.com/pro3_detail_en/id/198.html> There are some real numbers there, even if it doesn't provide what you'd normally find on in a datasheet. There are enough numbers that you can solve for the weight of the battery module and compare the headline stats to common battery chemistries. The two numbers which jumped out at me are the sustained discharge rate (0.3C) and the Wh/kg (210Wh/kg for the battery module). If you try to order one <http://www.ganfenglithium.com/product11_en/typeid/26.html>, you get sent to a contact form. That's probably about right for where they are in the product lifecycle. These are the most detailed publicly-available specs that I've found for a solid-state battery that I've encountered so far. -Luke On Wed, Jan 26, 2022 at 1:12 PM EV List Lackey via EV <[email protected]> wrote: > On 26 Jan 2022 at 7:58, Paul Wujek via EV wrote: > > > https://www.youtube.com/watch?v=QKqpZG-s_ac > > Sorry, I'm not that keen on sitting through a video clip when I can read > something in 1/10 the time, so I found this: > > https://news.metal.com/newscontent/101690892/Here-comes-the-solid-state- > battery-The-lithium-giant-says-it-can-be-mass-produced-and-loaded-at-any- > time/ > <https://news.metal.com/newscontent/101690892/Here-comes-the-solid-state-battery-The-lithium-giant-says-it-can-be-mass-produced-and-loaded-at-any-time/> > > or https://v.gd/S0Z3FF > > The translation from the Chinese isn't great.
