Watch the video in the article it goes into that.
They passively cooled they say that via conduction they even took half the passive cooling away
Yes after fast charging at 11C they were able to get back out of it 98% -99% of what they put in they lost 2% to heat and other kinetics.
The whole point of independent testing is to well test it. Show what a packaged device or cell can do on a test rig it’s not rocket science you plug it in establish the conditions and let it rip.
They don’t list the max temp but it was within its operating window or it would’ve failed or at the least shown huge resistive loses and only returned a fraction of what it was charged with.
Not much to mess up in a solid state cell it’s either nanoglass, ceramics or polymer as the separators/”electrolyte” the anode and cathode in Li is already solids even in liquid electrolyte cells.
Thanks. I did not watch the video so I plead ignorance.
To be honest, I can read much faster then a video voice talks, so I prefer text. Unless the “gizmo” or process being explained is convoluted or difficult to explain
