alt Hacker NewsI don’t want lithium-ion alternatives for better range. Quite the opposite, I’m actually okay having slightly less range if it means my car won’t spontaneously combust. This one apparently improves the safety of lithium-ion batteries too, so it’s great, but I hate when headlines focus on one thing that matters the least.

Do you worry about spontaneous combustion of ICE cars? They are far more likely to burst into flames than EVs.

Modern LFP LiIon (LiFePO4) batteries are pretty damn safe now, and is also the dominant chemistry in new EV batteries and energy storage systems. The fire risk is nothing like what it was, arguably your wish has already been granted.
The Chinese market is mandating this year that EV batteries prevent fire or explosion for a minimum of 2hrs after a cell enters thermal runaway, and LFP is the main driver to achieve it.
