EVs do not all share the same battery chemistry. Many have LFP batteries, and these are common for home batteries too. You can go on YouTube and see people drilling into an LFP battery with only a little smoke to show for it.
- giobox 2y agoRight exactly. Any discussion about this topic that doesn’t separate LFP (lithium iron phosphate) based batteries from the wider discussion about lithium ion is missing one of the biggest changes to battery tech in recent years. Not all lithium based batteries share the same fire risks - there are enormous differences now. Increasingly EVs and especially backup batteries use the LFP tech - you can charge it to 100% without harming the battery unlike previous lithium ion batteries, and they don’t really catch fire. This paper even acknowledges LFP is significantly safer, mentioning it once, but doesn’t dive into the significant improvements. Again, many EVs (including brands like Tesla etc) already use LFP packs in many cars, and the usage is only increasing. Tesla’s generation 3 powerwalls (home backup battery) are LFP too, its really taken off for home power storage for very obvious reasons - they don’t really catch fire, and you don’t need to worry about charging to 100% harming the battery over time.
