Lithium iron phosphate batteries are extreme safe though?
- samatman 5y agoRelatively speaking, absolutely. Both those and other formulations (mostly lithium cobalt oxide) have ionic lithium, hence, lithium ion. This uses metallic lithium, which again, reacts explosively in the presence of water. The danger of 'standard' lithium ion chemistries is, as a sibling comment mentions, that the electrolyte and anode are flammable. LiFePO is much more stable and unlikely to burn, relative to lithium cobalt oxide: but neither of them will straight-up explode if a naive fire department sprays water on them to try and put a fire out.
- Robotbeat 5y agoI don’t think that’s the huge risk you think it is. The cells are encapsulated and the lithium metal (in very thin sheets between non-flammable solid state electrolyte) is not exposed. Naive fire departments spraying water on an oil gasoline fire would cause much worse damage.
