How do these things compare to “regular” lithium batteries on fire hazard?
- xhkkffbf 2y agoThe article says that it eliminates the problem. But I find that hard to believe. On the other hand, silicon dioxide is already oxidized so it can't burn more.

- ianburrell 2y agoSolid state batteries replace the flammable liquid electrolyte with nonflammable solid one. It isn't the lithium that is burning. Also, LiFePO4 are already nonflammable lithium batteries. They have lower power density when solid state are supposed to be equal or better to LiPo.

Our work highlights the need for quantitative safety analyses of solid-state batteries. Would be interesting to hear how Samsung claim to have solved dendrite formation in their solid state batteries. > dendrite
- bagels 2y agoThere's still a potential for a short circuit and a rapid release of energy. Whether that release itself is fire, or the energy causes plasmas and fires doesn't really seem to matter much.
- Tade0 2y agoThe liquid electrolyte is where most of the fire hazard happens in a lithium-ion battery, as it's typically based on ethylene carbonate, which is flammable.
