That would be nice, but so far there are no good candidates that have anywhere near the energy density of Li-based cells. As far as I understand it, besides material degradation and overcharge/overdraw, the energy density itself poses a risk. So even if we had that miracle cell chemistry it would be still pose a fire hazard when subjected to mechanical stress. The stored energy has to go somewhere.
- jacquesm 3y agoThat's true, there are some inherent risks that are hard to mitigate. But those are roughly equivalent to say a gasoline fire or something like that. They are not due to handling the stuff or working on it. Though in fairness: working on an ICE car, especially the fuel supply system is not without risk.
