alt Hacker NewsSolid state batteries come in several flavours. Most of them don't stop dendrites.
The flavour you want is polymer, single ion conducting solid state with an ion transport activation energy below 10kJ/mol at room temperature and no phase transitions from -40C to 80C.
That is the holy grail of SS batteries.

their benefit boiled down (sic) to flammability, or the lack thereof, right ?
I’m still a novice on the material science behind it, but what is QuantumScape lacking here if anything, and why is it a dealbreaker?
"no phase transitions from -40C to 80C."
Well that's fine for terrestrial use but aerospace needs that range to be expanded a little in both directions, otherwise it won't be much of a holy grail if it won't cover the needs of one of the largest growing industries.

what makes it so? I don't know anything about this subject, I'm really curious now about what the perfect battery would be.
