what makes it so? I don't know anything about this subject, I'm really curious now about what the perfect battery would be.
But 10kJ/mol of activation energy is another way of saying less than 100mV of internal loses, and avoiding phase transitions means that your battery won't stop working on that temperature range.
Perhaps a polymer will be invented that can’t be pierced by dendrites. But existing polymers need to be heated for ion transfer efficiency and are combustable.
Technically, QuantumScape also uses an organic liquid catholyte inside the cathode. So it’s not “pure” solid state.
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.
I believe I get the positive intention behind your post, btw - to defend conversation against shallow dismissals - and of course appreciate that. But if you'd please express it in a respectful way in the future, then you'll be contributing to good conversation rather than degrading it further.
No, I actually work in aerospace and know EXACTLY what the fuck I'm speaking of. Do you build satellites? Looking at your history - no you do not. I do. In fact, I'm responsible FOR THE POWER SYSTEMS (that's battery and solar AND any RTG should we ever go that route.)
Sit down.
If you know more than others do, that's great! But please contribute by sharing some of what you know, so the rest of us can learn, rather than putting others down.
