@bajax @tard @p @fluffy I think solid state batteries have much promise but there is the issue of adequate ion mobility in a solid material. That said what I've read about these batteries is more rumor than actual test data so I haven't a lot of concrete data upon which to base an opinion but I will note that most commercial solid state batteries aren't completely solid and are some sort of hybrid designs because of the ion mobility in solids issue. That said, I am hoping something positive develops, I personally would love an electric car as a primary city driver since the majority of my trips are under 100 miles in a day, but lithium fires dissuades me. But as grid storage I don't think conventional batteries will ever scale sufficiently. Redox flow batteries I believe are about the only chemical battery technology with enough scalability to be useful at grid levels, but thus far they rely on vanadium and vanadium although about as abundant in the Earth's crust as copper, rarely exists in concentrated form and thus is expensive to extract and most comes from China, Russia, South Africa.
