Solid State Battery Progress

Thu Jul 30, 2020 10:32 am

Saw an article today discussing the progress on solid state batteries...both Toyota, who is working with Panasonic, and Samsung are saying that they expect to have them ready for limited production by 2025. Samsung claims nearly double the energy density. Toyota claims 10% degradation after 30-years. Now, if they can combine those two features, longevity and increased energy density, the end of the decade could be a major game changer. Here's hoping. I'm open to other solutions, maybe a breakthrough in sourcing hydrogen, but that may be longer still. I think that it's going to take a lot of excess green energy to make that a viable solution for scaled used.

Dyson, who stopped their car development program, still has a bunch of research on ss batteries that they'd like to license. Combine all of the features, and who knows...could be good.
