As someone who works in the battery industry I want to applaud them for calling the battery for what it is; semi-solid state. So many dirt bag companies keep throwing the term “solid-state” batteries around for prototypes they’re working on but they dont exist yet, they’re an aspiration. No company has figured this out yep so right now best you get is a semi-solid state that has improvements over existing chemistry but a whole bunch of additional caveats and negatives.
