I made a point of tracking Solid Energy Systems back when they were young and were just announcing their “break through” battery technology. What’s interesting was that they seemed to go off the radar when they got their investments and initial customers. Hard to find articles and news about them. Recently I found an interview where they talked about that they had been selling batteries to some niche applications with very specific requirements. Now they seem to be coming into the limelight again and have shipped prototype EV battery packs. In fact it seems like several solid or semi solid state battery techs are just about to reach mass market these days. It’s what.. like 10 years ago we saw all these break through articles (and the obligatory complaints about break through articles)?
