They're saying an energy density of 1000 wh/l, not saying per kg in the headline. Looking it up, the 1000 wh/l seems to be a bit above what a bunch of random internet sources say lithium batteries do on average (300-700 wh/l). So, might be a step change in solid state (compared to their old version) but not sure how it stacks up in the bigger scheme of things. They aren't promising world changing impacts either, just better batteries for wearables and stuff. Will be interesting to see how they commercialize it for sure.
