For what it's worth there are a few of these in development but they are not ready for mass commercialization yet. Actual serious battery companies working on 3D printed solid state batteries that is, with actual real scientists. My interest has been entirely selfish. I want batteries that are lighter and will outlast my tools. I also want everything to have snap on or slide in batteries instead of being sealed in and not user serviceable.

Oh I don't doubt they exist in a lab, but the idea that Donut had production ready ones was very far fetched from the beginning of this.
