Short answer, not sure. But the end game is to make a lighter battery eg. the Tesla battery weighs about 1000lbs which is close to 400kg. I did a quick US search and couldn't find the inventor so maybe 'trade secret' but I did find something similar. Graphene comes up as usual but it's 100m2/g so whatever it is there's not much of anything in there and graphite worms - yeah, no typo there.
