Wow. Ty.
Thanks for the link. The technology page is quite interesting. 400Wh/kg energy density — by comparison my BattleBorn LiFePO4 100A-h battery (roughly 1200 Wh) weighs ~10kg — so the BattleBorn is about 1/3 the energy density that PureLithium claims.
But the most important reason to be excited about PureLithium is that the CEO is smokin’ hot. Unlike their batteries, of course I hope. :-)
