TLDR: it's a solid-state lithium-metal battery design which is able to stop the growth of lithium dendrites which usually make that design unstable; lithium-metal has higher energy density and sustains currents that could fully charge a car in "10 to 20 minutes". Usual disclaimer: "the flexibility and versatility of our multilayer design makes it potentially compatible with mass production procedures in the battery industry. Scaling it up to the commercial battery won’t be easy and there are still some practical challenges, but we believe they will be overcome.”
