All solid state battery

Thin-film all-solid-state batteries that form via high-temperature oxidizing-atmosphere heating unlock flexible, safer power.

What it is

The method heats a substrate in an oxidizing atmosphere to fabricate thin-film all-solid-state batteries with solid electrodes and electrolytes layered on a substrate. This matters because thin-film construction targets high power-density and lightweight form factors compared to bulky liquid-electrolyte cells. Previously, building these specific thin-film solid-state stacks required licensing from the patent holder to use the defined process steps and structure.

What you could build

Launch flexible wearable and IoT power modules using thin-film all-solid-state battery stacks without liquid-electrolyte safety constraints.
