I drove a nail through it. Lit its electrolyte on fire. Cut one in half with a pair of scissors. Nothing happened.

I flew to Taiwan and spent 2 days inside ProLogium - the company that has been quietly building solid-state batteries for 20 years, and is now shipping cells at giga-watt-hour scale that hit 360 watt-hours per kilogram on a third-party verified test. We weighed it. We tested it. We tortured it.

This is the deepest solid-state battery video I've ever made. We break down the 4 problems every solid-state contender has to solve - safety, conductivity, pressure, and scale - and how ProLogium claims to have solved all 4 at once, with cells in production today.
