Solid-state batteries have been “five years away” for more than a decade, but Donut Lab claims they’ve finally cracked it. In this video, we break down the world’s first commercial all-solid-state EV battery, promising ultra-fast charging, extreme safety, massive cycle life, and higher energy density than today’s lithium-ion cells. We analyze Donut Lab’s claims from an engineering perspective, explain how batteries actually work, explore why solid-state batteries are so difficult to build, and dig into the real-world data, and what this technology could actually mean for the future of electric vehicles and energy storage.
