VW-backed QuantumScape says its solid-state batteries will enable EVs to travel farther and charge faster


After nearly a decade in operation, QuantumScape, a San Jose-based startup backed by Volkswagen and Bill Gates, is finally breaking its silence. In a virtual “battery day” event for investors, the recently public company announced that its “solid state” batteries for electric vehicles will charge faster, hold more power, and last longer than traditional EV batteries.

But these batteries can be slow to charge, can freeze up in subzero temperatures, and contain flammable material that can be hazardous in the event of a crash.

QuantumScape claims to have developed a…
