24M Technologies’ Impervio separator targets EV battery safety with dendrite-deflecting technology

While EV batteries are statistically less prone to fires than their combustion-engine counterparts, the rare incidents that do occur can be catastrophic. Over the last year or so, 24M Technologies has developed an innovative response to this challenge: the Impervio separator, a new battery component designed to prevent internal short circuits, monitor cell health, and isolate faults at the source, writes Peter Donaldson.
