Pouch-type batteries gain attention in defense, robots on thermal runaway management

Pouch-type batteries are drawing renewed interest in defense and robotics as battery companies expand beyond slowing EV demand into sectors such as energy storage. The format offers high energy density and design flexibility but has faced concerns about rapid heat transfer between cells during thermal runaway. With all-solid-state solutions still years away, competition is shifting to external safety materials such as thermal barriers. Demand is also emerging from submarines and robots, though high material costs remain a hurdle for mass adoption.
