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.

The battery industry is moving toward a division of labour similar to semiconductors, with Western companies focusing on next-generation chemistry design and intellectual property while Asian manufacturers handle mass production, industry officials say. The shift reflects limits on building and running gigafactories, weaker manufacturing competitiveness in Europe and the United States, and U.S. rules requiring the exclusion of certain China-linked supply chains. A wider range of battery chemistries and growing small-lot demand are also accelerating outsourcing.
