Natron’s liquidation shows why the US isn’t ready to make its own batteries

The recent liquidation of sodium-ion battery startup Natron underscores the significant challenges the U.S. faces in establishing a domestic battery manufacturing industry. Despite having $25 million in orders for its Michigan factory, Natron was unable to deliver products without UL certification—a process that can take several months.

This case exemplifies the difficulties startups encounter in scaling battery production without consistent industrial policies and long-term investor commitment, as battery manufacturing typically requires a decade or more to mature. Natron’s struggles are part of a broader pattern of failures among Western battery manufacturers attempting to compete with established Asian supply chains and expertise. The sodium-ion technology, while potentially cheaper due to sodium’s abundance, has been undermined by a lithium price war in
