US sodium-ion battery maker Natron shuts down after 12 years
Natron Energy, a US-based sodium-ion battery startup, has shut down after 12 years due to delays in obtaining UL certification for its Michigan facility.
The company struggled to deliver US$25 million in orders, which led investors to withdraw support.
It had planned a US$1.4 billion factory in North Carolina to create up to 1,000 jobs, but the certification delay left the company facing a cash crunch.
Natron’s assets will be liquidated through an “assignment for the benefit of creditors,” an alternative to traditional bankruptcy.
The startup targeted stationary storage and data center customers, betting on sodium-ion batteries’ lower costs, but a lithium price war in China undercut their potential.
Other Western battery makers, including Oregon-based Powin and Sweden’s Northvolt, have also collapsed due to supply chain challenges and manufacturing difficulties.
These closures highlight the struggle to build battery manufacturing outside Asia, where supply chains and expertise remain dominant.

🧠 Food for thought
Implications, context, and why it matters.
Battery startup failures reveal decade-long pattern despite government support
- Natron’s closure continues a troubling trend of American battery companies failing even after receiving substantial backing, mirroring A123 Systems’ 2012 bankruptcy despite $249 million in Department of Energy funding1.
- The pattern extends beyond individual companies—recent analysis shows multiple U.S. battery gigafactory projects facing delays and cancellations, including KORE Power’s 12GWh project and FREYR’s 34GWh facility2.
- These failures occur despite the Biden administration allocating $3.5 billion to support domestic battery manufacturing, suggesting that funding alone cannot overcome deeper structural challenges3.
- The consistent decade-plus timeline from startup to gigafactory scale often exceeds both business cycles and investor patience, creating a fundamental mismatch between capital requirements and market expectations.
Certification bottlenecks expose regulatory complexity in battery manufacturing
- UL certification requirements create significant barriers, with costs ranging from $15,000 to $20,000 and timelines of 10-12 weeks, delays that can prove fatal for cash-strapped startups4.
- The regulatory landscape includes multiple standards like UL 1642 for individual cells, UL 2054 for battery packs, and UL 1973 for stationary applications, each requiring separate certification processes5.
- This regulatory complexity contrasts sharply with China’s more streamlined approach, where over 1,000 battery manufacturing facilities operate with established quality control systems that have evolved over decades6.
