Blue Current, Inc. announced it has raised over $80 million in a Series D extension funding round anchored by Amazon, with participation from Koch Disruptive Technologies, Piedmont Capital, Rusheen Capital Partners, and Allen & Company. The new funding will accelerate commercialization of the company’s silicon solid-state battery platform, which is engineered to deliver enhanced energy density, rapid charge times, inherent safety, and scalability for mobility and stationary storage applications. As part of the round, James Hamilton, Amazon Senior Vice President and Distinguished Engineer, will join Blue Current’s board of directors.
Designed from first principles, Blue Current’s platform employs earth-abundant silicon and elastic polymer anodes paired with fully dry electrolytes across formulations optimized for electric vehicles and stationary energy systems. The technology is compatible with existing lithium-ion battery manufacturing equipment, enabling a cost-effective scale-up. Blue Current’s silicon-based cells operate at low pressure and offer improved thermal stability and reduced fire risk compared with traditional liquid-electrolyte batteries.
“To meet the urgent energy demands of today’s technology-driven world we need a de-risked approach to solid-state battery commercialization that unlocks domestic manufacturing capacity,” said Susan Stone, CEO of Blue Current. “Our technology platform fundamentally addresses the mobility and stationary storage sectors’ unique needs on an accelerated timeline to safely and reliably power the world. This commercialization phase will enable multiple high-value use cases that will allow us to quickly move to a safe and effective commercially available next-generation battery.”
“Our team has dedicated more than a decade of research and development into creating an industry-leading battery that sets our technology apart from other approaches. By prioritizing battery safety as our north star from day one, we came to our silicon-based design, not only drastically reducing fire risk but greatly improving energy density, cycle life, and charging speed,” said Kevin Wujcik, co-founder and Chief Technology Officer at Blue Current. “With KDT’s continued investment and Amazon’s investment, we look forward to entering the next stage of commercialization and overcoming current market limitations to energy storage.”
Blue Current, headquartered in Hayward, California, operates a pilot line facility where it develops and tests its silicon solid-state cells. The company’s platform—free of flammable liquid electrolytes—aims to provide a safer, higher-performing alternative to conventional lithium-ion technology. Blue Current plans to use the Series D extension proceeds to advance its commercialization efforts and meet rising market demand across e-mobility and energy storage sectors.
