Blue Current, Inc.

Blue Current is a Hayward, California solid-state battery developer building what it calls a 'silicon-first,' fully dry battery platform. Its Silicon Elastic Composite chemistry ties glass-ceramic electrolyte particles to silicon anode particles with compliant polymers, constraining silicon swelling so high-silicon cells can cycle stably at low pressure without flammable liquids or PFAS. Positioned as a safety-focused, B2B licensing and pilot-manufacturing company, Blue Current targets electric mobility, grid-scale storage, and consumer devices, and closed an $80M+ Series D extension led by Amazon in December 2025.
