Blue Current is a battery technology company focused on commercializing silicon solid-state batteries that eliminate flammable liquid electrolytes. Its platform pairs earth-abundant silicon and elastic polymer anodes with fully dry electrolytes, yielding improved energy density, faster charge rates, inherent safety, and operation at low pressures. The design can be manufactured on existing lithium-ion battery equipment, positioning the product for cost-effective, domestic scale-up across electric mobility and stationary storage markets. After more than a decade of research and development, the company operates from a headquarters and pilot line facility in Hayward, California. With safety as a guiding principle, Blue Current’s batteries aim to reduce fire risk while extending cycle life and charging performance. The newly raised capital moves the firm into a full commercialization phase, enabling multiple high-value use cases across energy-reliant industries.
