Blue Current Inc. is a technology company specializing in solid-state battery development, with a focus on creating safer and more efficient energy storage solutions. Based in Hayward, California, the company was established to transform the battery industry through its innovative silicon-based technology. Their approach centers on developing all-solid-state batteries (ASSBs) that eliminate the need for flammable materials commonly found in traditional lithium-ion batteries. Blue Current’s mission is to enable next-generation applications in electric vehicles, wearable devices, and advanced mobility solutions while reducing costs and improving reliability.
Battery Technology
The company’s flagship innovation is its silicon elastic composite battery technology, which combines mechanical elasticity and adhesive properties of polymers with the ionic conductivity of glass ceramics. This unique composition maximizes safety, temperature performance, and manufacturing scalability. The technology uses high silicon content anodes to achieve superior energy density while maintaining cost-effectiveness through simplified production processes.
Blue Current’s batteries operate without liquid or gel electrolytes, making them inherently safer than conventional alternatives. The design allows for lower operating pressures, which reduces the need for expensive protective packaging. Testing has demonstrated exceptional safety performance, with the batteries showing no thermal runaway or material ejection during nail penetration, crush, and overcharge tests.
The company holds over twenty-five patent families covering materials, integration techniques, and manufacturing processes. Their technology is compatible with existing high-volume manufacturing equipment used in the lithium-ion battery industry, enabling efficient production scaling while maintaining quality standards.
Recent Projects
In November 2024, Blue Current appointed Susan Stone as CEO to guide the company toward commercial production. The company is completing a 22,000-square-foot pilot manufacturing facility in Hayward, California, designed to demonstrate economic scalability using standard lithium-ion manufacturing equipment. In December 2023, Blue Current announced expanded partnerships and additional funding, reinforcing their “silicon-first” approach with elastic composite electrolyte technology.
Investors
Blue Current has attracted significant investment from prominent organizations and individuals. Koch Disruptive Technologies (KDT) and Piedmont Capital have provided substantial financial backing. Additional investors include Umicore, a global materials technology company, Alan Mulally (former CEO of Boeing Commercial Airplanes and Ford Motor Company), and Henry Kravis (co-founder of KKR).
