In 2016, Blue Current imagined the possibility of combining the mechanical elasticity and adhesive capabilities of polymers with the ionic conductivity of glass ceramics to maximize safety, temperature, performance, and scalability. In 2018 the company used this approach to create a fully dry solid- state battery with a high silicon content anode to increase energy density. The company refers to this combination of properties together as a “silicon elastic composite” battery. The materials and processes were co-designed from the outset to be produced with high volume manufacturing equipment.  The company is building its first Megawatt-scale pilot factory in California that will produce sample batteries for industry partner and customer validation.  

INDUSTRY MAP

Most advanced battery technologies suffer from at least one major compromise relating to safety, pressure, temperature and manufacturing scalability.  We see the potential for a new silicon elastic composite battery that’s highly resistant to fire, provides high energy density, remarkable cycle life and room temperature operation.
