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.
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.
SILICON ELASTIC COMPOSITE APPROACH
100% dry multi-layer cells passed nail, crush and ARC testing by an independent test lab
Cycling over 1000 times at room temperature with over 80% capacity retention
Operate at pressures below 1 MPa enabling improved system level energy density
Materials and processes are co-designed to work with high volume manufacturing equipment
“The proposed work is scientifically meritorious and revolutionary.”
