Technology - Showcasing Kokam Lithium Polymer Batteries
Kokam have developed an advanced and economically viable grid storage solution using Superior Lithium Polymer Battery (SLPB) technology. The patented SLPB technology is currently in production in the U.S., and has been utilized in numerous applications throughout the world. The proven SLPB cell design increases energy density to as high as 200 Wh/kg in high energy cell configurations. The Kokam SLPB meets all performance standards of the U.S. Advanced Battery Consortium (USABC) and has been commercially sold into multiple applications since 1998.
Kokam recently introduced an advanced Nano 1.0 cell that has increased energy and power densities, 7,000 life cycles at 80% DOD, 10+ years life with outstanding safety and stability characteristics.
Kokam's SLPB has proven its outstanding power, energy density, cycle life and safety. Since its establishment in 1998, Kokam has supplied large format cells ranging from 50Ah to 240Ah.
