SpectraPower's Heritage​

​PolyStor

​In 1993 President Clinton announced that PolyStor was awarded a DARPA/DSO TRP contract to commercialize its aerogel supercap invented at LLNL. PolyStor spun-off PowerStor, acquired by Cooper/Bussmann (now Eaton) who manufactures in high volumes (www.bussmann.com) and sells through Digi-Key, etc.

With installed capacity of 6M cells/yr, starting in 1996, PolyStor is the only U.S. company to have manufactured and shipped >1M lithium-ion batteries from a U.S. manufacturing plant.

Over an 8 year period, PolyStor developed and produced every major form factor and technology, including High Power automotive cells for DOE’s PNGV program with Ford, GM, Chrysler and AeroVironment.

SpectraPower’s founder and CEO, James Kaschmitter founded/co-founded the following companies in energy storage: 

  • PolyStor Corporation (1993): pioneered li-ion manufacturing in the U.S

  • PowerStor Corp (1997): developed and manufactures carbon aerogel supercapacitor. Sold to Cooper-Bussmann

  • UltraCell Corp (2002):​ working with LLNL, DARPA and U.S. Army CECOM, UltraCell  manufactures the world’s only micro Reformed Methanol Fuel Cell (RFMC) for the U.S. military.​ Sold to Brentronics.

  • SpectraPower (2002/2014): Advanced battery and supercap R&D
