About
Sionic Energy licenses a lithium-ion cell design with a 100% silicon anode that battery makers and OEMs can build on their existing production lines.
Called the Rapid Integration Silicon Platform, it replaces graphite entirely and needs no pre-lithiation or cell compression. Sionic rates it at 370 Wh/kg with a charge to 80% in five to ten minutes, and has validated it in 21700 cylindrical, pouch and prismatic formats. Licensees get an IP package, material specifications and on-site technology transfer.
Sionic is headquartered in Rochester, New York. Cornell University scientists founded it in 2011 as NOHMs Technologies, and it spent its first decade developing electrolytes before moving to silicon anodes.
