Latest UpdatesNanoGraf Corporation, which develops materials for next-generation lithium-ion batteries, has begun manufacturing in collaboration with a Japanese company

NanoGraf Corporation (formerly SiNode Systems, Inc.), founded in Illinois, the U.S. in 2018, is a startup company spun out of a team working with Northwestern University and Argonne National Laboratory to develop materials for next-generation lithium-ion batteries. The company was established as a joint venture with JNC Corporation, a Japanese chemical manufacturer, who had invested in its predecessor company SiNode.

The company researches and develops silicon-based anode material additives, which increase the capacity and extend the lifespan of lithium-ion secondary batteries after many charge/discharge cycles. Conventional lithium-ion batteries suffer from capacity losses after about 300 charge/discharge cycles resulting from the destruction of the molecular structure. Using its proprietary technology to wrap silicon particles with graphene (note), the company has succeeded in extending the battery life to 800 charge/discharge cycles.
