NANOLYTE HV ELECTROLYTE

NanoLyte HV Electrolyte is for high performance: improving energy density, cycle life, and temperature range of li-ion cells charging to high voltage. NOHMs’ functional ionic liquid forms solid-electrolyte interface (SEI) that protects the high-voltage electrode from reaction with the electrolyte.
