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.
Improved High Voltage NMC Chemistries
Nickel-manganese-cobalt (NMC) cathode materials are used in li-ion battery for EV. NMC stores 25% more capacity when charged to high voltage. However, today’s electrolytes have limited voltage and temperature stability.
NanoLyte HV Electrolyte extends cycle life and high-voltage stability. 17 Ah pouch cell charged to 4.35 volts improve 45°C cycle lifetime more than 200%.
High Voltage Stability
- Cells containing NOHMs additives demonstrate better capacity retention
- 400% more cycle-lifetime
- Similar power capability
- Similar initial capacity

Improved High-Voltage LCO Chemistry
Lithium-cobalt-oxide (LCO) cathode materials are used in li-ion battery for mobile electronics. LCO stores 33% more capacity when charged to high voltage. However, today’s electrolytes have limited voltage and temperature stability.
NanoLyte HV Electrolyte extends cycle life and high-voltage stability. This demonstrates 200% more lifetime for pouch cells charged to 4.45 volts using NanoLyte HV Electrolyte.
Thermal Stability at High Voltage
- NOHMs electrolyte retains same stability at room temperature and at 45°C.
