Market Opportunity

Lithium-ion batteries (LiB) are a significant technology in today’s global green energy initiative because of their high energy density, long lifetime, reasonably safe operation and affordable cost. They enable the possibility of various types of electric vehicles, space applications and even our everyday handheld electronics. The operating temperature of LiB must be well controlled, as its performance, health, and safety depends on temperature.

USC Solution

USC researchers have prepared a unique lithium-ion electrolyte  by dissolving lithium salt in ternary co solvent and fluoroester. This electrolyte improves lithium-ion battery performance at extreme temperatures. It improves battery performance at a temperature as low as -40 to -60 degree Celsius.

Value Proposition

  • Unique electrolytes developed for lithium-ion batteries, helping them withstand a wide range of temperatures
  • Battery provides at least 79% of room temperature capacity at the temperature of -30°C
  • Battery has better reversible capacity after storage at 55° C. as compared to a battery comprising an electrolyte that is a binary baseline formulation of ethylene carbonate and ethyl methyl carbonate

Applications

  • Everyday battery use for electric vehicles, consumer electronics
  • High-temperature applications
  • Space applications

Stage of Development

  • Available for exclusive and non-exclusive license
