Battery Grade Diethyl Carbonate (DEC), High Purity
Diethyl carbonate is another important solvent for lithium-ion battery electrolytes. The use of high-quality battery-grade solvents having extremely low water (<10 ppm) and impurity contents are critical for achieving the high electrochemical performance of the lithium-ion batteries.

Caution
This electrolyte solution or lithium salt sample is packaged in fluorinated HDPE/aluminum bottles with moisture strictly controlled (normally less than 20 ppm). The bottle is tightly closed and sealed with an aluminum bag. Please handle it and store it in a glovebox with inert atmosphere or a dry room. Avoid from high-temperature heating or igniting. LIB electrolyte should be stored in a PE or Teflon (PTFE) sample bottle but not a glass bottle.
Lithium electrolyte materials are very sensitive even sealed and stored in an inert atmosphere. We suggest replacing the electrolyte with fresh samples every 6 months.
