Abstract

Electrolytes containing ethylene carbonate and lithium hexafluorophosphate are the industry standard for commercial lithium-ion batteries. At elevated temperatures or during extended storage, this electrolyte undergoes a series of decomposition reactions, which are autocatalytic. Aging experiments were conducted at temperatures in excess of 80°C to accelerate electrolyte decomposition. The thermal decomposition products include oligo ethylene oxides, alkyl fluorides, and fluorphosphates. The influence of electrode materials on the thermal decomposition reactions was also investigated. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
