Patent abstract
Electrolytes, lithium ion cells and corresponding methods are provided, for extending the cycle life of fast charging lithium ion batteries. The electrolytes are based on fluoroethylene carbonate (FEC) and/or vinylene carbonate (VC) as the cyclic carbonate component, and possibly on ethyl acetate (EA) and/or ethyl methyl carbonate (EMC) as the linear component. Proposed electrolytes extend the cycle life by factors of two or more, as indicated by several complementary measurements.
