A lithium ion battery that has a spinel cathode and a nonaqueous electrolyte comprising a fluorinated acyclic carboxylic acid ester and/or a fluorinated acyclic carbonate solvent is described. The lithium ion battery operates at a high voltage (i.e. up to about 5 V) and has improved cycling performance at high temperature.
