Abstract

A lithium-ion battery may include a housing, an anode and a cathode that are disposed in the housing and are in ionically conductive contact with one another, an electrolyte composition that is disposed in the housing and providing an ionically conductive pathway between the anode and the cathode, and a porous separator between the anode and the cathode. The cathode may include a cathode active material which is charged to a potential greater than or equal to 4.35 V versus a Li/Lireference electrode. The electrolyte composition may include a) a non-fluorinated carbonate, b) a fluorinated acyclic carboxylic acid ester, c) one or more lithium glycolatoborate compounds, d) a fluorinated carbonate, and e) an electrolyte salt.
