Abstract
The electrochemical behavior of graphite electrodes cycled galvanostat ically versus Li metal in electrolyte solutions containing LiPF6, LiC( SO2CF3)(2), and LiN(SO2C2F5)(2) in ethyl and methyl alkyl carbonates w as studied. The solvents include ethyl methyl, ethyl propyl, methyl pr opyl, isopropyl methyl, and isopropyl ethyl carbonates. The use of asy mmetric, aliphatic alkyl methyl carbonates is shown to be essential to achieve both high capacity and long cycle life with graphite electrod es in Li-ion batteries.
