Abstract

The influences of trace water on electrochemical performances for lithium ion batteries are investigated by adjusting the trace water in the electrolyte. Electrochemical performances and AC impedance spectra are tested after the first process of lithiation. Results indicate that the battery comprehensive electrochemical properties change little when the water content is less than 211.3 ppm in electrolyte, however, the battery capacity attenuates when the water content is more than 211.3 ppm, results that the impedance increases sharply.
