Abstract

The effects of surface coating on electrode properties of LiMn 2O 4 in a sulfide solid electrolyte were investigated. The surface coating with LiNbO 3 reduced the electrode resistance by two orders of magnitude. Changes in the electrode properties were very similar to those observed for the corresponding LiCoO 2 electrodes, which strongly suggest that the space-charge layer formed at the high-voltage cathode/sulfide electrolyte interface is rate-determining and must be controlled to improve the rate capability.
