Abstract

LiMn2O4 is an attractive 4 V positive material in lithium rechargeable batteries owing to its favourbale electrochemical characteristics besides its economic and environmental advantages. However, problems of limited cyclability, especiallyat elevated temperatures, have limited the uitlity and commercialization of this cathdoe material. Stabilization of the LiMn2O4 spinel structure has been sought to be ralzied by doping the spinel with suitable cations. In this paper, the results of an exploratory research on the cpacity and cyclability of LiMn2o4 cathodes simultaneously doped with Cr3+ and Mg2+ arereported.
