Bulk and Surface Modification of LiMn1.5Ni0.5O4 as 4.7-volt Positive Electrode Material for Li-ion Batteries

Résumé

Lithium-insertion compounds with the spinel structure become active element of a new generation of Li-ion batteries, namely the 4.7-V positive electrodes that improve the technologies of energy storage and electric transportation. The compound considered here is the bulk and surface modified LiMn1.5Ni0.5O4 (LMN) spinel. We report the structural and electrochemical features of Cr-doped LMN phase and the LiFePO4-coated LMN structure. Emphasis is placed on the control of physical properties that is needed to guarantee the reliability and the optimum electrochemical performance of these materials.
