FUNCTIONAL CATHODE MATERIALS FOR Li-ION BATTERIES — PART III: POTENTIAL CATHODE MATERIALS Li_xNi_1-y-zCo_yMn_zO₂ AND LiMn₂O₄

Abstract

This paper briefly reviews physicochemical properties of intercalated transition metal compounds with layered and spinel type structure to correlate their microscopic electronic properties, i.e. the nature of electronic states with the efficiency of the lithium intercalation process that is controlled by the chemical diffusion coefficient of lithium. The data concerning cell voltages and characteristics of discharge for various materials are correlated with the nature of chemical bonding and electronic structures.
