SINGLE PHASE LITHIUM-DEFICIENT MULTI-COMPONENT TRANSITION METAL OXIDES HAVING A LAYERED CRYSTAL STRUCTURE AND A METHOD OF PRODUCING THE SAME

摘要

PURPOSE: A single phase lithium-deficient lithium multi-component transition metal oxide of layered crystal structure and a manufacturing method thereof are provided to enhance energy density, high-capacity, high stability and long lifetime property. CONSTITUTION: A single phase lithium-deficient lithium multi-component transition metal oxide of layered crystal structure is represented by chemical formula 1. The chemical formula 1 is as follows: Li1-aM11-x-y-zM2xM3yM4zO2. In the chemical formula 1, M1 is transition metal having one or more oxidation number of +3, M2 indicates transition metal having one or more oxidation number of +4, M3 indicates transition metal having one or more oxidation number of +5, M4 indicates one or more elements having oxidation number of +2, and x+2y-z>0, x+y+z<1, 0
