Title: LITHIUM-MANGANESE BASED COMPOUND OXIDE AND METHOD FOR MANUFACTURING SAME, AND CATHODE MATERIAL USING SAID LITHIUM-MANGANESE BASED COMPOUND OXIDE, CATHODE, AND LITHIUM ION SECONDARY CELL
Abstract:
A lithium-manganese based compound oxide characterized by containing a lithium-iron-manganese based compound oxide represented by the compositional formula Li1+x–w(FeyNizMn1–y–z)1–xO2- δ (0 < x < 1/3, 0 ≤ w < 0.8, 0 < y < 1, 0 < z < 0.5, y + z < 1, 0 ≤ δ < 0.5), at least in a charged state of a lithium ion cell using this as a cathode active material, at least a portion of the iron being pentavalent.
