PROCESS FOR THE PRODUCTION OF LITHIUM-MANGANESE DOUBLE OXIDE FOR LITHIUM ION BATTERIES AND LITHIUM-MANGANESE DOUBLE OXIDE FOR LITHIUM ION BATTERIES MADE BY THE SAME, AND LITHIUM ION BATTERIES COTAINING THE SAME

摘要

The present invention relates to a method for producing a lithium manganese composite oxide for a lithium ion secondary battery, a lithium manganese composite oxide for a lithium ion secondary battery produced by the method, and a lithium ion secondary battery comprising the lithium manganese composite oxide. More particularly, the present invention relates to a spinel-type general formula Li _1+a Mn _2-b-c M _b B _c O _4-d A _d (wherein M represents aluminum and / or magnesium, B is a number satisfying 0 b? 0.1, c is a number satisfying 0 c? 0.02, and d is 0? D? A lithium manganese complex oxide for a lithium ion battery produced by the method, and a lithium ion secondary battery comprising the lithium manganese composite oxide. The lithium manganese composite oxide for lithium ion batteries according to the present invention provides a lithium manganese complex oxide for lithium ion batteries excellent in electrochemical characteristics.
