Abstract
Official abstract text for this publication.
The present invention is to provide a cathode active material configured to increase, when used in a lithium battery, the discharge capacity of the lithium battery higher than conventional lithium batteries, and a lithium battery including the cathode active material. Presented is a cathode active material for lithium batteries, wherein the cathode active material is represented by the following composition formula (1) and has a rock salt type crystal structure including formula (1): Li 2 Ni 1-x-y Co x Mn y TiO 4 wherein x and y are real numbers that satisfy x>0, y>0 and x+y<1.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cathode active material for lithium batteries, wherein the cathode active material is represented by the following composition formula (1) and has a rock salt type crystal structure: Li 2 Ni 1-x-y Co x Mn y TiO 4 Composition formula (1): wherein x and y are real numbers that satisfy 0.1<x<0.8, 0.1<y<0.8 and x+y<1. 2. The cathode active material for lithium batteries according to claim 1 , wherein the rock salt type crystal structure is an irregular rock salt type crystal structure. 3. A lithium battery comprising a cathode, an anode and an electrolyte layer disposed between the cathode and the anode, wherein the cathode comprises at least the cathode active material for lithium batteries, which is defined by claim 1 .
