COMPOSITE POSITIVE ELECTRODE MATERIAL FOR LITHIUM ION BATTERY AND BATTERY USING THE SAME |
摘要 |
The present invention provides a composite positive electrode material for a lithium ion battery, which is particularly excellent in high-rate discharge characteristics in a battery, and also provides a slurry, positive electrode and battery using the composite positive electrode material. The composite positive electrode material for a lithium ion battery contains: a positive electrode active material (a); a conductive material (b) having a primary particle diameter of 10 to 100 nm and/or a fibrous conductive material (c) having a fiber diameter of 1 nm to 1 µm; and a conductive material (d) having an aspect ratio of 2 to 50, wherein the composite positive electrode material for a lithium ion battery is obtained by mixing the conductive material (d) with a composition containing the positive electrode active material (a), and the conductive material (b) and/or the conductive material (c), the composition obtained by dispersing the positive electrode active material (a), and the conductive material (b) and/or the conductive material (c) in a solvent to a state where the positive electrode active material (a), and the conductive material (b) and/or the conductive material (c) are forcibly dispersed, and then agglutinating the positive electrode active material (a), and the conductive material (b) and/or the conductive material (c) . |
