ABSTRACT:
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.
