description A positive pole of a lithium ion battery comprises a collector body and a positive pole material coated on and/or filled in the collector body. The positive pole material comprises a positive pole active substance, a conductive agent, a bonding agent and an additive, wherein the additive is poly aliphatic ketone containing no amino and carboxyl. The additive is added in the positive pole providedby the invention, so that the coordination of substances in slurry can be better regulated, and a higher adhesion strength between a positive pole slurry layer and the collector body in a positive plate is guaranteed through properly decreasing the bonding agent dose, and a higher capacity and a favorable circulating performance of a battery can be obtained.
