▎ 摘　　要

NOVELTY - Positive electrode plate includes a positive current collector whose surface is divided into a hollow foil region and a coating region. An air foil region is provided with a positive electrode ear. The coating region is provided with a positive electrode active layer. The positive electrode active layer is provided with a positive active material and a conductive agent. The positive active material is gradually reduced from a side close to the positive ear to a side away from the positive ear. Content of the conductive agent is gradually increased from the side close to the positive ear to the side away from the positive ear. USE - Positive electrode plate for use in lithium ion battery (claimed). ADVANTAGE - The safety and cycle life of the lithium ion battery is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the positive electrode sheet. Positive current collector (101) Positive active layer (102) Positive ear (103)
