The utility model belongs to the technical field of a lithium ion battery and particularly relates to a positive pole sheet with protruding points on the surface. The positive pole sheet comprises a positive pole current collector and an active material layer coated on the positive pole current collector, protruding points are arranged on the active material layer, and the projection area of the protruding points occupies 5%-50% of the total area of the active material layer. Compared with the prior art, the protruding points are arranged on the surface of the positive pole sheet in a mechanical method so as to enable the positive pole sheet and a negative pole sheet which are attached tightly to generate a gap, the protruding points are pressed flat through expansion of graphite, the expansion of the graphite is accommodated in the generated gap rightly, and outward opening force in a whole battery core is offset. The problem of super thickness and deformation caused by imbalanced internal stress of the battery core can be solved, and deformation rejection rate of batteries is reduced. In addition, a lithium ion battery comprising the positive pole sheet is further disclosed.
