NOVELTY - This utility new type claims a one positive pole piece, comprise current collector layer and a adhesive, electric conduction agent and positive electrode active substance of the anode material layer, an anode material layer coated on the current collector layer, a current collector layer uniform set with friction surface or friction strip-shaped concave point, further comprise a graphene is helpful to increase the anode material layer conductivity, graphene is attached to the positive electrode material layer. Because the graphene material resistivity is small, is attached to the positive electrode material layer, which can greatly increase the anode material layer of conductivity and lithium ion battery prepared with the positive pole piece, it can increase valid lithium ion battery charging and discharging multiplying power circulation service life and property.
