NOVELTY - The utility model relates to the field of storage battery, specifically relates to a fluorinated graphene negative plate, comprising a grid and lead paste set on the two sides of the grid, wherein the grid comprises a pole ear; a frame body and a substrate set in the middle of the frame body for conducting; the lug is connected with the substrate and passes through and extends out of the frame body; the substrate is uniformly distributed with a plurality of through holes distributed in square array shape; the extending direction of the tab is defined as longitudinal direction; the direction vertical to the longitudinal direction is transverse; the base plate located between the adjacent through holes is provided with a plurality of convex parts distributed along the symmetrical axis between the two through holes; each of the convex part is distributed along the longitudinal direction; each of the convex part is protruded out of the surface of the base plate and forms a lateral through hole along the surface direction of the base plate; The lead paste covers the surface of the substrate and is filled in the lateral through hole. The utility model is applied to the production of the cathode plate of the storage battery.
