Abstract

The invention relates to an accumulator plate, which comprises an accumulator plate, wherein the both sides of the accumulator plate are coated with an active ingredient layer; and an electrode film layer is arranged on the outer side of each active layer. In the invention, two-side pasting technology is adopted and a piece of electrode paper is pressed on the surface of the plate. In a pasting process, paste is uniformly coated on the front and back surfaces of the plate by adopting the two-side pasting technology, so a plate is uniformly stressed; and after the plate is solidified, the plate obtains more active ingredients and the plate is difficult to deform in the solidification process. The electrode film pressed on the surface of the plate can effectively prevent the stripping of the active ingredients, so the cycle service life of the accumulator is prolonged; and meanwhile, the accumulator plate provided by the invention effectively increases the active ingredients on the plate surface, makes the active ingredients on the plate firm, overcomes the defect that the plate has a fewer active ingredients and the defect that the active ingredients are easy to fall in the prior art and prolongs the cycle service life of the accumulator.

Description

technical field [0001] The invention relates to a storage battery pole plate. Background technique [0002] Paste-coated battery plates are currently used as battery plates. Single-side paste technology is generally used, and there are few surface active substances. It is easy to cause the plate to bend during formation, and the active material on the cured plate is easy to fall off. , which reduce the capacity and cycle life of the battery. Contents of the invention [0003] The purpose of the present invention is to provide a pole plate with a reasonable structure, which can effectively prevent the bending of the pole plate and the falling off of the active material during formation, and prolong the cycle life of the battery. [0004] The technical solution of the invention is: the invention includes a storage battery grid, both sides of the storage battery grid are coated with an active material layer, and an electrode film is arranged outside the active layer.
