PURPOSE: A pocketed electrode plate is provided to restrain the shrinkage of separator by using excellent adhesive force between separator and insulative film, thereby preventing short circuit and the deformation of electrode. CONSTITUTION: A pocketed electrode plate comprises an electrode plate(100), a separator(10), and an insulative polymer film(30). The electrode plate has coating area and a protrusion(26). The coating area spreads electrode active material. The protrusion is not spread by the electrode active material. The separator is arranged in both sides of the electrode plate in order to expose protrusion. The insulative polymer film is inserted on the opposite side of the separator having a gap with a separator. The insulative polymer film has an adhesive layer for adhering the boundary of the separator. The monomer of the adhesive layer is selected from a group consisting of acryl-based monomer, vinyl-based monomer and styrene monomer. |
