摘要： An electrochemical energy storage device comprising an electrode assembly, an electrolyte, a packing shell and an adhesive material located between the electrode assembly and the packing shell. The adhesive material comprises an adhesive layer and a protective layer. A surface of the adhesive layer, arranged on an outer surface of the electrode assembly and far away from the cell, or a surface of the adhesive layer, arranged on an inner surface of the packing shell and close to the electrode assembly, are adhesive surfaces. The protective layer is arranged on the adhesive surface of the adhesive layer. The protective layer is non-cohesive at a normal temperature and pressure, after the protective layer is fully or partially dissolved in the electrolyte, the adhesive surface of the adhesive layer is exposed to bond the electrode assembly with the packing shell, and the protective layer contains a substance to bear an electric charge.

摘要： The present disclosure provides a method for removing a coating layer of an electrode plate, an electrode plate comprises a current collector and a coating layer coated on each of at least one surface of the current collector, the method for removing the coating layer of the electrode plate comprises steps of: (I) fixing a region where the coating layer will be removed of the electrode plate by vacuum adsorption from a surface of the current collector opposite to the surface of the current collector on which the region where the coating layer will be removed is present; (II) emitting a laser beam on the coating layer within the region where the coating layer will be removed from a side of the surface of the current collector on which the region where the coating layer will be removed is present, so as to remove the coating layer of the electrode plate within the region where the coating layer will be removed and in turn expose the current collector of the electrode plate corresponding to the region where the coating layer will be removed; and (III) getting rid of a residue of the coating layer generated in the step (II). The region where the coating layer will be removed of the electrode plate is fixed by the vacuum adsorption firstly and then the coating layer within the region where the coating layer will be removed is removed by the laser beam, because the electrode plate is fixed, it can avoid a deformation of the electrode plate during laser removing due to a stress generated in the coating layer which is heated by the laser beam and a residual stress released by the removed coating layer.

摘要： The present disclosure provides a method for removing a coating layer of an electrode plate, an electrode plate comprises a current collector and a coating layer coated on each of at least one surface of the current collector, the method for removing the coating layer of the electrode plate comprises steps of: (I) wetting the coating layer of the electrode plate within the region where the coating layer will be removed by using a solvent; (II) emitting a laser beam on the coating layer of the electrode plate within the region where the coating layer will be removed to make the solvent which wets the coating layer of the electrode plate within the region where the coating layer will be removed vaporized, so as to remove the coating layer of the electrode plate within the region where the coating layer will be removed and in turn expose the current collector of the electrode plate corresponding to the region where the coating layer will be removed; and (III) getting rid of a residue of the coating layer generated in the step (II). The coating layer of the electrode plate within the region where the coating layer will be removed is wetted in advance by using the solvent, after the laser beam is emitted on the wetted electrode plate, the solvent existing in the electrode plate absorbs the energy of the laser beam so as to be instantaneously vaporized, thereby generating a strong transient pressure, the particles of the coating layer are peeled off from the current collector under the action of the strong pressure, so as to remove the particles of the coating layer, so that it will not damage the electrode plate, thereby avoiding the deformation of the electrode plate.
