A net special for battery electrode and method for making same and dedicated device

Abstract

The invention discloses a battery electrode special web and its preparing method and special preparing device, and its main technical project: using a working platform connected with metal plate feeding mechanism, the end of the working platform is a right-angled or obtuse-angled base, there is a special device composed of machine tool head and able to drive the mould to swing right and left and shake up and down on top side of the base, there is a special mould fixed on the special device, which can produce metal web plate with meshes and battery electrode special web connected with the metal web plate. The special web is carved of metal plate, therefore it has no contact resistance but high mechanical strength, uneasy to deform, thus able to largely reduce internal consumption of battery, raise effective output power of the battery and beneficial to assurance for battery product quality.

Description

technical field [0001] The invention belongs to the technical field of screens, and in particular relates to a special screen used as a battery electrode, a preparation method thereof, and special equipment for preparing the screen. Background technique [0002] At present, the special wire mesh used for battery electrodes is mostly welding electrode connecting wires on the woven mesh, that is, the mesh is used as one electrode of the battery, and the connecting wire is connected to the other electrode of the battery. Since the electrode wire mesh is welded or connected by other mechanical methods, when the current passes, there is a large contact resistance between the two, which increases the internal consumption of the battery and reduces the effective output power. There is also a special wire mesh for battery electrodes, its structure is that the mesh is woven with metal wires, the connecting wire is a part of the metal wire in the mesh, and the ...

AI Technical Summary

Problems solved by technology

This kind of electrode wire mesh is welded or connected by other mechanical means between the connecting wire and the mesh, so when the current passes, there is a large contact resistance between the two, which increases the internal consumption of the battery and reduces the effective output power.

There is also a special wire mesh for battery electrodes, its structure is that the mesh is woven with metal wires, the connecting wire is a part of the metal wire in the mesh, and the mesh and the connecting wire form an integrated structure, but because the mesh as the electrode part is It is woven, and the meshes are only formed by friction. During the battery production process, it is inevitable to pull the mesh as the electrode, and the mesh is easily deformed, thus affecting the product quality of the battery.
