Problems solved by technology

[0004] For this reason, people have been looking for a material that can replace the foamed metal as the positive electrode of the battery. At present, people try to use a mesh or metal substrate with holes as the skeleton of the electrode. This mesh metal substrate has low cost. , the advantages of light base material and small space occupation, but the production battery technology of the existing mesh metal substrate also has the following disadvantages: 1. Compared with the foamed metal, the surface area of ​​the mesh metal substrate is small, and the made of The electrical conductivity of t

Example Embodiment

[0016] The present invention provides an electrode for a nickel-based battery, which is composed of a hemmed cut-and-drawn mesh and an active material, a conductive material, and an adhesive filled therein, and the active material and the conductive material are fixed to the hemmed by the adhesive. Cut the net 10 on.

[0017] Among them, referring to Figure 2, the hemming cut-and-drawing screen is used to manufacture the positive electrode frame. Its main body is a mesh metal substrate 101. The sides are bent inward to form a flat folded edge 102. The folded edge 102 can be Fold the jagged burrs protruding from the edge of the substrate 101 to the inside. There are several cuts 103 distributed on the substrate 101. The cuts 103 can be stretched into diamond, square, circular or fan-shaped holes as needed. At the same time, the slices around the cuts The material twists as it is pulled and forms the frame of each hole.

[0018] In one embodiment of the present invention, the metal ...

Abstract

The invention relates to an anode of nickel-based battery, which is formed by folded-edge cutting network, stuffed active material, conductive material and adhesive. Wherein, the ratio between active material, conductive material and adhesive is active material at 59-81%, conductive material at 15-28% and adhesive at 1-5%, and auxiliary additive at 3-8%. The conductive skeleton with said cutting network, since its two side edge are inward bended, it has no burr to reduce the short circuit and improve the producing efficiency. And the micro conductive powder in the active material, the conductivity of active material is improved. The invention also provides a relative nickel-based battery.

Description

technical field [0001] The invention relates to a battery, in particular to a nickel-based battery and its positive electrode. Background technique [0002] The battery is made of a battery cell and a battery casing wrapped on its surface through chemical formation and packaging. The battery cell includes positive and negative plates and an insulating diaphragm. The positive plate is made of metal filled with positive active materials, conductive materials and adhesives. substrate made. [0003] The traditional positive plate is made of foamed metal. Although the surface area of ​​the foamed metal is larger, more active materials can be filled, and the performance of the made electrode plate is better, but the cost is relatively high. [0004] For this reason, people have been looking for a material that can replace the foamed metal as the positive electrode of the battery. At present, people try to use a mesh or metal substrate with holes as the skeleton of the electrode. ...
