Embodiment Construction

[0010] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] The invention provides a nickel-zinc battery negative electrode base material, such as the attached figure 1 As shown, the nickel-zinc battery negative electrode base material adopts a brass cable-stayed mesh 1 . The brass cable-stayed net 1 contains 65%-75% of copper, 25%-35% of zinc and 0.5%-1.5% of tin. The production process of the brass cable-stayed net 1 is as follows: firstly, it is stamped into a net (thickness and aperture can be adjusted according to requirements), after cutting, folding, and finally rolling.

[0012] The cable-stayed mesh made of brass and electrolytic copper is used as the base material for comparison (made into AA battery); negative electrode active material components: 85% zinc oxide, 10% zinc powder, 3.0% bismuth oxide, 0.1% indium oxide , Potassium fluoride 1.9%, and other substa...

Abstract

The invention discloses a base material of the cathode of a nickel zinc battery. The base material of the cathode of a nickel zinc battery adopts a brass inclined pull net; and the brass inclined pull net comprises 65-75% of copper, 25-25% of zinc and 0.5-1.5% of tin. With the three-dimensional structure, the brass inclined pull net can lead the contact area between the cathode material and the base material to be increased, increases the filling quantity of the active material, and has good current-collecting and electricity-conducting function. The battery has the advantages of stable performance, long cycle life, low cost, simple preparation technology of base material, good electrical conductivity, etc.

Description

technical field [0001] The invention relates to a negative electrode base material of a nickel-zinc battery. Background technique [0002] The traditional negative electrode uses silver current collector as the substrate, and the battery performance is stable, but the cost is high. Using the cable-stayed net made of electrolytic copper as the base material, the performance of the battery is unstable, the low voltage phenomenon of the battery is serious, and the battery bulges seriously during storage. Contents of the invention [0003] The purpose of the present invention is to provide a nickel-zinc battery negative electrode substrate, which has the advantages of stable battery performance, long cycle life, low cost, simple substrate manufacturing process, good electrical conductivity and the like. [0004] In order to achieve the above object, the present invention is realized by the following technical solutions. [0005] A nickel-zinc battery negative electrode base ...
