Embodiment Construction

[0016] In order to further understand the invention content, characteristics and effects of the present invention, the following embodiments are enumerated hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0017] Refer to attached figure 1 , taking the F-type 10Ah zinc-nickel battery as an example:

[0018] A copper alloy material is selected to be processed into a battery shell 3 and a battery cover 1, and the battery cover 1 is welded by a cover bottom and a cap.

[0019] Making the positive plate: choose foamed nickel as the positive base, and will contain additives, binder Ni(OH) 2 The positive electrode material after mixing is filled into nickel foam, and the positive electrode 4 is made by drawing or sintering, and then dried, rolled, cut, cleaned, and then welded on the positive electrode tab 8 .

[0020] Making the negative plate: the negative base is made of copper alloy mesh, and the negative active material is mixed...

Abstract

The invention belongs to cylindrical zinc-nickel accumulators, comprising an anode in a battery shell, a polar plate group which is winded by a septum and a cathode, and a battery cover. The invention is characterized in that the cathode is a flexible zinc electrode and the anode is a nickel electrode; the battery shell and the battery cover are both made of copper or copper alloy material; the flexible zinc electrode consists of a cathode framework and cathode active matter on the cathode framework; the cathode framework is a netting or perforation belt or mesh grid, which is made of copper or copper alloy; the cathode active matter is the admixture of zinc or zinc oxide powder which takes one or more compounds out of calcium, lead, indium and tantalum as additive. As the flexible zinc electrode is taken as the cathode, the nickel electrode is taken as the anode and the copper or copper alloy material is taken as the battery shell and the shell cover, the specific energy of the battery is improved, the cost is reduced, and the invention can be taken as all power supplies.

Description

technical field [0001] The invention belongs to the technical field of chemical power sources, in particular to a cylindrical zinc-nickel storage battery. Background technique [0002] As the oil energy crisis becomes more and more serious and the voice of urban pollution control becomes stronger and stronger, electric vehicles and hybrid vehicles emerge as the times require. Therefore, people's demand for energy with high specific energy, low price, and no pollution is imminent. Because zinc-nickel batteries theoretically meet the above characteristics, they have become the focus of attention for electric vehicle power supplies. [0003] Currently known zinc-nickel accumulators have not yet reached the ideal state of high specific energy, low price, and no pollution due to battery shell materials, electrode skeletons, active materials, and battery structure problems. Contents of the invention [0004] In order to solve the problems in the prior art, the invention provide...
