Background

With the increasing exhaustion of petroleum, coal and other fossil resources around the world, a series of high-performance and pollution-free green new energy technologies are developed at home and abroad, which has positive significance for relieving the current energy crisis. The aluminum air battery is a special fuel battery, and becomes one of clean energy sources with the greatest development prospect, and the prior art generally uses a nickel screen as a positive plate of the aluminum battery.

Chinese patent application No. CN201921786442.8 discloses a metal mesh for a cathode of a nickel-metal hydride battery, which comprises a body and a plurality of polygonal meshes distributed on the body, wherein the polygonal meshes are not less than six sides. The utility model provides a metal mesh for nickel-hydrogen battery negative pole is difficult to warp, guarantees the performance of battery, though this patent compares the rhombus mesh through setting up polygon mesh to be no less than six limits, can increase the area of mesh on the one hand, on the other hand because the mesh has many limits to support, can make the mesh have better bearing capacity, after the mesh fills active material, the mesh structure is difficult to warp tensile; however, the positive electrode nickel net of the patent has smooth surface and small specific surface area, and cannot support more catalytic materials.

Chinese patent application No. CN202021131322.7 discloses an anti-slip type burning nickel net, which comprises a nickel net body with a square structure, a first transverse nickel wire, a second transverse nickel wire and a longitudinal nickel wire; although this patent is through setting up the line footpath of first horizontal nickel wire, the horizontal nickel wire of second and vertical nickel wire is all inequality for nickel net body surface constitutes unsmooth structure, has increased the specific surface area of nickel net, this patent does not belong to battery technical field, and does not disclose its unsmooth structure yet and have the effect of bearing more catalytic material, and this patent is through setting up horizontal nickel wire and vertical nickel wire to the line footpath inequality, weave the mode that forms the nickel net body through horizontal nickel wire and warp nickel wire again, have the technology complicacy, make the defect of difficulty.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims to provide a simple process, can increase the specific surface area of nickel net body, make the nickel net can bear more catalytic material's sandblast nickel net for the aluminium-air battery.

In order to solve the technical problem, the technical scheme of the utility model is that: a sand blasting nickel screen for an aluminum-air battery comprises a nickel screen body, wherein the nickel screen body comprises a nickel screen body base material and nickel screen ribs, and the nickel screen body base material and the nickel screen ribs are crossed to form nickel screen meshes; the surfaces of the nickel mesh body base material and the nickel mesh ribs are provided with a plurality of micro-pits.

Preferably, the nickel screen meshes are diamond-shaped nickel screen meshes.

Preferably, the surface of the nickel mesh body is formed with micro-pits by a sand blasting process.

Preferably, the nickel screen body is of a square structure.

Preferably, the nickel screen mesh body base material is of a nickel alloy material structure, and the material of the nickel screen ribs is the same as that of the nickel screen mesh body base material.

The utility model discloses technical effect mainly embodies: through the micro-pits on the nickel screen body base material and the nickel screen ribs, the surface roughness of the nickel screen body can be improved, the specific surface area of the nickel screen body is increased, the content of a catalyst which can be borne by the nickel screen body is improved, and the catalytic activity point positions are increased, so that the overall performance of the battery is improved, the micro-pits can be formed on the surfaces of the nickel screen body base material and the nickel screen ribs through a sand blasting process, the process is simple, and the manufacturing is convenient.
