Abstract
The utility model relates to a flow concentration pull net foam nickel (copper) which belongs to the technical field of the battery electrode. One surface or two surfaces of a three-dimensional stereo foam nickel (copper) are provided with a sheet nickel (copper) net layer, the net hole of the nickel (copper) net is hexagonal, or square, or circular, the thickness of the nickel (copper) net is from 0.1 mm to 0.2 mm, and the thickness of foam nickel (copper) is from 1.5 mm to 3.0 mm. The utility model has the advantages of high strength, the capability of continuous production, good afflux performance, good contact of the poles with the substrate under the 25 A high current and the good active material filling of the batteries.
Description
The utility model relates to collecting type and draws in the net nickel foam (copper), belongs to the battery electrode technical field.
The high energy secondary cell as nickel-cadmium cell and nickel-hydrogen cell, wherein all has the afflux skeleton, and the afflux skeleton of prior art has two classes, and the one, nickel plating Punching steel strip, the 2nd, nickel foam.The former intensity height can be produced continuously, but steel band is wanted first punching nickel plating again, complex manufacturing, and in addition, Punching steel strip belongs to planar structure, and with regard to the characteristic of semiconductor active material, its catchment effect is bad, is unsuitable for high performance secondary cell.Nickel foam is a space network, cell active materials is filled simple, and conductivity collection good fluidity can be used for producing the battery of high power capacity, but because of its intensity low, and can't produce continuously, monolithic production cost high-quality instability is being used for the production easy fracture of battery pole plates, in addition, though this nickel foam afflux is good, the confluxing property of big electric current is poor, is unsuitable for heavy-current discharge.
The purpose of this utility model is, remedies the deficiency of prior art, provides the good collecting type of the big performance of a kind of intensity to draw in the net nickel foam (copper).
The purpose of this utility model realizes by following technical measures.
Nickel (copper) stratum reticulare is arranged on 3 D stereo nickel foam (copper) sheet.
Nickel (copper) net is positioned at the one or both sides of nickel foam (copper) sheet.The former claims single face to draw in the net nickel foam (copper), and the latter claims the two-sided nickel foam (copper) of drawing in the net.
The mesh of above-mentioned nickel (copper) net can be a hexagon, also can be square or circular, aperture 0.5-2.0mm.The thick 0.1-0.2mm of nickel (copper) net, the thick 1.5-3.0mm of nickel foam (copper).
Compared with the prior art the utility model has the following advantages:
1. the intensity height can produce lengthy motion picture continuously, during use as required the size cutting get final product, be convenient to the storage, the transportation.
2. the afflux performance is good, contacts with matrix at the big electric current lug of 25A.
3. cell active materials is populated, and the loading average deviation is lower than 1.5%.
Be described further below in conjunction with double utility model of drawings and Examples.
Fig. 1 is that the utility model single face draws in the net nickel foam (copper) schematic cross-section.
Fig. 2 is two-sided nickel foam (copper) schematic cross-section that draws in the net of the utility model.
Fig. 3 is the utility model hexagonal mesh nickel (copper) wire side schematic diagram.
Wherein, 1. nickel foam (copper), 2. nickel (copper) net, 3. hexagon mesh.
Embodiment 1. structures as shown in figures 1 and 3.
On the 3 D stereo nickel foam sheet one side nickel screen layer is arranged; The mesh hexagon of nickel screen, aperture 1.5mm, the thick 0.2mm of nickel screen, the thick 3.0mm of nickel foam.
All there is copper mesh layers on 3 D stereo foam copper sheet two sides; The mesh of copper mesh is circular, aperture 2mm, the thick 0.1mm of copper mesh, the thick 2.0mm of foam copper.
Claims (4)
1. collecting type draws in the net nickel foam (copper), it is characterized in that nickel (copper) stratum reticulare is arranged on 3 D stereo nickel foam (copper) sheet.
2. collecting type as claimed in claim 1 draws in the net nickel foam (copper), it is characterized in that nickel (copper) net is positioned at the one or both sides of nickel foam (copper) sheet.
3. collecting type as claimed in claim 1 draws in the net nickel foam (copper), it is characterized in that the mesh of described nickel (copper) net is a hexagon, square or circular.
4. collecting type as claimed in claim 1 draws in the net nickel foam (copper), it is characterized in that the thick 0.1-0.2mm of described nickel (copper) net, the thick 1.5-3.0mm of nickel foam (copper).
