Abstract
The utility model belongs to the field of the industrial production and particularly relates to a current collector using a stainless steel woven mesh as a battery pole piece. The novel current collector adopts the stainless steel woven mesh as the battery pole piece. As the woven mesh current collector used in the battery pole piece is softer than a stretching mesh, the randomness is good, and the probability of a hidden danger of a short circuit is low. When the novel current collector is in practical use, a cutting edge of the stainless steel woven mesh forms angles of 45 degrees with warps and wefts instead of being parallel to some edge, the malleability of the current collector is improved, the probability of the falling-off of a metal wire is reduced, and the hidden danger of the battery short circuit caused by the falling-off of the metal wire is avoided.
Description
Technical field
The utility model belongs to field of industrial production, relates to specifically a kind of collector that uses the stainless steel mesh grid to do battery pole piece.
Background technology
In the pole piece of some battery, need to do collector with wire netting, adopt at present nickel or stainless stretching nets more, but because the corner of stretching nets is harder, may form and puncture the hidden danger that battery diaphragm causes short circuit, the battery that especially need to use in than the strong vibration environment is more dangerous.Need a kind of new material of this hidden danger of can avoiding to do collector.If stretching nets is cut into the rectangular set fluid by the vertical direction of graticule, the edge stainless steel wire easily comes off, and affects product quality.
The utility model content
The utility model is intended to overcome the deficiency of prior art and battery pole piece current collector structure, and a kind of new current collector structure is provided.
A kind of new current collector is characterized in that, adopts the stainless steel mesh grid to do the battery pole piece collector.
Because it is more soft than stretching nets that the mesh grid collector is used in the battery pole piece, good with type, the probability that forms short circuit hidden danger is low.
In actual use, the utility model is by the cutting edge of stainless steel mesh grid and warp and parallel are formed miter angle but not be parallel to a certain limit, strengthened the ductility of collector, reduced simultaneously the probability that wire comes off, avoided causing the hidden danger of battery short circuit because wire comes off.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 warp, 2 parallels.
Embodiment
With reference to the accompanying drawings 2, the utility model is further described:
A kind of new current collector is characterized in that, adopts the stainless steel mesh grid to do the battery pole piece collector.
Described stainless steel mesh grid is 100 orders.
The string diameter of described stainless steel mesh grid is 0.05mm.
The warp 1 of described stainless steel mesh grid and parallel 2 are miter angle with cutting edge.
The utility model is by the cutting edge of stainless steel mesh grid and warp and parallel are formed miter angle but not be parallel to a certain limit, strengthened the ductility of collector, reduced simultaneously the probability that wire comes off, avoided causing the hidden danger of battery short circuit because wire comes off.
