Abstract
The utility model discloses a pinhole-shaped battery pole piece. The pinhole-shaped battery pole piece comprises a pole piece (1), wherein a plurality of groups of pinholes (2) which are arranged transversely are arranged on the pole piece (1); each group of the pinholes (2) are distributed on the pole piece (1) longitudinally; and a strip-shaped transition area (3) is formed between two adjacent pinholes (2). In the pinhole-shaped battery pole piece, pinholes are reserved on the pole piece, so that the battery reaction area of a square battery is increased greatly, a heat conduction route is changed, ventilation and radiation channels of the battery are increased, and effective radiation of the battery is realized.
Description
Technical field
The utility model relates to a kind of pin hole shape battery pole piece, is specially adapted to the battery pole piece of rectangular cell.
Background technology
The structure of square battery and structural member moulding thereof are simple, and battery production technology is simple, and equipment is ripe, and automaticity is high, is widely used in quadratic form ickel-cadmium cell, lithium ion battery, Ni-MH battery etc.But present rectangular cell exists following shortcoming: the pole piece structure of square battery has caused the area of dissipation of battery, pole plate flow conductivity limited; Sheet number increase along with battery pole piece; The heat that inside battery produces is difficult to effectively be dispersed into outside batteries, causes the battery heat accumulation serious.In addition battery when charging the ion guide general character poor with gas permeability, hydrogen-oxygen or ion are compound untimely, the reaction rate of increase side reaction; Caused inner pressure of battery very high; Therefore present rectangular cell generally limits the pole piece sheet number of square battery, and pole piece can not be done too much, and this has just limited the specific area of inside battery chemical reaction; Cause battery hydrogen-oxygen or the ion composite performance is relatively poor and heat production is too many when large current charge, limited the lifting of battery high-rate performance.
Summary of the invention
The utility model provides a kind of pin hole shape battery pole piece, and it leaves pin hole on pole piece, has increased the cell reaction area of square battery so greatly, changes the heat conduction stroke, has increased the ventilation and heat passage of battery again, has realized the battery efficiently radiates heat.
The present invention has adopted following technical scheme: a kind of pin hole shape battery pole piece, and it comprises pole piece, is distributed with some groups of transversely arranged pin holes on the described pole piece, each is organized pin hole and vertically is distributed on the pole piece, between two groups of adjacent pin holes, is provided with banded transition region.
The horizontal spacing of described each pin hole is 0.1-5mm, and longitudinal pitch is 0.1-5mm.Described pin hole is a circular port.Described pin hole is an irregularly-shaped hole.
The present invention has following beneficial effect: be distributed with the horizontal and vertical pin hole that is interspersed on the pole piece of the present invention, can increase the area of rectangular cell reaction so greatly, change the heat conduction stroke; And increased the ventilation and heat passage of battery, and realize heat radiation effectively, increased the specific area of electrode reaction simultaneously; Strengthened the ion negotiability; Production technology and process units are changed very little, are prone to realize, practice thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
In Fig. 1, the utility model is a kind of pin hole shape battery pole piece, and it comprises pole piece 1; Be distributed with some groups of transversely arranged pin holes 2 on the pole piece 1, pin hole 2 is circular port or irregularly-shaped hole, and each is organized pin hole 2 and vertically is distributed on the pole piece 1; The horizontal spacing of each pin hole 2 is 0.1-5mm, and longitudinal pitch is 0.1-5mm, between two groups of adjacent pin holes 2, is provided with banded transition region 3; Pin hole on the utility model pole piece adopts special mould for punching to bore a hole; Be provided with the resilience device between the cope match-plate pattern of special mould for punching and the backboard, the punching of cope match-plate pattern and special mould for punching to dash pin corresponding, the big 0.05-1 mm of diameter of the aperture specific impulse pin of punching.Still adopt the mode of production of lamination when adopting this electrode plates to produce battery, the fusion weld modes such as using Laser Welding, argon arc welding of sealing of battery realizes the battery case sealing.
