Abstract
The utility model relates to a lithium ion battery is substrate for pole piece, including the even substrate body of thickness, still evenly be provided with a plurality of turn -ups opposite direction's last turn -ups hole, lower turn -ups hole on the body, last turn -ups hole, the internal diameter that descends the turn -ups hole, external diameter, hole flanging height, hole flanging fillet radius homogeneous phase are together. It is high that its aim at provides a pole piece packing density, and thick liquids attachment energy reinforce is difficult for coming off on the pole piece, and the volume energy who has just improved lithium ion battery greatly is than the lithium ion battery is substrate for pole piece with improving discharge rate.
Description
Technical field
The utility model relates to the manufacturing technology field of the electrode being made up of or comprising active material active material, particularly relates to a kind of base material manufacturing electrodes of lithium-ion batteries.
Background technology
Along with the progressively ripe of lithium ion battery manufacturing technology and the promotion of country to new forms of energy product, increasing auto vendor starts to develop electric automobile.But, because current electrodes of lithium-ion batteries base material is flake, the pole piece thickness made also only has 150 microns, volume energy is than limited, and very easily rupture when using, for preventing fracture, coating positive powder, negative electrode powder only can be thickeied on pole piece base material, but thicken coating after pole piece powder adhesive force weak, very easily come off, pole piece poor-performing, cause the course continuation mileage of existing pure electric automobile not reach the requirement of practical application far away, and easily cause the voltage consistency difference in Li-ion batteries piles when high-multiplying power discharge.Solve the problem the volume energy ratio and raising discharge-rate that must improve lithium ion battery constantly, to this, needs to improve electrodes of lithium-ion batteries base material, in order to the volume energy ratio and the discharge-rate that improve lithium ion battery to a certain extent.
Utility model content
It is high that the technical problems to be solved in the utility model is to provide a kind of pole piece packing density, and pole piece spreading mass adhesive ability is strong, difficult drop-off, and substantially increase the volume energy ratio of lithium ion battery and improve the electrodes of lithium-ion batteries base material of discharge-rate.
A kind of electrodes of lithium-ion batteries base material of the utility model, comprise the uniform material main body of thickness, described body is also evenly provided with contrary upper overturning hole, several flange directions, lower flanging bore, the internal diameter of described upper overturning hole, lower flanging bore, external diameter, hole flanging height, hole flanging radius of corner are all identical.
A kind of electrodes of lithium-ion batteries base material of the utility model, wherein said body is cuboid, and on the length direction, Width of described cuboid, described upper overturning hole, lower flanging bore are alternately to be arranged.
A kind of electrodes of lithium-ion batteries base material of the utility model, the thickness D1 of wherein said body is 9 ~ 15 microns, and the height D3 three sum of the height D2 in described thickness D1 and described upper overturning hole, lower flanging bore is 140 microns.
A kind of electrodes of lithium-ion batteries base material of the utility model, wherein said body is laminar Copper Foil or aluminium foil.
The utility model additionally provides a kind of pole piece adopting above-mentioned electrodes of lithium-ion batteries base material to make, and the thickness of described pole piece is 180 ~ 190 microns.
The difference of base material of the present utility model and existing base material is base material of the present utility model is provided with upper and lower flanging bore, and therefore, the pole piece packing density adopting base material of the present utility model to make is high, and pole piece spreading mass adhesive ability is strong, difficult drop-off.The lithium ion battery lithium ion in the process of discharge and recharge applying this kind of pole piece making moves by flanging bore, and this just substantially increases the volume energy ratio of lithium ion battery and improves discharge-rate.
Below in conjunction with accompanying drawing, a kind of electrodes of lithium-ion batteries base material of the present utility model is described further.

Embodiment
As shown in Figures 1 to 4, a kind of electrodes of lithium-ion batteries of the utility model base material comprises the uniform material main body 1 of the thickness be made up of laminar Copper Foil or aluminium foil, body 1 is cuboid, the thickness D1 of body 1 is 9 ~ 15 microns, the length direction of cuboid, Width is also evenly provided with on several flange directions, lower contrary upper overturning hole 2, lower flanging bore 3, upper overturning hole 2, the internal diameter of lower flanging bore 3, external diameter, hole flanging height, hole flanging radius of corner is all identical, and at above-mentioned length direction, on Width, upper overturning hole 2, lower flanging bore 3 is alternately to be arranged.Such structure adds the thickness of base material itself, and after upper overturning hole 2, lower flanging bore 3 are set, the height D3 three sum of the thickness D1 of the body 1 and height D2 in upper overturning hole 2, lower flanging bore 3 is 140 microns, the thickness of the battery pole piece that this base material is conveniently made after the technological means coating slurry such as positive powder, negative electrode powder can reach 180 ~ 190 microns, and this thickness is much larger than the thickness of existing pole piece 150 microns.
Base material of the present utility model arranges multiple upper overturning hole 2 respectively on body 1, lower flanging bore 3, define the base material of the three-dimensional structure of two-sided flange, the thickness of filling space and base material is added compared with normal thin chip base material, the break resistance of base material is also increased greatly, therefore, base material of the present utility model does not need to thicken coating powders slurry when making pole piece also can ensure pole piece breaking resistance, thus ensure that the adhesive force of powder slurries, efficiently avoid slurry to come off the adverse effect caused pole piece performance, and do not apply blocked up slurry, also enterprise's production cost is greatly reduced.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that the utility model claims determine.
