Abstract
The invention relates to the field of battery pole piece processing, in particular to a battery pole piece coating method. The method includes the following steps of S1, arranging coating areas on the two sides of a coating machine according to the width of a battery pole piece respectively, wherein the gap between the two coating areas is a blank area; S2, starting the coating machine so that the two coating areas can conduct continuous coating on the two sides of a base material in the movement direction of the base material. The coating method is little in material waste after die cutting and high in resource utilization rate.
Description
Technical field
The present invention relates to battery pole piece manufacture field, particularly relate to a kind of battery pole piece coating method.
Background technology
Lithium ion battery is the new generation of green high-energy battery that performance is remarkable, it has also become the weight of hi-tech development
One of point.Lithium ion battery have the following characteristics that high voltage, high power capacity, low consumption, memory-less effect,
Nuisanceless, volume is little, internal resistance is little, self discharge is few, cycle-index is many.Because of its These characteristics, lithium-ion electric
Pond has application to the numerous civilian and military fields such as mobile phone, notebook computer, video camera, digital camera.
Pole piece, as the important component part of lithium battery, serves vital in the performance of battery
Effect.Pole piece be made by base material both side surface be coated with pole powder material and make, be therefore coated with work
Skill is the important step that pole piece makes.
As it is shown in figure 1, the base material schematic diagram after being coated with for prior art.The coating process of prior art pole piece,
It is to entreat coating in the substrate, after being coated with, is cut the waste material on both sides, applying area by cutting die, this
Mode, the waste material of generation is more, and raw material availability is low, causes the wasting of resources.
Summary of the invention
For solving the problems referred to above, the present invention provides the battery pole that after a kind of cross cutting, waste material is few, resource utilization is high
Sheet coating process.
The technical solution adopted in the present invention is: a kind of battery pole piece coating method, comprises the following steps, one
Kind of battery pole piece coating method, it is characterised in that: comprise the following steps, S1, width according to battery pole piece
Be respectively provided with applying area in the both sides of coating machine, the gap between two applying area for being left white district, S2, unlatching
Coating machine, base material both sides are coated with continuously by two applying area along substrate transport direction.
Being improved to further technique scheme, in S1, the width of described applying area and battery pole piece
Width matches；The width of described battery pole ear is 0.85:1～0.95:1 with the width ratio being left white district.
The invention have the benefit that
1, in the present invention, by being coated with in the both sides of base material, during cross cutting, lug can be cut out by being left white district, one
The secondary two pieces of pole pieces cutting out mirror image dislocation symmetry, applying area, both sides can make full use of, and central authorities are left white district also
Can make full use of, after cross cutting, waste material is few, and resource utilization is high, and owing to using this kind of coating process to coordinate after
Continuous cutting die, once can prepare two pieces of pole pieces, is conducive to improving pole piece production efficiency.
2, in S1, the width of described applying area matches with the width of battery pole piece, and applying area can be by fully profit
With, during cross cutting, base material edge is completely used as pole piece main body, basic edge no waste mine, is not required to carry out edge and cuts
Useless, simplify pole piece production technology, improve pole piece production efficiency, and resource utilization is high；Battery pole ear
Width, with to be left white the width ratio in district be 0.85:1～0.95:1, is left white the width width slightly larger than battery pole ear in district,
It is left white waste material after district cuts out lug few, and the edge of the edge Yu lug owing to being left white district exists gap,
It is easy to being smoothed out of cross cutting, is conducive to improving pole piece production efficiency.
Accompanying drawing explanation
Fig. 1 is the base material schematic diagram after prior art coating；
Fig. 2 is the base material schematic diagram after the present invention is coated with；
Fig. 3 is the base material cross cutting schematic diagram after the present invention is coated with.

Cut schematic diagram.
In the present invention, a kind of battery pole piece coating method, comprise the following steps, S1, according to battery pole piece
Width is respectively provided with applying area in the both sides of coating machine, the gap between two applying area for being left white district, S2,
Opening coating machine, base material both sides are coated with continuously by two applying area along substrate transport direction.
In the present invention, by being coated with in the both sides of base material, during cross cutting, lug can be cut out by being left white district, once
Can cut out two pieces of pole pieces that mirror image dislocation is symmetrical, applying area, both sides can make full use of, and central authorities are left white Qu Yeneng
Making full use of, after cross cutting, waste material is few, and resource utilization is high, and follow-up owing to using this kind of coating process to coordinate
Cutting die, once can prepare two pieces of pole pieces, is conducive to improving pole piece production efficiency.
In S1, the width of described applying area matches with the width of battery pole piece, and applying area can be fully utilized,
During cross cutting, base material edge is completely used as pole piece main body, basic edge no waste mine, is not required to carry out edge and cuts useless,
Simplify pole piece production technology, improve pole piece production efficiency, and resource utilization is high.
The width of battery pole ear is 0.85:1～0.95:1, in the present embodiment, battery pole ear with the width ratio being left white district
Width be 0.9:1 with the width ratio being left white district.It is left white the width width slightly larger than battery pole ear in district, is left white
After district cuts out lug, waste material is few, and the edge of the edge Yu lug owing to being left white district exists gap, it is simple to
Being smoothed out of cross cutting, is conducive to improving pole piece production efficiency.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
