Description
Technical field
This utility model relates to the cell stack structure in a kind of battery manufacture.
Background technology
Along with the continuous consumption of the energy, people are increasing to the demand of the energy, and the requirement to the energy is harsher simultaneously, and the demand as the secondary cell of one of new forms of energy is also increasing, and therefore, have been carried out the much research about secondary cell.
Rectangular cell is the most common production cell shapes, and rectangular cell can be good at applying in some mobile devices.No matter it is from the standpoint of battery material, or still other aspects from the standpoint of the processing technology of battery core, the research direction of secondary cell is high-energy-density, high discharge voltage and high power stability and good security performance.
The manufacture method of current battery battery core mainly has two kinds: one is takeup type battery core, and one is lamination type electric core.The former is mainly sequentially overlapped winding, this battery formation efficiency height, but the easy crumple of battery core, and the size of the number of plies of winding and pole piece is subject to certain restrictions by the positive plate not cut off continuously, barrier film, negative plate, barrier film.The latter is mainly sequentially overlapped by the positive/negative plate cut off and has barrier film to separate.Laminated batteries has more preferable battery performance, all concentrates on this direction of laminated batteries, the mainly processing technology of laminated batteries now with a lot of probing into.At present, the making thinking of laminated batteries is Z-type lamination and takeup type lamination.Z-type lamination production efficiency is the highest comparatively speaking.The most common takeup type laminated batteries is to be combined with each other by the barrier film of positive/negative plate and cut-out, and the security performance of this laminated batteries is relatively poor.
Utility model content
This utility model is the highest for the middle production efficiency of prior art, the most high technical problem of laminated batteries safety, it is provided that a kind of production efficiency is high, the laminated batteries that security performance is high.
This utility model is achieved through the following technical solutions:
A kind of takeup type laminated batteries, including relative adhesion positive plate on two faces of barrier film and negative plate, described positive plate and negative plate are turned off discontinuous monolithic, and described barrier film is the barrier film not cut off continuously.
A kind of takeup type laminated batteries, what described barrier film was divided into being adhered fixed positive/negative plate adheres to barrier film and in order to the protection barrier film being placed on viscosity barrier film.
Takeup type laminated batteries, along the direction of winding, the distance between adjacent pole piece becomes larger.
Takeup type laminated batteries, described positive plate and the lug being provided with extension on negative plate on identical bearing of trend.After positive plate and negative plate are superimposed, the described lug on positive plate and the lug on negative plate are crisscross arranged, not in a fore-and-aft plane.
Takeup type laminated batteries, described positive plate and the quantity of negative plate are set to more than the quantity of positive plate one of the quantity of negative plate.The length and width of positive plate is respectively less than the length and width of negative plate.
This utility model uses the barrier film not cut off continuously being, and the viscosity barrier film that is divided into being adhered fixed positive/negative plate and in order to the protection barrier film being placed on viscosity barrier film.So can be sufficiently spaced from electrode plates, sufficiently improve the safety of battery.Utilizing technical solutions of the utility model can design the capacity of battery according to the quantity of pole piece, the processing technology of this laminated batteries Z-type laminated batteries that compares has higher production efficiency, is suitable for large-scale production.Positive plate and the negative plate position on barrier film, is not continuous wide placement, along the direction of winding, distance between pole piece is increasing, because the increase of rolling thickness, the gap of adjacent pole piece is accomplished by increasing corresponding distance, is alignment with the battery core pole piece after ensureing winding.The lug being crisscross arranged, it is simple to the connection of components and parts during use.
Accompanying drawing explanation
Fig. 1 is the core strueture profile of this utility model takeup type laminated batteries.
Fig. 2 is that before this utility model takeup type laminated batteries winds in place, positive/negative plate is placed on the top view on barrier film.
Detailed description of the invention
See shown in accompanying drawing 1,2.Takeup type laminated batteries, is turned off discontinuous monolithic including relative adhesion positive plate 4 on two faces of barrier film and negative plate 3, positive plate 4 and negative plate 3, and barrier film is the barrier film not cut off continuously.Viscosity barrier film 1 that barrier film is divided into being adhered fixed positive/negative plate and in order to the protection barrier film 2 being placed on viscosity barrier film 1.Along the direction of winding, the distance between adjacent pole piece becomes larger.Positive plate 4 and the lug 5 being provided with extension on negative plate 3 on identical bearing of trend.After positive plate 4 and negative plate 3 are superimposed, the lug 5 on positive plate 4 and the lug 5 on negative plate 3 are crisscross arranged, not in a fore-and-aft plane.The quantity of positive plate 4 and negative plate 3 is set to more than the quantity of positive plate 4 one of the quantity of negative plate 3.The width of positive plate 4 is less than the width of negative plate 3.
The core strueture of this takeup type laminated batteries, first positive plate 4 cuts into slices, it is cut into according to technological requirement and produces the specification needed, negative plate 3 is also required to cut into slices equally, complete the section work of positive/negative plate, positive/negative plate is captured followed by certain grabbing device, the positive/negative plate captured is placed and the upper and lower surface of viscosity barrier film 1 respectively, by transporter by positive plate 4, viscosity barrier film 1, negative plate 3 is sent to heat composite apparatus together, heat composite apparatus completes positive plate 4 exactly, viscosity barrier film 1, the composite task of negative plate 3, positive plate 4 and negative plate 3 is made to be fixed on viscosity barrier film 1；Winding followed by laminated batteries; the distance between adjacent pole piece is determined before winding; along coiling direction, spacing increases, then passes through spooler installation; place one layer of viscosity barrier film 1 having positive/negative plate and one layer of protection barrier film 2; setting winding process, two-layer barrier film starts winding to coiling direction simultaneously, completes winding according to process requirements; winding terminate in barrier film edge, carry out rubberizing process.
Utilize this utility model can design the capacity of battery according to the quantity of pole piece; the processing technology of this laminated batteries Z-type laminated batteries that compares has higher production efficiency, is suitable for large-scale production, simultaneously; the positive/negative plate of this laminated batteries is isolated more comprehensively, has higher safety.
