Embodiment
To be described in further detail the utility model embodiment below.
Polymer Li-ion battery encapsulating structure of the present utility model, its preferably embodiment be:
By the minor face of the side of aluminum plastic film to a direction folding 90 degree, opposite side is to the long limit of another direction folding 90 degree, core is put into the aluminum plastic film after flanging, wherein, the position of not rolling in the middle part of aluminum plastic film is attached to the end face of described core, minor face after folding is attached on the tab inside lug, and described in the long edge after folding, the bottom reversed 180 degree of core is attached on the tab outside described lug, then carries out closedtop and side seal to the aluminum plastic film of parcel core.
The edge on described minor face and long limit all only reaches the position of described tab half.
Described lug comprises the aluminium pole ears as positive pole and the nickel lug as negative pole.
The utility model solves conventional aluminum plastic film and rushes the problem that nest packaged battery thickness can not be excessive, improves production efficiency, reduces production cost.
Specific embodiment:
As shown in Figures 1 to 4, the aluminum plastic film 1 cut out is carried out fold shaping by trimmer, the minor face 1-1 of 90 degree is rolled in the side of aluminum plastic film 1 to a direction, opposite side is to the long limit 1-2 of another direction folding 90 degree, battery core (core 4) after winding is put into the aluminum plastic film after fold shaping 1, wherein, the position of not rolling in the middle part of aluminum plastic film 1 is attached to the end face of core 4, minor face 1-1 after folding is attached on the tab 2 inside lug 3, long limit 1-2 after folding is attached on the tab 2 outside lug 3 along the bottom reversed 180 degree of core 4, the edge of minor face 1-1 and long limit 1-2 all only reaches the position of tab 2 half, pass through closedtop again, side seal completes cell package.
Application utility model, the production not being only enterprise is raised the efficiency, and raw material decrease waste, and production process is easy to control, production raw material are substantially lossless, and production efficiency is high, is mature and reliable technically.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
