fig. 3 is a diagram illustrating the effect of the present invention.
Detailed Description
As shown in fig. 1 to 3, a lithium ion battery gum isolation pad comprises a substrate layer 1 and a glue layer 2 laid on the substrate layer 1, and positioning grooves 3 convenient for the end portions of battery tabs to penetrate are arranged on the substrate layer 1 and the glue layer 2. This gum isolation pad is installed at the 4 tip of electric core of battery, and utmost point ear 5 on the electric core 4 runs through constant head tank 3.
Wherein, the material of substrate layer 1 is electrolyte-resistant PET PP material, and the material of glue film 2 is acrylic glue material. The thickness of the substrate layer 1 is 0.1-1.0mm, and the thickness of the adhesive layer 2 is 0.03-0.15 mm.
The quantity of constant head tank 3 is unanimous with the quantity of utmost point ear 5 on the electric core, and the width of constant head tank 3 is greater than the width of utmost point ear 5.
The shape of the gum isolation pad comprises structures which are not limited to circular, annular, square, concave-convex, 8-shaped and the like, and is determined by the adaptation requirement of the actual lithium ion battery tab structure.
When the back-adhesive isolation pad is used, the back-adhesive isolation pad is arranged on the lug 5 of the battery cell 4, the back-adhesive layer 2 of the back-adhesive isolation pad is adhered to the battery cell main body, the lug 5 penetrates through the positioning groove 3 of the isolation pad, the isolation pad is directly fixed, adhesive paper is not needed for additional fixing operation, adhesive paper fixing operation procedures are saved, and the problems of looseness, instability and the like in adhesive paper fixing are avoided; meanwhile, in the soft package battery with the aluminum plastic film shell, the gum isolation pad also solves the problem of the shape and appearance of the gummed paper for fixing the isolation pad.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
