Abstract
The utility model relates to an insulating tape, in particular to the insulating tape for a lithium ion battery. A plurality of through holes for the passing of electrolyte are arranged on the surface of a tape substrate onto which an adhesive layer is attached. Compared with the prior art, the insulating tape has the beneficial effects that since the through holes are arranged on the tape substrate to facilitate the passing of the electrolyte, the electrolyte can be effectively compensated when the lithium ion battery is used and the service life of the battery can be greatly improved.
Description
Technical field
The utility model relates to a kind of insulating tape, relates in particular to a kind of insulating tape that is used for lithium ion battery.
Background technology
At present; lithium ion battery need paste one deck protective tapes in the lithium ion battery bottom in the shell of packing into the time; the wound of consulting when preventing that the utmost point group from going into shell; be called " insulating tape that has air discharge duct " publication number CN201520736 U as Chinese utility model patent name and disclose a kind of insulating tape; comprise glue-line and foundation base; foundation base is provided with the network of convex; glue-line is attached to the front of basic unit's face; the glue-line front presents the corresponding concavity network that gets with protruding network; so this adhesive tape contacts with battery surface tightly owing to having the concavity network on basic unit's face; can not produce drum; but the base material of its foundation base all is very fine and close material has hindered passing through of electrolyte; make electrolyte local overstocked, thereby influenced the life-span of battery.
The utility model content
In view of this, the utility model purpose is for a kind of ageing-resistant, long service life is provided, a kind of insulating tape that is used for lithium ion battery that can penetrating electrolyte.
For this reason, the utility model provides a kind of insulating tape that is used for lithium ion battery, and the adhesive band base surface that is attached with glue-line is provided with a plurality of through holes by electrolyte.
Preferably, described through hole uniformity on adhesive band base is arranged, and through-hole diameter is the 20-50 micron.
Preferably, described glue-line attached to the outward flange of adhesive band base or segmentation attached on the adhesive band base surface.
Preferably, described glue-line is acrylic glue or silica gel.
Preferably, the material of described adhesive band base is polypropylene or PETG or polyimides.
Compared with prior art, thereby the utility model is owing to be provided with a plurality of through holes and help passing through of electrolyte on adhesive band base, make lithium ion battery in use electrolyte obtain effectively replenishing the useful life of greatly having improved battery.
Description of drawings
Fig. 1 is the utility model contour structures schematic diagram.
Fig. 2 is the utility model cross-sectional view.
Fig. 3 is the utility model section enlarged diagram.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of insulating tape that is used for lithium ion battery, comprise adhesive band base 1 and glue-line 2, on the surface of described glue-line 2 attached to adhesive band base 1, for make battery in use electrolyte can obtain effectively replenishing, be provided with a plurality of through holes 3 that can pass through electrolyte on described adhesive band base 1 surface, in use electrolyte can carry out the additional exchange of electrolyte by through hole 3, through hole 3 diameters are the 20-50 micron, through hole 3 can be that uniformity is arranged on the adhesive band base 1, also can be irregular arrangement, on adhesive band base, be regular shape arrangement for the through hole 3 that makes easy to process usually.For the better effect of performance through hole 3, described glue-line 2 attached on adhesive band base 1 surface, has so just reduced the quantity of glue-line 2 obstruction through holes 3 attached to the outward flange of adhesive band base 1 or segmentation.Described glue-line 2 is acrylic glue or a silica gel commonly used on the market.The material of described adhesive band base 1 is elected polypropylene (PP) or PETG (PET) or polyimides (PI) as.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
