Description
Technical Field
The utility model belongs to the technical field of the PC membrane is relevant, concretely relates to fire-retardant PC membrane of lithium cell insulation.
Background
Lithium batteries are batteries using lithium metal or lithium alloy as positive and negative electrode materials and using nonaqueous electrolyte solutions. In order to prevent short circuit caused by external metal contacting the outer wall of the battery during charging, the periphery of the lithium battery needs to be wrapped with an insulating flame-retardant PC film.
The existing insulation flame-retardant PC film of the lithium battery is only wrapped by a single layer, the corners of the lithium battery are quite sharp, and the PC film is covered on the surface of the lithium battery and is very easy to abrade and cut to cause damage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fire-retardant PC membrane of lithium cell insulation to the fire-retardant PC membrane of current lithium cell insulation who proposes in solving above-mentioned background art only adopts the individual layer parcel, and the edge of lithium cell often very sharp, and PC membrane covers and very easily causes the cutting of wearing and tearing to cause damaged problem on it.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an insulating fire-retardant PC membrane of lithium cell, is including covering rete and wear-resisting strip, wear-resisting strip body coupling is installed on the surface of covering the rete, still there is the right angle empty storehouse between covering rete and the wear-resisting strip.
Preferably, the wear-resistant strips are arranged on the surface of the covering film layer in parallel in multiple rows at equal intervals, and the width of each wear-resistant strip is five millimeters.
Compared with the prior art, the utility model provides an insulating fire-retardant PC membrane of lithium cell possesses following beneficial effect:
the utility model discloses a wear-resisting strip and right angle vacant lot, the PC membrane is adjusted the parcel in the battery outer layer according to the big or small shape of battery when the laminating, correspond the laminating with wear-resisting strip and battery edge during the parcel, the right angle vacant lot can be perfect when the laminating covers at the battery edge and the right angle edge joint of battery is fixed, wear-resisting strip has then thickened the thickness of battery edge rete, thicken the protection between the battery edge to PC membrane and sharpness, prevent that the PC membrane from suffering the cutting and breaking, and the cover is then formed the air chamber at the inside right angle vacant lot of wear-resisting strip on battery surface, can play fine cushioning effect when the battery receives the striking.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description, do not constitute a limitation of the invention, in which:
fig. 1 is a side sectional view of an insulating flame-retardant PC film for a lithium battery provided by the present invention;
in the figure: 1. covering the film layer; 2. wear resistant strips; 3. and (5) emptying the bin at a right angle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution:
the utility model provides an insulating fire-retardant PC membrane of lithium cell, is including covering rete 1 and wear-resisting strip 2, and wear-resisting strip 2 body coupling is installed on the surface of covering rete 1, and wear-resisting strip 2 equidistance multirow parallel mount is on the surface of covering rete 1, and wear-resisting strip 2's width is five millimeters. Cover rete 1 for insulating fire-retardant PC membrane, the length and width that covers rete 1 can be adjusted according to battery parcel needs, and wear-resisting strip 2's width is five millimeters apart from multirow parallel mount on the surface that covers rete 1, and personnel can wrap up according to the condition at battery edge and make wear-resisting strip 2 correspond the laminating with the battery edge.
A lithium battery insulation flame-retardant PC film comprises a covering film layer 1 and a wear-resistant strip 2, wherein a right-angle empty bin 3 is arranged between the covering film layer and the wear-resistant strip. Wear-resisting strip 2 when the laminating covers at the battery edge right angle empty storehouse 3 can be perfect fixed with the right angle edge joint of battery, wear-resisting strip 2 has then thickened the thickness of battery edge rete, thicken the protection between PC membrane and sharp battery edge, prevent that the PC membrane from suffering the cutting and breaking, and cover right angle empty storehouse 3 inside wear-resisting strip 2 on battery surface then forms the air chamber, can play fine cushioning effect when the battery receives the striking.
The utility model discloses a theory of operation and use flow: the utility model discloses adjust the parcel in the battery outer layer according to the big or small shape of battery, correspond the laminating with wear-resisting strip 2 and battery edge during the parcel, wear-resisting strip 2 when the laminating cover at the battery edge right angle empty storehouse 3 can be perfect fixed with the right angle edge joint of battery, wear-resisting strip 2 has then thickened the thickness of battery edge rete, thicken the protection between PC membrane and sharp battery edge, prevent that the PC membrane from suffering the cutting and breaking, and cover the right angle empty storehouse 3 of 2 inside wear-resisting strips on battery surface then form the air chamber, can play fine cushioning effect when the battery receives the striking.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
