Abstract
The utility model relates to the technical field of a lithium battery, in particular to a 9V square lithium battery package shell, comprising a battery shell for packing and forming a battery cell inthe lithium battery, the top part of the battery shell is connected with a cover board, a battery terminal is led out on the cover board, a liquid injection port is arranged at the bottom part of thebattery shell, and the battery shell is formed by injection-molding a metal shell in a mold. Plastics is made of acrylonitrile butadient styrene, polypropylene, polyethylene, high-density polyethyleneor copolymers, the metal shell is punched by metal plates such as aluminum or stainless steel and is processed in a polarization way. The plastic inner layer of the battery can form three small lattices required in the battery assembly production, so as to completely separate the battery cells and be beneficial to placement and sealing of the battery cells. The metal shell is commonly injection-molded at the periphery of the plastic inner layer, thereby effectively reducing the problems that the existing battery electrolyte with a plastic shell is easy to leak and water vapor is easy to infiltrate, increasing the intensity and safety of the battery and effectively improving the performance and the service life of the battery.

Technical field
The utility model relates to 9V quadrate lithium battery technical field, is specifically related to the improvement of 9V quadrate lithium battery shell structure.
Background technology
The 9V lithium battery is a kind of common battery kind, and its capacity, life-span and fail safe have higher requirement.
The principle of lithium battery requires electrolyte to have higher permeability.But for preventing the seepage of electrolyte outside battery container, existing 9V lithium battery housing adopts steel metal-back or aluminum metal shell to encapsulate substantially.But adopt the metal shell encapsulation to have the drawback of blast easily, development along with injection molding technology, also have part 9V lithium battery to come battery is carried out moulding encapsulation by injection moulding all-plastic shell, reduce the danger of blast, to infiltrate the performance that is caused bad because of solution leakage and steam but brought.
The disclosed lithium ion battery package casing of China's ZL99244912.X patent " a kind of package casing of lithium ion battery ", it has adopted plastic film and aluminium foil to form the scheme that shell or plastic casing and enclosing cover constitute shell.But its essence only is simple material replaces, and also exists easily to puncture or the danger of leakage.
U.S. Patent number be the patent documentation of US5134046 disclosed be to adopt the injection molded method to come the square 9V battery case of injection moulding, battery case inside is divided into three cells, per three electric cores are put into wherein, after the ultrasonic bonding sealing three electric cores of list are connected into the 9V lithium battery, outside the coated metal shell.The method of coated metal shell behind this employing injection molded method production battery case, though reduced the ratio that solution leakage and steam infiltrate, but complex process, high to the production equipment requirement, make the manufacturing cost height, after its long storage time, electrolyte still can infiltrate from the battery plastics shell, and ooze out from slit, metal shell edge, moisture also can enter the space between metal-back and plastic housing in the while environment, and infiltrate inside battery by plastics, the useful life of influence battery performance, reducing battery.
The utility model content
Technical problem to be solved in the utility model provides a kind of solution leakage and steam of can reducing and infiltrates, can prevent puncturing again the blast protection and the 9V quadrate lithium battery encapsulating housing of long service life.
For solving the problems of the technologies described above, realize that the technical solution of the utility model is:
Design a kind of 9V quadrate lithium battery encapsulating housing, comprise battery case with lithium battery interior electricity core encapsulated moulding, the battery case top is connected with cover plate, lead to battery electrode column on the cover plate, battery case bottom is provided with liquid injection port, and described battery case is put into the mould injection moulding by the outer layer metal shell and formed inner plastic and constitute.
As the improvement of such scheme, described inner plastic is to be made by acrylonitrile butadient styrene or polypropylene or polyethylene or high density polyethylene (HDPE) or the copolymer between them, and described outer layer metal shell is aluminum hull or stainless steel case.
In the such scheme, the thickness range of battery case is 0.5mm～1.5mm, and the thickness range of its outer layer metal shell is 0.05mm～0.50mm.
The improved 9V quadrate lithium battery of the utility model encapsulating housing, its battery case is put into mold injection by skin polarization metal-back and is formed.Inner plastic can form the desired assembling shape of battery Assembling Production, putting into of electric core can be separated, is beneficial to electric core fully; Liquid injection port is established in the bottom, makes things convenient for fluid injection and sealing; The metal-back that periphery has injection moulding to inlay has not only reduced common leakage of existing plastic casing battery and steam and has infiltrated problem, has increased the intensity of battery again.
Description of drawings
Accompanying drawing 1 is to adopt cell integrated cross section structure schematic diagram of the present utility model;
Accompanying drawing 2 is enlarged diagrams of the A portion of accompanying drawing 1;
Embodiment
The purpose of this utility model is to adopt a kind of lithium battery encapsulating housing of new structure, and this encapsulated shell structural can reduce the seepage of battery electrolyte and the infiltration of steam, the useful life of effectively improving battery.The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1,2, a kind of 9V quadrate lithium battery encapsulating housing, this lithium battery housing is by with the battery case 1 of lithium battery interior electricity core 5 encapsulated mouldings be connected battery case top blind flange 2 and constitute.Cover plate is made of middle cover and loam cake.Loam cake leads to battery electrode column 3, and middle cover and battery case 1 adopt supersonic welding to be connected together.The battery case bottom is provided with liquid injection port 4, and plunger is by ultrasonic bonding or injection moulding sealing means sealing liquid injection port.
The battery case of the 9V quadrate lithium battery encapsulating housing in the present embodiment is outer layer metal shell 12 to be put into mold injection formation inner plastic 11 form.The inner plastic internal layer can be acrylonitrile (A) butadiene (B) styrene (S) copolymer (ABS) or polypropylene (PP) or polyethylene (PE) or high density polyethylene (HDPE) (HDPE) or the copolymer between them, and the outer layer metal shell can be metal-backs such as aluminum hull or stainless steel case.The outer layer metal shell is handled through chemical polarization, makes metal-back and melting plastics that good coupling be arranged
For under the certain condition of battery overall dimension, increase the capacity of battery as much as possible, the thickness range of the battery case 1 in the present embodiment is advisable at 0.5mm～1.5mm, and its outer layer metal shell 12 thickness ranges are 0.05mm～0.50mm.
