Description
Technical field
The utility model is related to a kind of new type lithium ion battery, more particularly to a kind of using the polymer without the design of glue lug
Lithium ion battery.
Background technology
As the development of twentieth century microelectric technique, the equipment of miniaturization are increasing, power supply is proposed very high
Require.And widely using with the digital product such as product such as mobile phone, notebook computer, lithium ion battery exists with excellent performance
It is used widely in this kind of product, and progressively to other product applications development.Lithium ion battery is also entered therewith
The large-scale practical stage.Be able to application earliest is lithium Asia galvanic cell, in pacemaker.Due to lithium Asia battery from
Discharge rate is extremely low, and discharge voltage is very gentle.So that Pacemaker implantation human body Long-Time Service is possibly realized.Lithium-manganese cell typically has
Nominal voltage higher than 3.0 volts, is more suitable for making ic power, in being widely used in computer, calculator, wrist-watch.Present lithium
Ion battery is widely applied in mobile phone, notebook computer, electric tool, electric motor car, street lamp stand-by power supply, boat lamp, the little electricity of family expenses
On device, it may be said that be maximum application group.
The electrolyte that now current lithium ion battery is adopted is typically all liquid electrolyte, and liquid electrolyte is met water and can be divided
Solve hydrofluoric acid（HF）, so HF corrosion can only be just resistant to special aluminum plastic film, other encapsulating materials can not all meet requirement, this
Sample undoubtedly increased the cost of lithium ion battery, and encapsulation is difficult and security is relatively low, the damage ratio of discarded battery to environment
It is more serious.Accordingly, it would be desirable to a kind of new type lithium ion battery solves these problems.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of using the polymerization without the design of glue lug
Thing lithium ion battery, using semisolid gel-form solid polymer electrolyte, will not decomposite hydrofluoric acid, and packaging material will not be caused sternly
Heavy corrosion, the plastic foil that can use customization is capable of achieving encapsulation.
The purpose of this utility model is achieved through the following technical solutions：It is a kind of to adopt the polymerization without the design of glue lug
Thing lithium ion battery, including encapsulating material, several pole pieces and solder joint；Several described pole pieces include several positive plates and
Several negative plates, have anode ear on each positive plate, have negative electrode lug on each negative plate；If several described positive plates and
A dry negative plate alternates overlaps, and the anode ear of several positive plates after overlap and several negative plates after overlapping are born
Lug is each positioned at the both sides of pole piece, forms naked battery core；Described solder joint respectively welds together the anode ear that several are overlapped,
The negative pole lug welding that several are overlapped is together；Described encapsulating material is encapsulated in the pole piece after overlapping.
Described encapsulating material includes plastic foil.
The two sides of several described pole pieces scribbles electrolyte.
Described electrolyte is gel electrolyte.
The composition of described gel electrolyte includes fluoro lithium salts.
The beneficial effects of the utility model are：It is a kind of using without glue lug design polymer Li-ion battery, with
Lower advantage：1st, will not leakage, will not produce corrosive substance hydrofluoric acid product percent of pass improve 5%.2nd, the encapsulation of costliness is not adopted
Material aluminum plastic film, cost reduces by 15% -25%.3rd, manufacture craft is simplified, very high production efficiency shortens the production cycle.4、
Battery safety is improved, the risk of battery plus-negative plate and aluminum plastic film short circuit is reduced.5th, manufacture process is more environmentally friendly, Bu Huifen
Solve relatively low to the pollution of environment after hydrofluoric acid battery is discarded.
Description of the drawings
Fig. 1 is polymer Li-ion battery structure figure；
Fig. 2 is traditional lithium-ion battery structure chart；
In figure, 1- anode ears, 2- negative electrode lugs, 3- solder joints, 4- pole pieces, 5- plastic foils, 6- tabs, 7- aluminum plastic films.
Specific embodiment
The technical solution of the utility model, but protection domain of the present utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to described below.
As shown in figure 1, it is a kind of using without glue lug design polymer Li-ion battery, including encapsulating material, several
Pole piece 4 and solder joint 3；Several described pole pieces include several positive plates and several negative plates, have just on each positive plate
Lug 1, there is negative electrode lug 2 on each negative plate；Described several positive plates and several negative plates alternate overlap, overlap
The negative electrode lug 2 of several negative plates after the anode ear 1 and overlap of several positive plates afterwards is each positioned at the both sides of pole piece, is formed
Naked battery core；Described solder joint 3 respectively welds together the anode ear 1 that several are overlapped, and several negative electrode lugs 2 for overlapping are welded
It is connected together；Described encapsulating material is encapsulated in the surface of pole piece 4 after overlapping.
Described encapsulating material includes plastic foil 5.
The two sides of several described pole pieces 4 scribbles electrolyte.
Described electrolyte is gel electrolyte.
The composition of described gel electrolyte includes fluoro lithium salts.
As shown in Fig. 2 traditional lithium-ion battery can produce the hydrogen with severe corrosive because meeting water using liquid electrolyte
Fluoric acid, so encapsulating material must use expensive aluminum plastic film 7 to be packaged, and aluminum plastic film is by nylon layer, aluminium lamination and CPP
（The film of polyester third）Layer composition, if be placed directly against above positive and negative lug easily causing the short circuit of lithium battery both positive and negative polarity, so
Typically tab 6 can be sticked on positive and negative lug, positive and negative lug is directly isolated with aluminum plastic film, although can rise to a certain extent
To the effect of prevention lithium battery both positive and negative polarity short circuit, but the time permanent risk for still having a short circuit, and using tab and
Expensive aluminum plastic film also considerably increases the cost of lithium ion battery, and discarded battery also can cause very big pollution to environment.
The above is only preferred embodiment of the present utility model, it should be understood that the utility model is not limited to herein
Disclosed form, is not to be taken as the exclusion to other embodiment, and can be used for various other combinations, modification and environment, and
Can be modified by the technology or knowledge of above-mentioned teaching or association area in contemplated scope described herein.And this area
Change and change without departing from spirit and scope of the present utility model that personnel are carried out, then all should be in right appended by the utility model
In the protection domain of requirement.
