Description
Technical field
The utility model is related to a kind of lithium battery electrode leadings of high charge-discharge magnification.
Background technology
Lithium battery is a kind of environmentally protective battery, does not generate the poisonous and harmful heavy metallics element such as any lead, mercury, cadmium, because
And it is more and more widely used.Common lithium battery has cylindrical type and square, and inside battery uses helically wound structures,
It is formed with a kind of polyethylene film isolated material very fine and that permeability is very strong in positive and negative pole spacing；Anode include by
Cobalt acid lithium（Or nickle cobalt lithium manganate, LiMn2O4, LiFePO 4 etc.）And the current collector of aluminium foil composition；Cathode is by graphitized carbon
The current collector composition of material and copper foil composition, battery are interior filled with organic electrolyte solution.It can also be by special metallization
Film replaces aluminium foil and copper foil.
The lead-out mode of electrode of lithium cell generally using lug mode, welds on current collector（Or other connections
Mode）There is the lug of respective metal material, the lug is as output current or receives the electrode of charging current, and this lug is
Some from current collector locally extracts, and smaller contact surface has negative shadow to several important indicators of lithium battery
It rings：Internal resistance, charge-discharge magnification.On the other hand, if metallized film collector, also there is the problem for being difficult to draw lug.
Utility model content
The purpose of this utility model is to provide a kind of lithium battery electrode leading of high charge-discharge magnification, which can solve
The internal resistance of the problem of certainly film current collector extraction electrode is difficult, effectively reduction battery, raising charge-discharge magnification, and simple in structure,
It is at low cost.
Technical solution is used by the utility model solves its technical problem：
A kind of lithium battery electrode leading of high charge-discharge magnification, plus plate current-collecting body are staggered with negative current collector, anode
The protruding end of collector is located at the side of lithium battery, and the protruding end of negative current collector is located at the opposite side of lithium battery；The anode
The protruding end deposition of collector has positive gilding layer, and positive gilding layer is electrically connected with plus plate current-collecting body, and the protruding end of negative current collector sinks
Product has negative gilding layer, and negative gilding layer is electrically connected with negative current collector.
Further, the positive gilding layer is aluminium alloy, and it is copper alloy or nickel alloy to bear gilding layer.
The beneficial effects of the utility model are：
First, gilding layer is big as the connection area of extraction electrode and collector, and internal resistance is small；
2nd, it improves lug and holds current-carrying ability, so as to improve the charge-discharge magnification of battery；
3rd, by positive gilding layer and negative gilding layer, the positive electrode and negative electrode of lithium battery are drawn respectively, convenient for subsequently welding,
It is difficult to solve the problems, such as that film current collector electrode is drawn；
4th, positive gilding layer is located at the different sides of lithium battery with negative gilding layer respectively, avoids the occurrence of traditional unilateral extraction pole
Positive and negative electrode caused by ear mode connects short circuit problem, without insulator cap is in addition added, simplifies structure and technique.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of lithium battery electrode leading of high charge-discharge magnification of the utility model offer, plus plate current-collecting body 1,
Diaphragm 3 and negative current collector 2 successively intersecting or winding；Plus plate current-collecting body 1, diaphragm 3 and negative current collector 2 overlap
Region be battery chemistries reaction active region, the protruding end of plus plate current-collecting body 1 is located at the side of lithium battery, negative current collector
2 protruding end is located at the opposite side of lithium battery；There is positive gilding layer in the protruding end of plus plate current-collecting body 1 as effective join domain deposition
4, positive gilding layer 4 is electrically connected with each plus plate current-collecting body 1, and the protruding end of negative current collector 2 has as effective join domain deposition
Negative gilding layer 5, negative gilding layer 5 are electrically connected with each negative current collector 2.
Negative current collector 2 is only protruding with due to being only protruding with plus plate current-collecting body 1, opposite side in the side of lithium battery, so
When depositing gilding layer, it will not only cause the short circuit between positive and negative anodes collector, but also each layer of collector can be connected, point
Extraction electrode is not formed.
As preference, positive gilding layer 4 is aluminium alloy or the metal alloy for having close potential with aluminium, negative gilding layer 5 is adopted
With copper alloy, nickel alloy or other alloys with appropriate potential.Gilding layer is prepared using metal spraying technique.
By positive gilding layer 4 and negative gilding layer 5, the positive electrode and negative electrode of lithium battery are drawn respectively, convenient for subsequently welding pole
Ear solves the problems, such as that film current collector electrode draws difficulty, meanwhile, because the contact area of gilding layer and collector is big, energy
Current load is enough improved, reduces internal resistance, promotes charge-discharge magnification；Since positive gilding layer 4 and negative gilding layer 5 are located at lithium battery respectively
Not homonymy so that electrode is also drawn from the both sides of lithium battery respectively, caused by avoiding the occurrence of traditional unilateral extraction electrode mode
Positive and negative electrode connects short circuit problem, without insulator cap is in addition added, simplifies structure and technique.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation；Any those skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above is made technical solutions of the utility model many possible changes and modifications or is revised as
The equivalent embodiment of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification made to the above embodiment, equivalent replacement, equivalence changes and modification, still fall within this practicality
In the range of the protection of new technique scheme.
