Abstract
The utility model belongs to the technical field of a battery, and discloses an internal series connection type lithium battery which comprises a battery shell and electric core unit bodies, wherein the electric core unit bodies are connected with one another in series; and insulating pieces are arranged among the electric core unit bodies. The internal series connection type lithium battery has the characteristics of being good in safety performance, high in service voltage and small in size.
Description
Technical field
The utility model relates to field of batteries, relates in particular to the in-line battery structure of a kind of volume in-core.
Background technology
Present lithium-ion battery monomer voltage safe in utilization is limited, people for improve lithium battery voltage, just series connection between the battery is used, each battery in parallel all is an absolute construction because of each volume core, though the high rate capability of battery is increased but because the increase of inert matter, the energy density of battery also descends thereupon.And this lithium battery group use is also dangerous, has made volume big.
Summary of the invention
It is good that technical problem to be solved in the utility model provides a kind of security performance, working voltage height, the interior tandem lithium battery that volume is little.
For solving the problems of the technologies described above, the utility model by the following technical solutions: in-line lithium battery in a kind of, comprise battery case and electric core unit body, described electric core unit body is connected in series each other, is provided with insulating trip between the described electric core unit body.
Further, in above-mentioned in the in-line lithium battery, described electric core unit body comprises the negative plate of the positive plate that has anode ear, barrier film, band negative electrode lug, and electric core unit body is that the negative plate integral body by the positive plate that has anode ear, barrier film, band negative electrode lug stacks the back and reels and form; The anode ear of forming on the first electric core unit body positive plate of connecting mutually has lug glue; The negative electrode lug of forming on the end electric core unit body negative plate of connecting mutually has lug glue; The first electric core unit body negative electrode lug of forming series connection mutually links to each other with the anode ear of next electric core unit body, and an end electric core unit body anode ear of forming series connection mutually links to each other with the negative electrode lug of last one electric core unit body; The negative electrode lug that between the electric core unit body in centre that composition is connected mutually all is single electric core unit body links to each other with the anode ear of next electric core unit body, and its anode ear links to each other with the negative electrode lug of last one electric core unit body.
Further again: in above-mentioned in the in-line lithium battery, described electric core unit body integral body is cylindrical, taper, spindle, a kind of in square.Described battery case integral body is a kind of in flexible package shell, aluminum hull, the box hat.Described insulating trip is insulation spacer or insulation gummed paper.
Compared with prior art, above-mentioned interior in-line lithium battery comprises battery case and electric core unit body, and described electric core unit body is connected in series each other, is provided with insulating trip between the described electric core unit body.Be connected in series between electricity core unit body and the electric core unit body, so the working voltage height all is integrated in the housing between electric core unit body and the electric core unit body, so the overall cell volume is little, fail safe is also high.

Fig. 1 is the structural representation of two electric core unit body series connection in the present embodiment;
Fig. 2 is the expanded view after electric core unit body one is dissected;
Fig. 3 is the expanded view after electric core unit body two is dissected;
Wherein 1 battery case, 2 electric core unit bodies, 3 insulating trips, 4 anode ears, 5 positive plates, 6 barrier films, 7 negative electrode lugs, 8 negative plates, 9 lug glue.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with embodiment and accompanying drawing:
As Fig. 1-3, a kind of interior in-line lithium battery comprises battery case 1 and electric core unit body 2, and described electric core unit body is connected in series each other, is provided with insulating trip 3 between the described electric core unit body 2.Described electric core unit body 2 comprises positive plate 5, the barrier film 6 that has anode ear 4, the negative plate 8 of being with negative electrode lug 7; The anode ear of forming on electric core unit body one positive plate 5 of connecting mutually 4 has lug glue 9, as shown in Figure 2; The negative electrode lug of forming on electric core unit body two negative plates 8 of connecting mutually 7 has lug glue 9, as shown in Figure 3; The negative electrode lug 7 of electricity core unit body one links to each other with the anode ear 4 of electric core unit body two, and described electric core unit body 2 integral body are cylindrical, and battery case 1 integral body is columniform flexible package shell.
The step of making above-mentioned interior in-line lithium battery is as described below:
A, make battery pole piece by normal cylindrical battery technology;
The anode ear 4 of B, electric core unit body one positive plate 5 welding band lug glue 9, negative plate 8 welding do not have the negative electrode lug 7 of lug glue 9, as shown in Figure 2;
C, 5 welding of electric core unit body positive plate do not have the anode ear 4 of lug glue 9, the negative electrode lug 7 of negative plate 8 welding band lug glue 9, as shown in Figure 3;
D, two electric core unit bodies add that barrier film 6 forms electric core unit body by the mode of reeling, the negative electrode lug 7 of electric core unit body one anode ear 4 with electric core unit body two is welded together, between separate with pad or gummed paper 3;
E, encapsulate, fluid injection, operation such as change into by normal lithium ion battery production process again, finish whole electric core group and make.
Above-mentioned only is preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection range of the present utility model.
