Abstract
The utility model relates to a lithium battery electrode, in particular to a combined lithium battery with welded tabs. The combined lithium battery comprises a battery shell and cells, and is characterized in that: the lithium battery is assembled by more than two cells in parallel, and tabs of same electrodes of the cells are respectively welded together by ultrasonic waves; the welded electrodes are connected with a pair of soft package tabs, and a battery shell made of an aluminum plastic film is wrapped outside the cells; an electrolyte is injected in each cell, and a membrane layer between a cathode and an anode is clamped in a winding cell; and an electric insulation membrane layer is wrapped outside each cell, and a high-temperature protective adhesive tape is adhered to a tab welding part. Compared with other lithium batteries, the combined lithium battery with the welded tabs is convenient for assembly and top side sealing, the production cost is reduced, and simultaneously, a plurality of cells are arranged in parallel to reduce the internal resistances of the cells, and the power supply capacity of a product and the safety in use can be improved.
Description
Technical field
The utility model relates to a kind of electrode of lithium cell, specifically is a kind of combination lithium battery of lug welded type.
Background technology
In the lithium battery industry, common lithium battery is an electric core, generally is rolling up a pair of both positive and negative polarity and barrier film on the inner core of battery, then through in cylinder or the square container.Traditional battery since battery pole ear be welded on the pole piece, battery pole ear and battery pole piece to be connected area little, contact resistance is big, causes the internal resistance of cell big, therefore is not suitable for as multiplying power discharging battery greatly.
Summary of the invention
The purpose of the utility model exactly in order to solve shortcoming of the prior art, and has designed a kind of combination lithium battery that adopts the lug welded type.
The utility model is realized through following technical scheme: a kind of combination lithium battery of lug welded type; Comprise battery case and electric core; Said lithium battery is by plural electric core parallel connection assembling; The lug of the identical electrodes of electricity core is connected together through supersonic welding respectively, and the electrode after the welding picks out a pair of Soft Roll lug, and the outside of electric core is surrounded by the battery case of aluminum plastic film.
Said each electric in-core is marked with electrolyte, in the electric core of reeling, accompanies the membrane layer between the both positive and negative polarity.
The outside of said each electric core all is surrounded by one deck electrical insulating material barrier film, and the lug weld posts the high temperature protection adhesive tape.
The beneficial effect of this programme can be learnt according to above-mentioned; Because above-mentioned lithium battery is by a plurality of electric core parallel connection assemblings; The lug of the identical electrodes of electricity core is connected together through supersonic welding respectively, and the electrode after the welding picks out a pair of Soft Roll lug, and the external packets of electric core is wrapped with battery case and seals at the top.Compare with other lithium batteries, be convenient to assembling, top side envelope, reduce production costs, a plurality of electric core parallel connections simultaneously can reduce electric in-core resistance, the fail safe of the power supply capacity that can improve product when using.The utility model cost of manufacture is low, makes simply, is applicable to the batteries of various different sizes, has good application and promotional value, compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, battery case, 2, pad, 3, lug, 4, electric core.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, according to accompanying drawing the utility model embodiment is described further below:
Embodiment: a kind of combination lithium battery of lug welded type; Comprise battery case 1 and electric core 4; Said lithium battery is by two electric core 4 parallel connection assemblings, and the lug 3 of the identical electrodes of electric core 4 is connected together through supersonic welding respectively, and the electrode after the welding picks out a pair of Soft Roll lug 3; Behind the battery case 1 of outer wrap aluminum plastic film of electricity core 4, the side of packaged battery and top successively.Be marked with electrolyte in each electric core 4, in the electric core 4 of reeling, accompany the membrane layer between the both positive and negative polarity.The outside of each electric core 4 all is surrounded by one deck electrical insulating material barrier film, and the lug weld posts the high temperature protection adhesive tape.
The utility model is not limited in above-mentioned embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to the protection range of the utility model.
