Description
Technical field
The utility model relates to technical field of lithium batteries, refers in particular to a kind of battery anode slice of new structure.
Background technology
Lithium battery in the extensive use in stored energy power and digital battery field, in the urgent need to a large amount of high consistency monomer battery core, the consistency of guarantee battery pack.
Column structure lithium ion, require low internal resistance, high rate performance is excellent, high safety, long-life; Carry out a large amount of improvement battery pole piece configuration aspects people, guarantee electrokinetic cell performance requirement.Common power is as the battery roll core material strip (pole piece of power battery) of lug, and generally comprise the dressing district of a rectangular active material, arrange Liao Bo district outside dressing district, in Kong Bo district, the butt-joint of lug position arranges a lug; When lug is arranged on edge side or the centre position of pole piece; after making battery; usually can find, after long-time circulation, pole piece edge is because itself having certain toughness; after pole piece welding or charging are expanded; the empty paper tinsel of lug both sides of edges can be formed and cut print, empty paper tinsel position and dressing area edge more crisp and thin, lug cuts off pole piece situation and happens occasionally; thus cause battery core part, cause battery battery core fault and other potential safety hazards.
Utility model content
The utility model is to cut off for current lithium ion lug lug in battery anode slice the deficiency that empty paper tinsel position and dressing district cause the existence cutting off pole piece, and provides the battery anode slice of a kind of new structure overcome the above problems.
For achieving the above object, the utility model adopts following technical scheme:
A battery anode slice for new structure, described battery anode slice comprises the dressing district of a coating anode material, and described dressing district has connected paper tinsel position; On described empty paper tinsel position, welding arranges a lug, and described lug is sticked the protective tapes of insulator on the empty paper tinsel position of the one or both sides of butt-joint point.
Preferably, when described lug is connected to the edge side in dressing district, lug is at the protective tapes of the insulator that is sticked on the empty paper tinsel position of side, longer dressing district of butt-joint point.
Preferably, when described lug is connected to the centre position in dressing district, lug is sticked the protective tapes of insulator on the empty paper tinsel position of the both sides of butt-joint point.
The beneficial effects of the utility model are: the battery anode slice of new structure of the present utility model, and battery anode slice comprises the dressing district of a coating anode material, dressing district is arranged paper tinsel position; On empty paper tinsel position, welding arranges a lug, and described lug is sticked the protective tapes of insulator on the empty paper tinsel position of the one or both sides of butt-joint point; After formation battery roll core; the empty paper tinsel position of the one or both sides of butt-joint point is sticked the protective tapes of insulator; protection is formed to lug both sides of the edge; lug can not be there is cut off empty paper tinsel position and dressing district and cause the situation cutting off pole piece to occur, avoid battery core part and cause battery battery core fault and other potential safety hazards.

Embodiment
Below in conjunction with accompanying drawing 1-3, the utility model is further elaborated:
A battery anode slice for new structure, described battery anode slice comprises the dressing district 1 of a coating anode material, and described dressing district 1 has connected paper tinsel position 2; On described empty paper tinsel position 2, welding arranges a lug 3, and described lug 3 is sticked the protective tapes 4 of insulator on the empty paper tinsel position 2 of the one or both sides of butt-joint point 31.
When lug 3 is connected to the edge side in dressing district 1; lug 3 is at the protective tapes 4 (as shown in Figure 1) of the insulator that is sticked on the empty paper tinsel position 2 of side, longer dressing district 1 of butt-joint point 31; in this case; after coiled strip; lug 3 is easily formed in side, nearly longer dressing district 1 and cuts print; cut sky paper tinsel position 2 and dressing district 1, at the protective tapes 4 of lug 3 at the insulator that is sticked on the empty paper tinsel position 2 of side, longer dressing district 1 of butt-joint point 31, play effective protection.
When lug 3 is connected to the centre position in dressing district 1, after coiled strip, lug 3 is easily formed in side, both sides and cuts print, therefore needs lug 3 to be sticked on the empty paper tinsel position 2 of the both sides of butt-joint point 31 protective tapes 4 (as shown in Figure 2) of insulator.
Certainly; the protective tapes 4 of one whole piece can also be directly set on empty paper tinsel position 2; directly by lug 3 butt-joint on empty paper tinsel position 2; due to butt-joint effect; can at butt-joint point 31 breakdown protection adhesive tape 4; lug 3 is fully contacted with empty paper tinsel position 2, thus is formed in lug 3 both sides and realizes protective tapes 4, effectively carry out protection battery roll core (as shown in Figure 3).
The battery anode slice of new structure of the present utility model; after formation battery roll core; the empty paper tinsel position 2 of the one or both sides of butt-joint point 31 is sticked the protective tapes 4 of insulator; protection is formed to lug 3 both sides of the edge; lug 3 can not be there is cut off empty paper tinsel position 2 and dressing district 1 and cause the situation cutting off pole piece to occur, avoid battery core part and cause battery battery core fault and other potential safety hazards.
The above embodiment, just preferred embodiments of the present utility model, be not limit the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should be included in the utility model patent claim.
