To achieve the goals above, the utility model provides a kind of anode ear, including lug aluminium flake ontology, the lug The one end of aluminium flake ontology far from the battery core is welded with copper sheet, the lug aluminium flake sheet between the copper sheet and the battery core Body is equipped with gel, and tin layers are provided on the copper sheet.
Preferably, the copper sheet is arranged in the front of the lug aluminium flake ontology and/or reverse side.
Preferably, the distance between the upper end of the gel and the lower end of the copper sheet are 0.3mm-0.7mm.
Preferably, the thickness of the tin layers is 0.01-0.1mm.
Preferably, the thickness of the copper sheet is 0.1-0.3mm.
Preferably, the gel is three layers.
Preferably, the gel includes nonwoven layer and the resin layer positioned at the nonwoven layer two sides.
The utility model additionally provides a kind of battery core, which includes negative electrode lug and above-mentioned anode ear.
The utility model additionally provides a kind of poly-lithium battery, which includes above-mentioned battery core.
Compared with prior art, the lug aluminium flake ontology of the utility model is provided with copper sheet, greatly improved with aluminium Matter is not easy the performance of upper tin as the anode ear of material, and improves the transmittability of the electric current of anode ear, and applicable high current is put Electricity is also provided with tin layers on copper sheet, and plating metallic tin on the unassembled anode ear sheet body on lithium ion battery avoids Tin is voluntarily gone up by lithium ion battery manufacturer, accelerates the production efficiency of lithium ion battery manufacturer finished product, simultaneously, moreover it is possible to keep away Exempt to assemble the problems such as upper Xi Shiyin welding high temperature causes battery core leakage again after on lithium ion battery by anode ear sheet body.
Description of the drawings
Fig. 1 is the structural schematic diagram of the poly-lithium battery of the utility model.
Specific implementation mode
For the technology contents that the present invention will be described in detail, construction feature, the effect of realization, below in conjunction with embodiment and coordinate Attached drawing is explained in detail.
Referring to FIG. 1, the poly-lithium battery 10 of the utility model, including battery core 20, anode ear 30 is set in battery core 20 With negative electrode lug 40, negative electrode lug 40 and anode ear 30 are located at the upper end of battery core 20, and are located at the same side;Specifically, anode ear 30 wraps Lug aluminium flake ontology 31 is included, 31 one end far from battery core 20 of lug aluminium flake ontology is welded with copper sheet 33, and the thickness of copper sheet 33 is 0.1-0.3mm, for example, the thickness of copper sheet 33 can be 0.1mm, 0.2mm, 0.3mm, the lug between copper sheet 33 and battery core 20 Aluminium flake ontology 31 is equipped with gel 35, and tin layers are provided on copper sheet 33(It is not shown).The thickness of tin layers is 0.01-0.1mm, than Such as, the thickness of tin layers can be 0.01mm, 0.05mm, 0.1mm, by without assigned in the anode ear 30 on lithium ion battery Sheet body setting tin layers can avoid lithium ion battery manufacturer voluntarily upper tin, accelerate lithium ion battery manufacturer finished product Production efficiency, meanwhile, also avoid after by the assembly of anode ear 30 on lithium ion battery that upper Xi Shiyin welding high temperature causes again The problems such as 20 leakage of battery core;The front or back in lug aluminium flake ontology 31 can be arranged in copper sheet 33, can also be arranged simultaneously The obverse and reverse of lug aluminium flake ontology 31, the distance between the upper end of gel 35 and the lower end of copper sheet 33 are 0.3mm- 0.7mm, for example, the distance can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm;Gel 35 is three layers, specifically Ground, gel 35 include nonwoven layer and the resin layer positioned at nonwoven layer two sides, improve the air barrier effect of gel 35 Fruit and anticorrosive intensity.
