Description
Technical field
The utility model relates to a kind of polar ear structure of polymer Li-ion battery.
Background technology
Existing polymer Li-ion battery, there is multiple anode ear and negative electrode lug, anode ears all after coiling welds together, all negative pole lug weldings together, but, during welding, easily cause solder joint out-of-flatness, affect the overall performance of battery, therefore, be necessary the polar ear structure designing a kind of polymer Li-ion battery.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of polar ear structure of polymer Li-ion battery, and the polar ear structure of this polymer Li-ion battery has structure feature cleverly, and lug is easy to weld together.
The technical solution of utility model is as follows:
A polar ear structure for polymer Li-ion battery, multi-disc lug (2) is arranged on the upper side edge place of pole piece (1), and lug is connected with the substrate layer of pole piece; Here it is an entirety that connected refers to originally, and both metal materials, conducts during use.
Along the longitudinal direction of pole piece, the spacing of adjacent lug increases gradually, and when pole piece coiling completes, multi-disc lug is stacked together;
Lug is docked by lug epimere and lug hypomere (3) and forms; Lug epimere is square, and lug epimere is provided with multiple circular hole; Multiple circular hole is the array layout of multiple lines and multiple rows;
Lug hypomere is the isosceles trapezoid that bottom width is greater than top width.
Described pole piece is positive plate, and described lug is anode ear.
Described pole piece is negative plate, and described lug is negative electrode lug.
The one or both sides of lug are provided with and help layer.
The equal diameters of circular hole, the diameter of circular hole is 0.4-0.8mm.
The diameter of circular hole is 0.5mm.
Beneficial effect:
The polar ear structure of polymer Li-ion battery of the present utility model, arranges multiple circular hole (being conducive to for scolding tin water conservancy diversion) at lug epimere, helps the use of layer in addition, be convenient to Multilayer pole ear and weld together, avoid the loose contact that rosin joint causes.In addition, lug hypomere is isosceles-trapezium-shaped, and tension force is large, and anti-pull performance is good, effectively can improve the fastness of lug, and therefore, this extreme ear structure is simply ingenious, is easy to promotion and implementation.
