Technical Field

The invention relates to the field of batteries, in particular to a battery.

Background

In the micro battery manufacturing process, often need weld the utmost point ear on protection shield and the electric core, like in the bluetooth headset battery manufacturing process, need weld utmost point ear and protection shield on the electric core together, however, current protection shield need brush tin cream earlier, paste the nickel piece, then just can carry out spot welding with the utmost point ear of electric core, whole technology is loaded down with trivial details, the process is troublesome, the cost is higher, moreover, the battery that produces like this is whole thick, is unfavorable for the ultra-thin processing of battery.

Disclosure of Invention

The invention provides a battery, which solves the problems of complex welding process, troublesome working procedure, higher cost and larger welding thickness of a lug and a protective plate of a battery cell in the prior art.

In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a battery, includes electric core and protection shield be equipped with anodal utmost point ear and negative pole utmost point ear on the electric core, anodal utmost point ear with negative pole utmost point ear all with the protection shield is connected be equipped with anodal lead-out wire and negative pole lead-out wire on the protection shield, the protection shield contains PCB sheet layer, copper plate layer and welding layer in proper order, the welding layer is nickel coating or sinks the nickel coating, anodal utmost point ear with negative pole utmost point ear all with welding layer fixed connection.

Preferably, the positive electrode lug and the negative electrode lug are fixedly connected with the welding layer in a spot welding mode.

Preferably, a chip for controlling the protection plate is arranged on the protection plate.

Preferably, the chip 7 is disposed on one face of the PCB board layer.

Preferably, the overall shapes of the protection plate and the battery cell are both rectangular.

Preferably, the edges of the protection plate and the battery cell are arranged in parallel.

Preferably, the distance between the protective plate and the battery cell is 0.1mm-5.0 mm.

The invention has the following beneficial effects: compared with the existing design, the structure of the protection plate is changed, the protection plate is changed into a three-layer structure, namely a PCB plate layer, a copper plating layer and a welding layer, the welding layer is a nickel plating layer or a nickel sinking layer, and the positive pole lug and the negative pole lug are fixedly connected with the welding layer in a spot welding mode, so that the original layer number of the protection plate is reduced, the protection plate is thinner, and on the other hand, compared with the traditional design, the process is simpler and the production cost is greatly reduced because the number of brushing tin paste and sticking nickel sheets is reduced.
