Preferably, the bottom of the combined cover cap is of an arc structure, and grooves with V-shaped structures are formed in two ends of the bottom of the combined cover cap in a chiseled mode.

Preferably, the top of the combined cover cap is fixedly provided with an electrode connector.

Preferably, the positive electrode full tab and the negative electrode full tab are manufactured by adopting a continuous coating process and spirally winding, and the end face of the positive electrode full tab is sprayed with insulating glue.

Preferably, the metal shell is of a cylindrical structure, and the size of the metal shell is matched with that of the winding core.

Preferably, the metal shell and the combined cap electrode joint are in an open circuit state, and the metal shell is not electrified.

The utility model has the advantages that:

the utility model discloses be provided with positive negative pole full utmost point ear, combination block, metal casing, the bottom of combination block is the arc structure, is convenient for better and positive negative pole full utmost point ear be connected, through adjusting the negative pole piece well and press the continuous coating of process length, and middle incessant, one side is left blank as utmost point ear to the effectual internal resistance that reduces battery itself has solved current chargeable cylindrical battery charging efficiency slow, monomer capacity is low, the internal resistance is big, easy short circuit scheduling problem.

Description of the drawings:

for ease of illustration, the invention is described in detail by the following detailed description and accompanying drawings.

Fig. 1 is a schematic view of the installation structure of the present invention;

FIG. 2 is a schematic structural view of the roll core and the metal shell of the present invention;
