Abstract

The invention discloses a battery. The battery comprises a pole piece, a diaphragm, a cover plate, a tab and a central tube, the pole piece and the diaphragm are wound together to form a roll core, the roll core is provided with a central hole, the cover plate comprises a pole column, one side of the tab is connected with the pole piece, the central tube is located in the central hole, the pole column at least partially extends into the central tube, and a pressing plate and an elastic component are arranged in the central tube. The pressing plate abuts against the elastic component, the other side of the tab is bent and tightly attached to the pressing plate, the elastic component exerts elastic acting force on the pressing plate, and the tab is tightly attached to the pole through the pressing plate. According to the battery provided by the invention, the pressing plate enables the tab and the pole to be tightly attached under the action of the elastic force of the elastic component, so that the operation convenience of external electric connection of the shell is realized, the central tube effectively isolates the welding area of the tab and the pole from the roll core, and short circuit caused by contact of the tab and the roll core is avoided.

Description

technical field [0001] The invention relates to the technical field of batteries. Background technique [0002] In the interior of the existing battery, the positive tab after bending is easily attached to the winding core, but not attached to the positive post. The bent negative electrode lug is easily attached to the core, but not attached to the negative pole. In this way, a short circuit is easily formed inside the battery. [0003] Therefore, there is a need to provide a battery that at least partially solves the above-mentioned problems. Contents of the invention [0004] A series of concepts in simplified form are introduced in the Summary of the Invention, which will be further detailed in the Detailed Description. The summary of the invention in the present invention does not mean to limit the key features and essential technical features of the claimed technical solution, nor does it mean to try to determine the protection scope of the claimed technical soluti...
