Problems solved by technology

[0003] However, due to the small size of some micro-batteries, the maximum size is usually less than 10mm, and the structural strength of the pole piece unit is low, so it is difficult for the pole piece unit to form a roll structure with a set shape when winding, and the good product of the battery rate reduction
[0004] In addition, the shell and cap of the micro-battery are very small, and when the current collector is welded, the working space is limited, and it is difficult to weld it in place

Abstract

The invention discloses a battery. The battery comprises a cell, the cell includes a pole piece unit and a core post, the pole piece unit is wound on the outside of the core post, the core post includes at least one electrical connection, the electrical connection includes an elastic element, a main body portion and a conductor portion at one end of the main body portion, wherein the elastic element is configured to form a preelastic force on the conductor portion so as to bring the conductor portion into contact with a device other than the cell, and a current collector located inside the electrode plate unit is connected to the core post and is conductive to the conductor portion.

Description

technical field [0001] The present invention relates to the technical field of energy storage equipment, and more specifically, to a battery. Background technique [0002] Some batteries, especially lithium-ion batteries, typically include a case, a cap, and cells. The electric core is located in the inner cavity of the casing and is insulated from the casing. The cap fits over the open end of the housing. The battery core is made by winding the pole piece unit. The pole piece unit includes a positive pole piece, a diaphragm and a negative pole piece bonded together. The current collector of the positive electrode sheet is welded to the cap. The cap forms the positive terminal of the battery. The current collector of the negative electrode sheet is welded to the casing. The bottom of the case acts as the negative terminal of the battery. [0003] However, due to the small size of some micro-batteries, the maximum size is usually less than 10mm, and the structural stre...
