Abstract

The invention belongs to the technical field of battery manufacturing, in particular to a bullet-shaped battery which comprises a battery shell. The battery shell comprises a lower cavity and an uppercavity, and the interior of the battery shell can be arranged by adopting various schemes. One scheme is that a roll core wound by a rectangular pole piece is arranged in the upper cavity, and the lower cavity is filled with electrolyte, so that the characteristics of long service life and high multiplying power are realized. The other one scheme is that a roll core structure which is formed by winding a trapezoidal or quasi-trapezoidal pole piece and is flat at the upper part and convex at the lower part, is adopted, so that the design capacity of the battery core is increased. The battery core of the bullet-shaped battery is suitable for small wireless Bluetooth earphones, the service life of the product is prolonged or the service life of a product battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a bullet-shaped battery cell. Background technique [0002] At present, small wireless Bluetooth headsets have various shapes. In order to adapt to the shape of the product, the space for storing the battery is not necessarily a square hexahedron, such as a cuboid or a cube, but may also be a polyhedron with a trapezoidal cross-sectional shape. If ordinary rectangular batteries are still used in special-shaped spaces, there will be the following disadvantages: rectangular batteries cannot make full use of the reserved space for storing batteries, resulting in low design capacity of batteries and short standby time of equipment. [0003] Therefore, there is a need for a battery cell that can better adapt to the shape of the product and at the same time increase the design capacity of the battery cell. Contents of the invention [0004] In order to solve the abov...
