Problems solved by technology

[0003] However, the existing arc-shaped lithium battery cells are prone to rebound after being shaped, causing the problem of deformation of the arc-shaped lithium battery, thereby affecting the use of the arc-shaped lithium battery in products
Moreover, with the passage of time, the bending part of the arc-shaped lithium battery will gradually weaken the shaping effect due to stress and other reasons, which will cause the arc of the arc-shaped lithium battery to change and affect the use of the arc-shaped lithium battery.

Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention provides an arc-shaped battery cell with a shaping structure and an arc-shaped lithium battery. The arc-shaped battery cell with the shaping structure comprises a first shaping part and a second shaping part, the first shaping part and the second shaping part are both wound on the surface of the arc-shaped battery cell, the extension direction of the first shaping part is parallel to the radian direction of the arc-shaped battery cell, and a preset included angle is formed between the extension direction of the second shaping part and the radian direction of the arc-shaped battery cell. The first shaping piece and the second shaping piece intersect to form an intersection node, and the first shaping piece and the second shaping piece are connected to the intersection node. The arc-shaped battery cell with the shaping structure is relatively good in shaping effect, high in stability and relatively strong in shaping durability.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to an arc-shaped battery cell with a fixed structure and an arc-shaped lithium battery. Background technique [0002] Since the large-scale production of lithium-ion batteries was realized in the 1990s, it has rapidly occupied many battery fields due to its incomparable advantages such as small size, large capacity, non-toxic environmental protection, and long service life. on electronic products. With the renewal and development of science and technology, the market has higher and higher requirements for portable electronic products, and the requirements for its power supply have also increased accordingly. The space becomes an irregular shape. With the further development of electronic products, smart watches and smart bracelets are coming out one after another. Since they are worn on the wrist when in use, the equipped battery needs to be set according to the use ...
