Problems solved by technology

Button batteries have the characteristics of high energy density, good storage performance, small self-discharge capacity, and long life. However, for traditional button batteries, in order to increase the capacity of the battery to enhance its own battery life, the thickness of the button battery is usually caused. and volume increase; when in order to reduce the thickness and volume of the button battery, the capacity and endurance of the battery are usually reduced
Therefore, the traditional button battery cannot take into account its large capacity and small size at the same time.

Embodiment Construction

[0028] 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.

[0029] 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 "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The invention relates to a covering assembly and a battery. The covering assembly is used for covering a shell, provided with am accommodating cavity, of the battery and comprises a top cover, the top cover is used for being connected with the shell and covering the accommodating cavity, the top cover is provided with a top face arranged back to the accommodating cavity, and the top face is sunken towards the containing cavity to form a counter bore; the covering assembly also comprises a positive plate which is arranged on the top cover, the counter bore is used for accommodating the positive plate, the positive plate is provided with an upper surface arranged back to the accommodating cavity, and the upper surface is flush with the top surface; or the upper surface is closer to the accommodating cavity relative to the top surface. Therefore, the thickness of the positive plate does not increase the thickness of the battery, so that the thickness of the battery can be reduced, and the volume of the battery is reduced to realize miniaturization. Meanwhile, the structure can ensure that the accommodating cavity has large enough volume, and finally ensures that the battery can simultaneously consider two core parameters of large capacity and small volume, and the improvement of one parameter does not take the cost of sacrificing the other parameter.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a cover assembly and a battery containing the cover assembly. Background technique [0002] Portable electronic devices and smart wearable devices are widely used in people's production and life. The above-mentioned devices have a trend of becoming more and more miniaturized. As the core component that provides energy for the normal operation of the above-mentioned devices, the battery also requires the design of the battery More miniaturization, so the button battery with small volume came into being. Button batteries have the characteristics of high energy density, good storage performance, small self-discharge capacity, and long life. However, for traditional button batteries, in order to increase the capacity of the battery to enhance its own battery life, the thickness of the button battery is usually caused. and volume increase; when in order to reduce the thickness and ...
