Embodiment Construction

[0024] 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, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] 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.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to a lithium battery packaging shell. The lithium battery packaging shell comprises a barrel, as well as a negative electrode cap, a positive electrode cap, a connecting piece and a positive electrode current collector which are arranged on the barrel, wherein the barrel comprises a first end part and a second end part; the first end part is in threaded connection with the negative electrode cap; the second end part is in threaded connection with the positive electrode cap; the connecting piece is accommodated in the barrel and is pressed against the positive electrode cap; the connecting piece comprises a first connection part and a second connection part; a continuous annular stepped groove is formed by an inner wall of a lower end of the second connection part andan inner wall of an upper end of the first connection part to accommodate the positive electrode current collector. The lithium battery packaging shell is in threaded connection with the negative electrode cap and the positive electrode cap through the barrel, and the cylinder is detachably assembled together with a battery core, so that customization of equipment for manufacturing and machining alaboratory-stage battery is avoided, the research and development process is simplified greatly, the research and development period is shortened, and the equipment purchasing and customizing cost islowered.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a lithium battery packaging casing and a lithium battery used for laboratory research and development. Background technique [0002] With the development of science and technology, the energy crisis has become increasingly prominent. Lithium batteries are a new type of energy storage energy. As a new type of green and environmentally friendly energy storage components, they have the advantages of environmental protection, high energy density, long service life, and wide application. , It is widely used in emerging fields such as electronic technology, electric vehicle energy storage, automobile starting, military industry, and aerospace. [0003] At present, the current structural design of cylindrical lithium batteries is mostly the structure of 18650 and 26650 lithium batteries, and its manufacturing process is roughly divided into production, assembly, formation, and packaging. The e...
