Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a small lithium battery that is easy to assemble and disassemble. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become the mainstream. A search revealed that patent application number 202420465820.7 discloses a small lithium battery that is easy to disassemble and assemble. The battery includes a casing, an installation groove on the top of the inner wall of the casing, limit grooves on both sides of the inner wall of the installation groove, and a positioning groove on the bottom of the inner wall of the casing. A return spring is installed inside the positioning groove, and an installation plate is installed on top of the return spring. A lithium battery structure is disposed between the positioning groove and the installation groove. This invention utilizes the installation groove to allow the lithium battery body to be inserted into the casing and abut against the bottom mounting plate. Then, the lithium battery body is rotated 90° to engage the limit strip with the bottom of the installation groove, thereby enabling quick disassembly and replacement of the lithium battery body. The aforementioned application documents achieve rapid assembly and disassembly of cylindrical lithium batteries through the configuration of various components. However, in existing technologies, many small lithium battery boxes require multiple rectangular lithium batteries to be precisely filled into the box one by one during assembly, followed by electrical connection of the battery pack using connecting wires. This operation is not only complex and requires a high level of skill and precision from the operators, but also poses safety hazards such as poor connections and short circuits due to manual operation, resulting in low overall assembly efficiency. Furthermore, when a single lithium battery in the battery pack experiences performance degradation or failure, the lack of a convenient disassembly and assembly structure requires maintenance personnel to spend a significant amount of time disassembling the connecting wires, removing the faulty battery, and reconnecting the circuit. This inefficiency severely restricts the rapid maintenance and upgrading of the equipment, making it difficult to meet the market's urgent demand for efficient assembly and convenient maintenance of small lithium battery boxes.

[0003] Therefore, we propose a small lithium battery that is easy to install and remove. Utility Model Content
