[0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium ion batteries. However, due to their own high technical requirements;

[0003] Current lithium batteries are usually made by gluing several small batteries together with glue or tape and placing them in a casing, or winding them around and placing them in empty spaces between small batteries. When assembling or disassembling, the former is difficult to disassemble and install, which can easily lead to broken connections between small batteries, and the latter is difficult to sort out the internal connections. It is also difficult to determine which small battery is faulty during assembly or disassembly. Utility Model Content

[0028] The locking cover 5 is arranged on the rear cover 2, the locking groove 3 is arranged on the front cover 1, the limiting groove 301 is arranged on the locking groove 3, the limiting block 302 is arranged on the locking cover 5, and the locking groove 3 and the locking cover 5 are adapted to each other through the limiting block 302 and the limiting groove 301;

[0029] The spring bearing 9 is arranged on the locking cover 5 .

[0030] In another embodiment, the spring bearing 9 is disposed at the connection between the locking cover 5 and the rear cover 2 .

[0031] The locking cover 5 and the locking groove 3 are arranged in a rectangular body covering structure.

[0032] In this embodiment, an inlay 4 is further included, and the inlay 4 is arranged on the locking cover 5 .

[0033] In this embodiment, a clamping plate 7 is further provided in the cavity.

[0034] The number of the small batteries 6 is eight.

[0035] The eight small batteries 6 are arranged in two rows of four.

[0036] Specifically, for the convenience and safety of the lithium battery, first, eight small batteries 6 are arranged in the cavity formed by the combination of the front cover 1 and the rear cover 2, which are divided into four on the top and four on the bottom, and are arranged in parallel. The wiring 8 of the eight small batteries 6 will be uniformly connected to the card plate 7 to facilitate the output of power and uniform voltage. Then, the front cover 1 and the rear cover 2 are clamped together, the front cover 1 is provided with a locking cover 5, and the rear cover 2 is provided with a locking groove 3. The locking cover 5 and the locking groove 3 are clamped together. In order to make the locking cover 5 and the locking groove 3 firmly combined together, the limit block 302 on the locking cover 5 is adapted to the limit groove 301 on the locking groove 3 to achieve a more solid structure. In addition, the user can grab the inlay 4 on the locking cover 5 by hand, and the locking cover 5 is locked from the locking The locking groove 3 is separated to achieve the purpose of separating the front cover 1 and the rear cover 2. Similarly, in order to better fit the locking groove 3 and the locking cover 5, a spring bearing 9 is provided at the connection between the locking cover 5 and the rear cover 2. The spring bearing 9 itself has a certain elastic potential energy, so that the locking cover 5 itself has an elastic force to cover the locking groove 3.
