[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the highly active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. The existing lithium battery has poor heat dissipation when in use, which is easy to affect the service life of the lithium battery. In addition, the existing lithium battery has poor explosion-proof performance. It is easy for waste gas to accumulate when the lithium battery is short-circuited, causing expansion and causing accidents. Among them, a new cylindrical lithium battery with application number "CN202220358669.8" is used. The beneficial effects of the utility model are: the surface of the lithium battery is protected by a protective plate of insulating material to avoid leakage, and at the same time, a plurality of heat dissipation plates are used to support the shell and the protective plate, and the heat of the protective plate is introduced into the gap. At the same time, a plurality of first heat conduction blocks and second heat conduction blocks are used to cooperate to quickly introduce the heat of the heat dissipation plate and the gap to the outside, and a warning ring coated with reflective paint is used to facilitate users to observe the position of the lithium battery more intuitively. However, the battery still has certain shortcomings in practical applications: its structural design is relatively complex, and the production cost of a single battery is high. At the same time, the lithium battery of the above-mentioned type of structure cannot be mass-produced well, and the accumulation of the external structural design of the battery is easy to affect the direct heat dissipation of the battery, which will invisibly reduce the service life of the battery.
