Abstract

The invention discloses an explosion-proof lithium battery with good heat dissipation performance, which includes a casing, a cover is fixedly connected to the casing, an electric core is installed in the casing, and a positive terminal and a negative electrode are installed on the electric core connector, and both the positive terminal and the negative terminal run through the cover body, and a storage groove is opened on the housing, and spring buckles are symmetrically installed on the inner walls of both ends of the storage groove, and the two spring buckles are engaged together to form a A fixed block, the upper end of the fixed block is integrally formed with a heat sink, and the end of the heat sink away from the cover is fixedly connected with a baffle, and both the positive terminal and the negative terminal pass through the baffle, and on the side wall of the housing An explosion-proof device is installed, and an explosion-proof cavity is opened in the explosion-proof device. The invention has the advantages of stable structure, simple operation, scientific and reasonable design, short production cycle, low production cost, good heat dissipation performance, easy disassembly, good explosion-proof performance, and adjustable explosion-proof strength, so that the lithium battery is safer and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an explosion-proof lithium battery with good heat dissipation performance. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. Lithium, atomic number 3, atomic weight 6.941, is the lightest alkali metal element. [0003] After the lithium battery cell is overcharged to a voltage higher than 4.2V, it will start to have side effects. The higher the overcharge voltage, the higher the risk. After the lithium cell voltage is...
