Abstract

The invention discloses a lithium battery with good heat radiation properties and explosion prevention. The lithium battery comprises a shell, wherein a cover body is fixedly connected with the shell;a battery cell is mounted inside the shell; an anode connector and a cathode connector are mounted on the battery cell; both the anode connector and the cathode connector penetrate through the coverbody; a containing groove is formed in the shell; spring buckles are symmetrically mounted on inner walls at two ends of the containing groove; the two spring buckles are clamped with a fixing block;a heat radiation rack is integrally formed at the upper end of the fixing block; a baffle piece is fixedly connected with one end, far away from the cover body, of the heat radiation rack; both the anode connector and the cathode connector penetrate through the baffle pieces; an anti-explosion device is mounted on a side wall of the shell; an anti-explosion cavity is formed inside the anti-explosion device. The lithium battery is stable in structure, simple to operate, scientific and reasonable in design, short in production cycle, low in production cost, good in heat radiation property, convenient to dismount, and good in anti-explosion property; because the anti-explosion grade of the lithium battery can be adjusted, the lithium battery is relatively safe and is 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...
