Abstract

The invention discloses a lithium battery protection device. The lithium battery protection device comprises a box body, wherein the box body comprises a shell, a protection layer is arranged at an inner side of the shell, a printed circuit board (PCB) is arranged at the bottom of an inner cavity of the box body, an induction plate is arranged at the top of the PCB, a pressure sensor and a temperature sensor are arranged in the induction plate, an electrode interface is formed in the induction plate, red copper nets are arranged in the inner cavity of the box body, a lower insertion block is arranged on the box body, and an output interface is formed in a side wall of the box body. By employing the protection layer made of a flannelette material, the static generated by friction of the lithium battery during placement and usage is effectively reduced; by arranging the red copper nets arranged at intervals, an electromagnetic radiation signal is effectively shielded, and normal workingof the lithium battery is prevented from being intervened by electromagnetism; and by arranging an air valve and a sealing ring, a sealing structure is arranged, nitrogen is filled after air in the inner cavity of the box body is pumped by the air valve, so that leaked lithium atoms cannot react with oxygen to generate explosion during breakage of the lithium battery, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery protection device. 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. In 1912, the lithium metal battery was first proposed and studied by Gilbert.Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. 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. With the popularization of electronic equipment, lithium batteries have been widely used in all aspects of life, and the gradual promotion of new energy vehicles has furth...
