Abstract

The invention relates to an explosion-proof flame-retardant lithium-ion battery safety box comprising a lithium-ion battery pack and a sealed box; the sealed box comprises a box body and a top cover; the top cover and the box body are connected in a seal way; the lithium-ion battery pack is arranged in the box body; a radiating fin, a positive pole conductive terminal and a negative pole conductive terminal are arranged on the top cover; and a gas valve which is used for vacuumizing and is filled with inert gas is arranged on the top cover. The invention provides the explosion-proof flame-retardant lithium-ion battery safety box which can effectively prevent the explosion of single batteries or the battery pack, and greatly improve the safety performance.

Description

technical field [0001] The invention relates to a lithium ion battery box. Background technique [0002] Due to the high energy density of lithium-ion batteries, the flammability of organic electrolyte solutions and the active characteristics of lithium, lithium-ion batteries have inherent defects in safety compared with traditional secondary batteries. Lithium-ion power batteries used as power generally require high power output due to their large capacity, so the batteries heat up severely during work, and the potential safety hazards increase significantly, especially when they are abused by thermal shock, overcharge, overdischarge, and short circuit. In this state, chemical and electrochemical reactions will occur between the active materials and electrolyte components inside the battery, generating a large amount of heat and gas, which will cause the battery to catch fire and explode when accumulated to a certain extent. Therefore, lithium-ion power batteries are usuall...
