Abstract

The invention discloses an explosion-proof lithium battery. A structure comprises a lithium battery, a top cover, a shell, protective covers and a binding post. The top cover is embedded and fixedly connected with the lithium battery; the shell and the lithium battery are an integrated structure; the binding post is embedded and fixedly connected with the lithium battery; the two protective coversare arranged at external positions of the binding post; the situation that water drops are attached to the binding post can be effectively isolated through the protective covers; a problem that condensed water drops are easily attached to the binding post due to a temperature difference when the lithium battery is charged so that a short circuit is caused is avoided; through an insulating plate,electricity on a conductive plate can be effectively isolated so that potential safety hazards caused by contact between water absorbed by a water absorption sheet and electricity are avoided; and after the lithium battery is charged, a water collecting block can be reset through a reset mechanism, and a contact area between the water absorption sheet and air can be increased so that an evaporation speed of water in the water absorption sheet is improved, and a water absorbing effect of the water absorption sheet is prevented from being reduced when the water absorption sheet is used again.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to an explosion-proof lithium battery. Background technique [0002] Lithium batteries for electric vehicles are mainly used to provide power for electric vehicles. They can store power in the lithium battery, and then release the power through the positive and negative terminals to drive electric vehicles. Due to the high safety performance requirements of electric vehicles, so Most electric vehicles use explosion-proof lithium batteries for power supply. Based on the above description, the inventors found that the existing explosion-proof lithium batteries mainly have the following deficiencies, for example: [0003] Due to the cold weather in the south and the humid air, the temperature will rise when the lithium battery of the electric vehicle is charged, and it is easy to generate a temperature difference with the outside world, resulting in condensation of water droplets on th...
