Low-temperature-resistant lithium ion battery

Abstract

The invention discloses a low-temperature-resistant lithium ion battery. The lithium battery comprises: a lithium battery body, wherein the lithium battery main body comprises a battery protection sleeve box, and the battery protection sleeve box is arranged to be of a rectangular structure; a junction box cover, wherein the junction box cover is arranged above the battery protection sleeve box, the battery protection sleeve is connected with the battery protection sleeve box through a clamping groove, a groove is formed in the bottom of the junction box cover, the size of the groove is the same as the plane size of the battery protection sleeve box; and electrode discharge grooves, wherein the five electrode discharge grooves are formed in the battery protection sleeve box, the electrodedischarge grooves are arranged in parallel, a positive electrode discharge module is arranged in each electrode discharge groove, an ion diaphragm is arranged on one side of each positive electrode discharge module, and a negative electrode discharge module is arranged on the other side of each ion diaphragm. When the lithium battery can be charged and discharged in a low-temperature state, the problems that the battery efficiency is reduced and the service life of the battery is shortened due to the influence of low temperature are solved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to low temperature resistant lithium ion batteries. 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 N. 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. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth gener...

AI Technical Summary

Problems solved by technology

[0005] Another object of the present invention is to provide a lithium-ion battery that is resistant to low temperature, so that when the lithium battery can be charged and discharged at a low temperature, it will not be affected by the low temperature, resulting in a decrease in battery efficiency and a shortened battery life.
