Lithium battery shell capable of automatically and intelligently supplementing electrolyte

Abstract

The invention relates to the technical field of lithium batteries, and discloses a lithium battery shell capable of automatically and intelligently supplementing electrolyte, the lithium battery shell comprises an aluminum-plastic shell and a connecting pipe, a negative electrode material is arranged in the aluminum-plastic shell, a diaphragm is arranged in the negative electrode material, a positive electrode material is arranged in the diaphragm, a positive electrode rod is attached to the positive electrode material, and a negative electrode rod is attached to the positive electrode rod. A positive pole lug is mounted at the top end of the positive pole rod, a negative pole lug is arranged at the top end of the aluminum-plastic shell, an insulating sheet is arranged between the aluminum-plastic shell and the negative pole lug, electrolyte is arranged in the connecting pipe, a fixed pipe is fixedly connected to the top surface of the connecting pipe, and a through hole is formed in the top of the connecting pipe. According to the lithium battery capable of automatically and intelligently supplementing the electrolyte, the shell and the check block are separated from the circulating groove, and the electrolyte in the supplementing box flows into the connecting pipe through the through hole at the moment, so that the effect of automatically supplementing the electrolyte is achieved, independent operation of personnel is not needed, risks can be effectively reduced, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery casing for automatically and intelligently replenishing electrolyte. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, so this battery is also called a lithium metal battery. Unlike other batteries, Li-ion batteries have the characteristics of high charge density, long life and high unit cost. According to different structural design and electrode materials, lithium batteries can generate voltages from 1.5 V (equivalent to zinc-carbon or alkaline batteries) to 3.7 V. Early lithium batteries were primary batteries, but due to the very active chemical properties of metal lithium, it Processing, storage, and use have very high environmental requirements. Therefore, lithium batteries have not been widely used after their inv...
