Embodiment 1

[0013] A method for solving the problem of internal gas and electrolyte residue during the formation of hard-shell lithium batteries comprises the following steps:

[0014] (1) Put the hard-shell lithium battery on the battery positioning mechanism, connect the nitrogen injection port and vacuum head of the battery positioning mechanism with the liquid injection port of the hard-shell lithium battery, and adjust the negative pressure P1 and positive pressure on the battery positioning mechanism. Pressure P2, time T1 of the vacuum controller, time T2 of the nitrogen controller;

[0015] (2) Turn on the main power switch, vacuum controller switch and nitrogen controller switch of the battery positioning mechanism;

[0016] (3) Turn on the start switch of the battery positioning mechanism, the battery positioning mechanism starts to evacuate the battery T1, when the pressure in the battery is P1, it will automatically maintain the pressure for T3, and then start filling nitrogen ...

Abstract

The invention belongs to the technical field of a lithium battery, and particularly relates to a method for solving the residue of internal gas and electrolyte in the formation of a hard-shell lithium battery, which mainly solves the problems that the surplus electrolyte inside the battery cannot be discharged when the hard-shell lithium ion battery discharges the gas and the property and the service life of the battery are influenced. The technical scheme is as follows: the method for solving the residue of the internal gas and electrolyte in the formation of the hard-shell lithium battery comprises the following steps of (1) placing the hard-shell lithium battery on a battery positioning mechanism, adjusting the negative pressure P1 and the positive pressure P2 on the battery positioning mechanism, the time T1 of a vacuum controller and the time T2 of a nitrogen controller; (2) turning on a switch of the battery positioning mechanism; (3) turning on a starting switch of the battery positioning mechanism; and (4) ascending a battery pressure head, taking out the battery, and installing a battery explosion-proof valve by an operator when the pressure retention time T4 is reached. The method has the advantages of stable property and convenience in application.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a method for solving the problem of internal gas and electrolyte residue during formation of a hard-shell lithium battery. Background technique [0002] At present, large-capacity hard-shell lithium-ion batteries are mainly used in power and energy storage systems. The reason is that lithium-ion batteries have the advantages of high energy density, long life and low pollution. However, in the actual production process, it is found that the hard-shell lithium-ion battery produces more gas inside the battery after formation, and there is excess electrolyte residue, which seriously affects the performance of the battery. Now, for the method of dealing with the gas generated during the formation of hard-shell batteries, use a syringe to insert on the explosion-proof valve of the battery during the formation, and discharge the gas generated during the formation, ...
