Lithium battery electrolyte injection method

Abstract

The invention discloses a lithium battery electrolyte injection method. The method comprises the following steps: S1, battery preparation: preparing a battery on which electrolyte injection is to be carried out, weighing the battery on which the electrolyte injection is to be carried out, and baking the weighed battery in an oven for later use; S2, humidity detection: carrying out the humidity detection on the battery prepared in S1, converting data obtained after the detection into images, and displaying the images on a computer; S3, short circuit testing: when the humidity of the battery detected in S2 reaches a prescribed value, carrying out short circuit testing processing on the battery subjected to the humidity detection; and S4, preparation before the electrolyte injection: after the battery short circuit testing in S3 is completed, preparing an electrolyte injection machine, and carrying out vacuumizing processing on the electrolyte injection machine. The method provided by theinvention has the advantages that the original technique is simplified, so that an electrolyte injection process is greatly shortened, the battery is in contact with moisture in air for a shorter period, and high simplicity in operation is achieved; and masses of the battery after the electrolyte injection and before the electrolyte injection are carefully weighed, so that the electrolyte injection precision is improved.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to a lithium battery electrolyte injection method. Background technique [0002] With the rapid development of science and technology and economy, the functions of electronic products in the market are becoming more and more powerful, and the shape and size requirements are getting smaller and lighter. Lithium-ion batteries have the advantages of small size, high energy, high working voltage, no environmental pollution, long cycle life, and wide operating temperature range. They are widely used in mobile phones, notebook computers, digital cameras and other electronic products, and even in automobiles. superior. Therefore, the requirements for small size and light weight of electronic products are reflected in the lithium batteries that provide power, and the requirements for lithium-ion batteries are getting higher and higher, especially lithium-ion batteries that need ...

Problems solved by technology

Therefore, it is necessary to absorb as much electrolyte as possible in a limited space, provide the electrolyte required by the battery, and improve the cycle life of the battery. The operation of the current lithium battery electrolyte is more complicated when injecting the liquid, and the result of the injection is wrong. larger
