Embodiment Construction

[0024] The present invention is further illustrated below by way of examples.

[0025] Now take the 1FP11190316-57 model lithium-ion battery as an example to further illustrate the present invention, and the specific steps are as follows:

[0026] a, inject conventional amount m into the embodiment lithium-ion battery of assembling molding 1 electrolyte, the example capacity of this case is 57 ampere hours, and the conventional amount of injected electrolyte is m 1 According to the addition of 5g per ampere hour, it is 285g;

[0027] b. After acid injection and before packaging, the free electrolyte of lithium-ion batteries is collected, and the collection volume is m 2 , the amount collected in this example m 2 5g;

[0028] c. Calculate the corrected injection volume m 3 = m 1 -m 2 ;

[0029] =285-5

[0030] =280(g)

[0031] D, measure the liquid absorption m of built-in positive electrode sheet, negative electrode sheet and diaphragm of embodiment lithium ion batte...

Abstract

The invention discloses a method for calculating the liquid injecting amount of a lithium ion battery. The method is carried out according to the following steps: a, injecting a conventional amount m1of electrolyte into an assembled lithium ion battery; b, after acid injection, collecting free electrolyte of the lithium ion battery before packaging, wherein the collection amount is m2; c, calculating the corrected liquid injection amount m3=m1-m2; d, measuring the liquid absorption amount m4 of each of a positive plate, a negative plate and a membrane arranged in the lithium ion battery; e, obtaining the optimal liquid injection amount. The calculation method is simple, makes calculation results accurate and is beneficial to defining of the optimal liquid injection amount, so that the waste of the electrolyte is decreased, the environmental pollution is also reduced, and the manufacturing cost is saved.

Description

technical field [0001] The invention belongs to the technical field of electrochemical battery manufacturing. Specifically, the invention relates to a method for calculating the liquid injection volume of a battery, in particular to a calculation method for the liquid injection volume of a lithium ion battery. Background technique [0002] With the advancement of science and technology, and the improvement of the public's material and cultural living standards, people's demand for green energy lithium-ion batteries that are small in size, light in weight, high in energy, safe, reliable, and pollution-free, and can be recharged and used is increasing. Big. Of course, people's requirements for battery performance are getting higher and higher, so it is very important to accurately inject electrolyte into high-capacity batteries with high specific energy. [0003] Electrolyte, as the medium for lithium ion transmission in lithium-ion batteries, is a bridge connecting the posit...
