In the production of lithium-ion battery electrolytes, there are many things that are not strictly controlled, one is dust, two is metal particles, three is moisture. The electrolytic solution of lithium-ion batteries comprises: the requirements, experimental methods, inspection rules, signs, packaging, transportation and storage of lithium ion batteries. Among them, technical indicators include chromaticity, density (25 ¡ã C), free acid, conductivity (25 ¡ã C), moisture, metal impurity content, sulfate ions, and chloride content.

The lithium ion battery electrolyte is a carrier of the ionically transmitted battery. It is generally consisting of a lithium salt and an organic solvent. Lithium-ion battery electrolyte water content factory standard is less than or equal to 20 ppm (also required to be less than 50 ppm), normal value of about 10 ppm, electrolyte moisture ultra-high should cause ultra-high hydrofluidic acid content and negative powder (PVDF) The adhesive) and copper foil peeling not only affects the performance of the lithium ion battery but also affects the quality of the lithium ion battery, so the temperature of the electrolyte moisture liquid in the lithium ion battery is not dilute.
