Preparation process of lithium battery slurry

Abstract

The invention discloses a preparation process of lithium battery slurry. The preparation process comprises the steps: (1) adding gelatin powder into a first stirring container, adding a first part of solvent, carrying out vacuum stirring, and uniformly mixing to obtain liquid cement, wherein the first part of solvent is 10 to 15 percent of the weight of the entire solvent; (2) adding conductive agent powder into a second stirring container, adding a second part of solvent, carrying out vacuum stirring, and uniformly mixing to obtain a conductive agent solution, wherein the second part of solvent is 5 to 15 percent of the weight of the entire solvent; (3) adding active substance powder into a third stirring container, adding a third part of solvent, carrying out vacuum stirring, and uniformly mixing to obtain an active substance solution, wherein the third part of solvent is 10 to 35 percent of the weight of the entire solvent; and (4) adding the conductive agent solution and the active substance solution into the liquid cement, adding the remaining solvent, carrying out vacuum stirring, and uniformly mixing to obtain lithium battery slurry. According to the preparation process of the lithium battery slurry, the preparation time of the slurry is short, and the prepared slurry is more uniform and good in stability.

Description

The pulping process is the most important link in the entire production process of lithium-ion batteries, which has an impact on product quality of more than 30%. However, most of the current processes still use ...

AI Technical Summary

Problems solved by technology

However, most of the current processes still use the traditional slurry preparation process, and the high-speed dispersion process is used to disperse the slurry. The slurry prepared by this process is prone to agglomeration, poor uniformity, poor stability, and long processing time.

The performance consistency of lithium-ion batteries prepared by using this slurry is poor, which affects the assembly and use of lithium-ion batteries
