Slurry stirring process for lithium-ion batteries and application

The invention provides a slurry stirring process for lithium-ion batteries and an application. The slurry stirring process comprises the following steps: (a) mixing an active material with a conductive agent to obtain mixed powder; and (b) mixing the mixed powder with a solvent and a binder under the condition of introducing a gas, and adding a defoaming agent for vacuum stirring dispersion to obtain slurry, wherein the flow of the gas is 1L/h to 50L/h. Compared with the prior art, according to the slurry stirring process for the lithium-ion battery provided by the invention, the active material is mixed with the conductive agent in a dry mixing manner, so that the mixing time of the slurry can be shortened; and the mixing uniformity is improved. Meanwhile, the gas is introduced in the solid-liquid mixing process as a mixed medium; and dispersion of the active material and the conductive agent in the solvent is facilitated, so that the stability of the slurry viscosity is greatly improved; the dispersity and
