The invention discloses a mixing process for improving the low-temperature performance of a
lithium battery. The mixing process comprises the following steps of: dispersing large
powder in a solution,uniformly distributing the large
powder, and dispersing secondary aggregates formed by an
electrode active material in production
slurry of the
lithium battery by using a dispersing
assembly of dispersing equipment. The dispersing equipment comprises a bottom plate, a dispersing shell, a dispersing cover, the dispersing
assembly, a rotating
assembly, supporting legs, a first connecting rod, a second connecting rod, a discharging
pipe and an
electromagnetic valve, and the dispersing assembly comprises a dispersing motor, a fixing base, a stabilizing shell, a buffer cavity, a spring, a stabilizing sleeve, a rotating shaft, a dispersing
grinding head, a dispersing
grinding body, an
impeller grinding head and an inner ring. The rotating assembly drives
slurry on the edge in the dispersing shell to move reversely, the rotating assembly comprises a protective shell, a gear ring, a through hole, a gear, a fixing frame and a rotating motor, then the dispersing assembly achieves uniform dispersing, and the total comprehensive performance of a
lithium battery is greatly improved.
