Abstract:
Provided are a cobalt-free system, a positive electrode slurry, a slurry homogenization method therefor, and the use thereof. The cobalt-free system comprises a cobalt-free material, a binder, a conductive agent and a pH regulator. The cobalt-free system can reduce the rebound degree of the viscosity of a slurry after leaving to stand to the same degree as that of a ternary 811 single crystal, and can also improve the stability of the coating surface density of the cobalt-free material to the same level as that of a ternary material.
