HOMOGENIZATION METHOD FOR POSITIVE ELECTRODE MATERIAL

A homogenization method for a positive electrode material, comprising the following steps: S1, uniformly mixing a binder and a solvent, so as to obtain a first adhesive solution; S2, separately performing electrification treatment on a positive electrode active material and a conductive agent, so as to obtain a positive electrode active material having a same type of charge and a conductive agent having a same type of charge; S3, carrying out ultrasonic treatment and stirring treatment sequentially on the first adhesive solution, a conductive paste and the conductive agent having the same type of charge, so as to obtain a second adhesive solution; S4, uniformly mixing the positive electrode active material having the same type of charge, the second adhesive solution and the solvent, so as to obtain a positive electrode paste. The homogenization method for a positive electrode material improves the dispersion effect, reduces particle agglomeration, and can obtain uniform and stable positive electrode pastes. Additionally, the method involves simple steps, requires short time and achieves high efficiency.
