1, ion exchange: this step is to form a manganese salt with a certain structure through the implementation of multiple chlorination and substitution reactions mediated by catalysts. This not only improves the structure of the material, but also helps to distribute the original manganese in the cathode more effectively and evenly.
2. Solution mixing: This step includes fully mixing the ion-exchanged cathode material with electrolyte (high-concentration chlorinated carp and manganese chloride) to make the cathode material fully permeate the electrolyte, thus effectively improving the structure of all participants in the discharge reaction.
3. Heat treatment: Its purpose is to transform the original solution mixture into a molten state, thus further promoting the absorption of electrolyte and the activation of cathode materials under the conditions involved. In order to prevent the abnormal occurrence, small current and constant voltage are needed in the heat treatment of cathode materials to reduce unnecessary damage. Before full activation, the mixture must be heat-treated again to absorb electrolyte to the maximum extent and improve the structure of cathode materials.
