Abstract

Disclosed are a positive electrode and a preparation method thereof and a battery. The positive electrode includes a current collector, an active material layer, and a conductive layer disposed between the current collector and the active material layer. The conductive layer includes an MXene material. Adding the MXene material in the conductive layer may elevate the conductive performance and stability of the battery, and may also strengthen the adhesion between the current collector and the active material layer, enhance the peel force of the positive electrode, and improve the long-term cycle stability of the battery. In addition, since the addition of the MXene material enhances the adhesion between the current collector and the active material layer, under the condition that the peel strength of the electrode sheet is ensured, the content of binder in the active material layer may be reduced.
