Abstract: A method for preparing a positive electrode plate, a positive electrode plate, and a battery including same. The method for preparing a positive electrode plate includes: providing a current collector, the current collector including a coating region and a non-coating region; coating a positive-electrode active material on the coating region of the current collector; cutting the non-coating region at intervals along a length direction of the non-coating region to form a tab between every two adjacent cutting positions, an edge of a region of the positive-electrode active material corresponding to the cutting position being cut off at each cutting; and coating an electrically insulating adhesive on an edge of the positive-electrode active material between every two adjacent cutting positions.
