The invention relates to the technical field of battery electrode preparation, and particularly provides a preparation method and preparation equipment of an electrode film. The invention aims to solve the problems that the overall performance of an energy storage device is influenced due to the introduction of a non-functional material in a traditional electrode film preparation process, and the total cost of the energy storage device is increased due to the need of a large amount of energy consumption, complex manufacturing process and high equipment cost in a solvent removal process. In order to achieve the purpose, the preparation method of the electrode film comprises the steps that an electrode powder mixture is put into a feeding device, the electrode powder mixture is fed into a first rolling unit through the feeding device to be rolled, a primary electrode film is obtained, the primary electrode film is fed into a second rolling unit to be further rolled, and the electrode film is obtained.
