▎ 摘　　要

NOVELTY - Preparing electrode film involves obtaining an agglomerant emulsion, spray-drying the agglomerant emulsion to prepare agglomerant micropowder, mixing the agglomerant micropowder and the electrode matrix material in-situ to prepare a premix and rolling the premix into a film. USE - The method for preparing electrode film is useful for energy storage device e.g. capacitor, battery lithium-ion capacitor and fuel cell for supplying power to electronic device. ADVANTAGE - The method provides electrode film with good adhesive film forming effect, good electric performance and good mechanical property, which effectively reduces the dosage of the agglomerant. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: an electrode sheet; and a preparation method of the electrode sheet.
