▎ 摘  要

NOVELTY - Anode plate comprising an anode current collector and an anode slurry coated on the surface of the anode current collector. The anode slurry includes anode active material, conductive agent, and binder in a mass ratio of (90-95):(3-5):(3-5). USE - Pole anode of pole piece used in preparation method of button-type half battery used in battery preparation technology field. ADVANTAGE - The method provides an anode film in the field of battery manufacturing technology. The anode film includes an anode current collector and a anode slurry coated on the surface of the anode current collector. The anode slurry comprises an active material, conductive agent, and binder in a mass ratio of (90-95):(3-5):(3-5). The anode also includes a button-type half-cell comprising the anode film. By using a coated aluminum foil and adjusting the proportions of the slurry materials, the internal resistance of the battery is reduced, thus improving the initial charge-discharge efficiency and capacity of the battery. Additionally, the uniformity of the button cell is improved due to the thickness of the coated aluminum foil being 1 μm. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a preparation method of the anode sheet; (2) a button-type half battery; and (3) a preparation method of button-type half battery.
