▎ 摘  要

NOVELTY - Performing dispersion of slurry for aluminum battery involves providing a first dispersion liquid with active powder and a second dispersion liquid with conductive powder separately, where the second dispersion liquid is different from the first dispersion liquid, and mixing and dispersing the first dispersion liquid and the second dispersion liquid by one or more of three-roll rolling, ball milling, centrifugal stirring, and planetary stirring to make a slurry. USE - Method for performing dispersion of slurry for aluminum battery. ADVANTAGE - The design and combination of different dispersion processes effectively improve the uneven dispersion of the slurry, slow down the problem of sediment separation of the solid composition, increase the conductivity of the electrode (positive or negative), and maintain the high lifetime of the battery even at high charging and discharging rates. A slurry with a uniform dispersion is made by the dispersion method of slurry for aluminum battery of the disclosure, improving the performance of the aluminum battery.
