▎ 摘　　要

NOVELTY - An agglomerant composition comprises polyacrylonitrile and polyvinylidene fluoride in a mass ratio of (1-8):(2-9). USE - Agglomerant composition is used for treating sodium ion secondary battery anode used in energy storage field, mixed power field and replacing lead-acid battery field. ADVANTAGE - The sodium ion secondary battery anode contains alkali-resistant binder and dispersant, at least can effectively prevent the slurry preparation process and slurry jelly in the coating process, the presence of scratch problem in coating process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Sodium ion secondary battery anode; and A sodium ion secondary battery.
