IONIC CONDUCTOR SLURRY, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

Disclosed is an ionic conductor slurry, a preparation method therefor and an application thereof. The ionic conductor slurry comprised parts by mass: 0.05 wt %-99.98 wt % of an ionic conductor powder material, 0 wt %-2 wt % of an anti-settling agent, 0 wt %-10 wt % of a binder, 0 wt %-2 wt % of a dispersant, 0 wt %-2 wt % of an auxiliary agent, and 20 wt %-99.95 wt % of a solvent, wherein the ionic conductor powder material comprises one among the following: a garnet-type solid electrolyte material, a NASICON-type solid electrolyte material, a LISICON-type solid electrolyte material, a perovskite-type solid electrolyte material, and derivatives thereof; The particle size of the ionic conductor powder is between 1 nm to 100 μm; and the ionic conductor slurry is used for separator coating material, positive electrode material coating materials, negative electrode material cladding materials, positive electrode material additive, a negative electrode material additive, polymer solid electrolyte additives, or solid-liquid mixed solid electrolyte.
