US Patent 11949104 Slurry for forming electrode-active-material layer for cell

Provided is a slurry for forming an electrode-active-material layer, the slurry improving adhesion to a current collector while suppressing a decrease in cell capacity. The present invention provides a slurry for forming an electrode-active-material layer for a cell, the slurry including at least an active material and an aqueous binder, wherein the slurry has an aqueous binder content from 0.1 to 0.8 parts by weight based on 100 parts by weight of the active material, and a supernatant obtained by centrifuging the slurry has the aqueous binder content of 45% by weight or greater of a total amount of the aqueous binder contained in the slurry. The slurry of the present invention preferably further contains a fibrous material.
