Abstract:
The present invention provides a binder and a slurry, which are suitable for use in the production of an electrode for a sulfide-based solid-state battery. A binder which is used in a slurry for solid-state batteries, said slurry containing sulfide-based solid electrolyte particles, and which is characterized by being a polymer that has at least one copolymerization unit (A) selected from the group consisting of monomer units having a structure represented by general formula (1) and monomer units having a structure represented by general formula (2). In the formulae, each of Rf1 and Rf2 represents a linear or branched fluorinated alkyl group or fluorinated alkoxy group having 1 to 12 carbon atoms, and in cases where the fluorinated alkyl group or fluorinated alkoxy group has 2 or more carbon atoms, an oxygen atom may be contained between two carbon atoms.
