SLURRY FOR SULFIDE-BASED SOLID BATTERY NEGATIVE ELECTRODE, SULFIDE-BASED SOLID BATTERY NEGATIVE ELECTRODE AND MANUFACTURING METHOD THEREOF, AND SULFIDE-BASED SOLID BATTERY AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a slurry which enables the formation of a sulfide-based solid battery negative electrode achieving good performance balance, and to provide a sulfide-based solid battery negative electrode and a manufacturing method thereof, and a sulfide-based solid battery and a manufacturing method thereof.SOLUTION: A slurry for a sulfide-based solid battery negative electrode comprises at least, a fluorine-based copolymer including a vinylidene fluoride monomer unit, a negative electrode active material, and a solvent or a dispersant. The content of the fluorine-based copolymer is 1.4-2.2 vol.% given the dry volume of the slurry is 100 vol.%.
