PROBLEM TO BE SOLVED: To provide a method for manufacturing a negative electrode for a solid battery, by which the degradation of sulfide-based solid electrolyte can be suppressed, a sufficient adhesive force between a collector and a negative electrode layer can be ensured, and the capacity degradation owing to a negative electrode can be suppressed.SOLUTION: A method for manufacturing a negative electrode for a solid battery comprises the steps of: preparing a slurry for the negative electrode by mixing a negative electrode active material, a sulfide-based solid electrolyte, a binder and a solvent; applying the prepared slurry for the negative electrode; and drying the applied slurry for the negative electrode. In the method, butyl butyrate is used as the solvent; and a copolymer including a vinylidene fluoride (VDF) monomer unit and a hexafluoropropylene (HFP) monomer unit, in which the mole ratio of the HFP monomer unit to the total mole number of the VDF monomer unit and the HFP monomer unit is 10-25% is used as the binder.SELECTED DRAWING: Figure 5 |
