An aspect of the present invention provides a manufacturing method for an electrolyte sheet, the manufacturing method including a step of molding a composition containing a polymer, Li[TFSI], oxide particles, and a dispersion medium into a sheet shape and volatilizing the dispersion medium at 100° C. or higher.

Electrolyte sheet and manufacturing method of secondary battery

A battery member includes: a current collector; an electrode mixture layer provided on the current collector; and an electrolyte layer provided on the electrode mixture layer, in which the electrode mixture layer contains an electrode active material, an organic solvent, a polymer, and an electrolyte salt, and the electrolyte layer contains a polymer, an oxide particle, and an electrolyte salt.

Battery member, method for manufacturing battery member, and secondary battery

A secondary battery includes: a positive electrode current collector; a negative electrode current collector; a positive electrode electrolytic solution part provided so as to be in contact with the positive electrode current collector, the positive electrode electrolytic solution part containing a positive electrode electrolytic solution; and a negative electrode electrolytic solution part provided so as to be in contact with the negative electrode current collector, the negative electrode electrolytic solution part containing a negative electrode electrolytic solution. The positive electrode electrolytic solution contains a positive electrode active material, an electrolyte salt, and a non-aqueous solvent containing a first solvent. The negative electrode electrolytic solution contains a negative electrode active material, an electrolyte salt, and a non-aqueous solvent containing a second solvent. The second solvent is a solvent having a reduction potential that is lower than an eigenvalue depending on the negative electrode active material.
