摘要： A method for manufacturing, a secondary battery separator including a porous resin film in which pores have three-dimensionally ordered structure and are in mutual communication via through-holes. The method includes: uniformly dispersing spherical microparticles having narrow particle size distribution in a dispersion medium to prepare a microparticles-dispersed slurry; drying slurry to obtain a spherical microparticles-dispersed film; heat-treating the film to form a microparticles-resin film in which the microparticles are regularly arrayed in three-dimensions in a resin matrix; and contacting the microparticles-resin film with an organic acid, water, an alkaline solution or an inorganic acid other than hydrofluoric acid to dissolve and remove the microparticles, or heating the microparticles-resin film to remove the microparticles, to form pores which are in mutual communication and regularly arrayed in the resin matrix. The medium has a resin precursor for the resin matrix and surfaces of the microparticles are inactive against the medium.

摘要： Provided is a separator which can make the electric field on the surface of a negative electrode for a metal secondary battery homogeneous to thereby prevent the formation of dendrites. A porous separator for metal secondary batteries, which has a polymer electrolyte layer formed on the surface layer of at least one main surface of a porous polyimide film. It is preferred that the polymer electrolyte layer is composed of both a polymer electrolyte material which is supported on at least one main surface of the porous polyimide film and a polymer electrolyte material which is supported in voids in a layered region that extends from the main surface.

摘要： (Problem to be Solved)The present application is to provide an all-solid-state lithium-sulfur battery that experiences little reduction in battery performance even after repeated charging/discharging cycling, does not generate toxic gas when damaged, and does not require addition of equipment or the like for management of moisture or oxygen concentration; and a production method for the all-solid-state lithium-sulfur battery.(Means for Solution)The present invention uses a positive electrode that contains sulfur and a conductive material, a negative electrode that contains lithium metal, and, as an electrolyte layer that is interposed between the positive electrode and the negative electrode, an oxide solid electrolyte to achieve a high-performance all-solid-state lithium-sulfur battery. According to the present invention, after a positive electrode slurry that contains sulfur is applied to a positive electrode side of an oxide solid electrolyte formation body and dried to form a positive electrode, the oxide solid electrolyte molded body is mounted upon a lithium foil that will become a negative electrode and adhered to the lithium foil. Said process allows for efficient assembly of a battery cell that is configured to have an oxide solid electrolyte interposed between a positive electrode and a negative electrode.
