Sheet for all solid state secondary battery and manufacturing method of all solid state secondary battery, sheet for all solid state secondary battery and all solid state rechargeable battery

摘要

A method for producing a sheet for an all-solid secondary battery containing a sulfide-based inorganic solid electrolyte having a volume average particle diameter of 1.0 μm or less and a particulate organic component, wherein the particle organic component and the volume average particle diameter are 1.0 μm or less. A mixture containing the sulfide-based inorganic solid electrolyte of the above and having a content of the particulate organic component of 15% by mass or less in the total content of the sulfide-based inorganic solid electrolyte and the particulate organic component. It includes pressurizing at a temperature higher than the glass transition temperature of the particulate organic component by 20 ° C. or more and lower than the decomposition temperature of the particulate organic component at a pressure higher than 1/10 of the elastic coefficient of the particulate organic component. , A method for manufacturing a sheet for an all-solid secondary battery, a method for manufacturing a sheet for an all-solid secondary battery, and a sheet for an all-solid secondary battery and an all-solid secondary battery.
