Abstract
An all-solid-state secondary battery having a higher level of safety than a conventional lithium-ion secondary battery using an electrolyte solution, specifically, a thin-film-type solid-state secondary battery, and a manufacturing method thereof are provided. As a solid electrolyte, a mixed material obtained by co-evaporation of SiO and an organic complex of lithium is used. That is, a solid electrolyte layer formed using a mixed material of an inorganic material and an organic material is used in a solid-state secondary battery. The ratio of oxygen to silicon in the solid electrolyte layer is higher than 1 and lower than 2.
