Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A solid-state secondary battery comprising: a positive electrode; a negative electrode; and a solid electrolyte layer containing silicon, oxygen, lithium, and carbon between the positive electrode and the negative electrode. 2 . The solid-state secondary battery according to claim 1 , wherein the solid electrolyte layer further contains nitrogen. 3 . The solid-state secondary battery according to claim 1 , wherein a negative electrode active material layer containing silicon is included between the negative electrode and the solid electrolyte layer. 4 . The solid-state secondary battery according to claim 1 , wherein a positive electrode active material layer is included between the positive electrode and the solid electrolyte layer. 5 . The solid-state secondary battery according to claim 1 , wherein the ratio of oxygen to silicon in the solid electrolyte layer is higher than 1 and lower than 2.
