摘要: The present disclosure addresses the problem of providing a novel oxide-based positive electrode active material having exceptional charge/discharge characteristics. The aforementioned problem is solved by an oxide-based positive electrode active material that is a glass ceramic configured to include: Li or Na; at least one transition metal (groups 3 to 12 in periods 4 and 5); and ions selected from the group consisting of sulfate ions, silicate ions, aluminate ions, germanate ions, borate ions, nitrate ions, carbonate ions, and halide ions.

摘要: An object is to provide a novel oxide-based ion conductor with improved ion conductivity over lithium oxide. The problem is solved by a noncrystalline ion conductor represented by the following formula:(Li2-xO1-xAx)1-yZy (I) (where A is one or more atoms selected from F, Cl, Br, and I, x satisfies 0.1≤x≤0.7, Z is a network-forming oxide, a network-modifying oxide (excluding Li2O), or an intermediate oxide, and y satisfies 0≤y≤0.25, except for those in which A is I and Z is SiO2 when 0.2≤y≤0.25).

摘要: The present invention addresses the problem of providing a countermeasure against deposition of an alkali metal in cases where the alkali metal is used as a negative electrode. The above-described problem is solved by a negative electrode composite body that contains: a negative electrode active material which contains, as main components, Li and an element M that is solid soluble in Li; and a substance X which has a higher redox potential than the negative electrode active material, or a substance X which does not have electrode activity.
