Abstract:
A positive electrode material includes a positive electrode active material, a cover layer that covers at least part of a surface of the positive electrode active material and that contains a first solid electrolyte material, and a second solid electrolyte material that is a material different from the first solid electrolyte material. The first solid electrolyte material contains Li, M, and X and does not contain sulfur. M represents at least one element selected from the group consisting of metal elements other than Li and semi-metal elements, and X represents halogen elements including Cl.
Abstract:
A solid electrolyte consists essentially of Li, M, and X. M includes at least one element selected from the group consisting of Gd, Tb, and Sm. X is at least one element selected from the group consisting of Cl, Br, and I.
Abstract:
A solid electrolyte contains a composite metal halide. The composite metal halide contains magnesium, an alkaline-earth metal having a larger ionic radius than magnesium, gallium, and a halogen. In the composite metal halide, the molar ratio of the alkaline-earth metal to the total of magnesium and the alkaline-earth metal is less than 0.2.
Abstract:
A solid electrolyte includes a matrix including, as a salt, containing a metal halide containing an alkaline-earth metal and a group 13 metal, and at least one filler located in the matrix.
Abstract:
A solid electrolyte includes: a matrix containing, as a solid salt, at least one selected from the group consisting of (i) a metal halide containing an alkaline-earth metal and (ii) a metal compound containing the alkaline-earth metal and fluorine; and one or more fillers embedded in the matrix.
Abstract:
An electrical storage device includes a stack structure including a conductive first electrode layer, a conductive second electrode layer, a charging layer disposed between the first electrode layer and the second electrode layer, the charging layer including a mixture containing an insulating material and at least one metal oxide selected from the group consisting of niobium oxide, tantalum oxide and molybdenum oxide, and an electron barrier layer disposed between the charging layer and the second electrode layer.
