    摘要： According to one approach, a secondary battery (100) including a positive electrode (5), a negative electrode (3), an insulating layer, and a nonaqueous electrolyte is provided. The positive electrode (5) includes a positive electrode active material-containing layer (b) which contains a lithium nickel cobalt manganese composite oxide. The negative electrode (3) includes a negative electrode active material-containing layer (5b) that has a first surface (13) . The insulating layer includes a solid electrolyte layer (4b) that has a second surface (14) that is at least partly opposed to or partly in contact with the first surface (13) . The solid electrolyte layer contains a Li ion conductive oxide. At least part of the second surface (14) or the first and second surfaces (13, 14) includes a Mn-containing substance. An abundance ratio of Mn on the second surface (14) is higher than an abundance ratio of Mn on the first surface (13).

    摘要： According to one approach, a secondary battery (100) is provided. The secondary battery (100) includes a negative electrode (3), a positive electrode (5), a first aqueous electrolyte (8), a second aqueous electrolyte (9), and a partition (4) having a first surface and a second surface opposite to the first surface. The partition (4) is positioned between the negative electrode (3) and the positive electrode (5). The first aqueous electrolyte (8) is in contact with the first surface of the partition (4) and the negative electrode (3). The second aqueous electrolyte (9) is in contact with the second surface of the partition (4) and the positive electrode (5). The partition (4) contains a solid electrolyte having alkali metal ion conductivity. The first aqueous electrolyte (8) includes an organic compound.

    摘要： According to an approach, a secondary battery (100) is provided. The secondary battery (100) includes a positive electrode (52), a negative electrode (51), separator (53), and an aqueous electrolyte (AE). The separator (53) is located at least between the positive electrode (52) and the negative electrode (51). The separator (53) includes a composite film. The composite film includes a mixture of a polymeric material and ion conductive solid electrolyte particles having alkali metal ions conductivity. The polymeric material includes a polymer comprising a monomer unit. The monomer unit is a hydrocarbon with a functional group including at least one element selected from the group consisting of oxygen (O), sulfur (S), nitrogen (N), and fluorine (F). A ratio of the polymer in the polymeric material is not less than 70 mol%.
