description Provided are an ion conductor, a composite, a sheet, an electrode, a separator, and a power storage device that enable control of lithium-ion conductivity. An ion conductor (10) includes a solid electrolyte (19) that has a garnet-type crystal structure containing lithium, lanthanum, zirconium, and oxygen, and lithium carbonate (19a) is present in a part of a surface of the solid electrolyte. A composite (19d) includes the ion conductor and an ion liquid in which a lithium salt has been dissolved; the ion liquid contains fluorine-based anion; and the relative concentration ratio of fluoride to carbonate ions in a film (19c) that covers the surface of the solid electrolyte is at least 0.1. This power storage device (11) includes the ion conductor. Sont prévus un conducteur d'ions, un composite, une feuille, une électrode, un séparateur et un dispositif de stockage d'énergie qui permettent la commande de la conductivité lithium-ion. Un conducteur d'ions (10) comprend un électrolyte solide (19) qui a une structure cristalline de type grenat contenant du lithium, du lanthane, du zirconium et de l'oxygène, et du carbonate de lithium (19a) est présent dans une partie d'une surface de l'électrolyte solide. Un composite (19d) comprend le conducteur d'ions et un liquide ionique dans lequel un sel de lithium a été dissous ; le liquide ionique contient un anion à base de fluor ; et le rapport de concentration relative de fluorure à des ions carbonate dans un film (19c) qui recouvre la surface de l'électrolyte solide est d'au moins 0,1. Ce dispositif de stockage d'énergie (11) comprend le conducteur d'ions. リチウムイオン伝導性を制御できるイオン伝導体、複合体、シート、電極、セパレータ及び蓄電デバイスを提供する。イオン伝導体(10)は、Li,La,Zr及びOを含むガーネット型の結晶構造を有する固体電解質(19)を含み、固体電解質の表面に炭酸リチウム(19a)が部分的に存在する。複合体(19d)は、イオン伝導体と、リチウム塩が溶解したイオン液体と、を含み、イオン液体はフッ素系アニオンを含み、固体電解質の表面を覆う膜(19c)は、炭酸イオンに対するフッ化物の相対濃度比が0.1以上である。蓄電デバイス(11)はイオン伝導体を含む。
