Abstract:
(EN) In order for Li ions in a stock solution to be recovered at a high recovery speed in a recovery liquid, this selectively permeable membrane (10) is configured from a selectively permeable membrane main body (10A) configured from: a lithium superionic conductor (an ion conductor) having an especially high ionic conductivity; and a Li adsorption layer (10B) which is formed as a thin layer on the selectively permeable membrane main body (10A) facing the stock solution (100) (on first electrodes (11)). A lithium lanthanum titanate specifically can be used as the material configuring the selectively permeable membrane main body (10A). By chemically treating said selectively permeable membrane main body (10A), the Li adsorption layer (10B) is formed as a thin layer on the surface of the selectively permeable membrane main body (10A).
(FR) Afin que des ions Li dans une solution mère soient récupérés à une vitesse de récupération élevée dans un liquide de récupération, la présente invention concerne une membrane sélectivement perméable (10) qui est constituée d’un corps principal de membrane sélectivement perméable (10A) constitué de : un conducteur superionique de lithium (un conducteur d’ions) ayant une conductivité ionique particulièrement élevée ; et une couche d’absorption de Li (10B) qui est formée sous la forme d’une couche mince sur le corps principal de membrane sélectivement perméable (10A) faisant face à la solution mère (100) (sur des premières électrodes (11)). Un titanate de lithium-lanthane peut spécifiquement être utilisé en tant que matériau constituant le corps principal de membrane sélectivement perméable (10A). En traitant chimiquement ledit corps principal de membrane sélectivement perméable (10A), la couche d’adsorption de Li (10B) est formée sous la forme d’une couche mince sur la surface du corps principal de membrane sélectivement perméable (10A).
(JA) 原液中のLiイオンを高い回収速度で回収液中に回収する。 選択透過膜(10)は、特に高いイオン伝導率をもつ超リチウムイオン伝導体(イオン伝導体)で構成された選択透過膜本体(10A)と、その原液(100)側(第1電極(11))に薄層として形成されたLi吸着層(10B)で構成される。選択透過膜本体(10A)を構成する材料としては、具体的にはチタン酸リチウムランタンを用いることができる。Li吸着層(10B)は、この選択透過膜本体(10A)に対して化学処理を行うことによって選択透過膜本体(10A)の表面に薄層として形成される。
