ION CONDUCTOR, ION CONDUCTIVE SINTERED COMPACT, PRECURSOR SOLUTION, AND METHOD FOR PRODUCING ION CONDUCTOR
To provide an ion conductor having improved lithium ion conductivity in an oxide based on a β-Li3 PO4 type crystal structure.SOLUTION: The object can be achieved by an ion conductor having a β-Li3 PO4 type crystal phase as a main phase and containing Li, M element, P or Si as constituent elements, where M element is one or more elements selected from Al, Mg, Ga and Ge. It is particularly preferable that the composition has an M/(M+P) atomic ratio or (M+Si)/(M+Si+P) atomic ratio of 0.01 to 0.80 and a Li/(M+P) atomic ratio or Li/(M+Si+P) atomic ratio of 2.00 to 3.50.SELECTED DRAWING: Figure 1
【課題】β－Ｌｉ３ＰＯ４型の結晶構造を基本とする酸化物において、リチウムイオン伝導性を改善したイオン伝導体を提供する。【解決手段】上記課題は、β－Ｌｉ３ＰＯ４型構造の結晶相を主相に持ち、Ｌｉ、Ｍ元素、Ｐ、あるいは更にＳｉを構成元素に含むイオン伝導体によって達成できる。ここで、Ｍ元素はＡｌ、Ｍｇ、Ｇａ、Ｇｅから選ばれる１種以上の元素である。Ｍ／（Ｍ＋Ｐ）原子比あるいは（Ｍ＋Ｓｉ）／（Ｍ＋Ｓｉ＋Ｐ）原子比が０.０１以上０.８０以下、Ｌｉ／（Ｍ＋Ｐ）原子比あるいはＬｉ／（Ｍ＋Ｓｉ＋Ｐ）原子比が２.００以上３.５０以下である組成を有するものが特に好ましい。【選択図】図１
