Provided is a 3LiOH·Li2SO4 solid electrolyte with which a reduction in lithium ion conductivity is significantly inhibited, even after long-term storage at a high temperature. This solid electrolyte is identified as 3LiOH·Li2SO4 by X-ray diffraction and further contains boron. L'invention concerne un électrolyte solide 3 LiOH · Li 2 SO 4 avec lequel une réduction de la conductivité des ions lithium est significativement inhibée, même après un stockage à long terme à haute température. Cet électrolyte solide est identifié comme 3 LiOH · Li 2 SO 4 par diffraction des rayons X et contient en outre du bore. 高温で長時間保持した後においてもリチウムイオン伝導度の低下を有意に抑制可能な３ＬｉＯＨ・Ｌｉ２ＳＯ４ベースの固体電解質が提供される。この固体電解質は、Ｘ線回折により３ＬｉＯＨ・Ｌｉ２ＳＯ４と同定されるものであり、ホウ素をさらに含むものである。
