Zusammenfassung:To provide a higher conductivity of lithium-ion conductive glass-ceramics, a solid electrolyte and a battery.SOLUTION: There is provided a method for producing a solid electrolyte comprising lithium-ion conductive glass-ceramics. The method includes the following steps of: providing at least one lithium ion conductor having a ceramic phase content and amorphous phase content; providing a powder of the at least one lithium ion conductor, the powder having a polydispersity index between 0.5 and 1.5, preferably between 0.8 and 1.3, and more preferably between 0.85 and 1.15; and a) incorporating the powder into a polymer electrolyte or a polyelectrolyte and/or b) forming an element using the powder.SELECTED DRAWING: Figure 1 【課題】リチウムイオン伝導性ガラスセラミック、固体電解質および電池のより高い伝導率を提供する。【解決手段】前記の課題は、リチウムイオン伝導性ガラスセラミックを含む固体電解質の製造方法であって、以下の段階:・ セラミック相含分とアモルファス相含分とを有する少なくとも1つのリチウムイオン伝導体を準備する段階、・ 前記少なくとも1つのリチウムイオン伝導体の粉末を準備し、前記粉末は0.5~1.5、好ましくは0.8~1.3、好ましくは0.85~1.15の多分散度指数を有する段階、およびa) 前記粉末をポリマー電解質または多価電解質中に混入する段階、且つ/またはb) 前記粉末を使用してエレメントを成形する段階を含む前記方法によって解決される。【選択図】図1
