[化学式1]
Li6PS5X
式中、XはCl、BrまたはIである。
(S1)単体硫黄粉末(シグマアルドリッチ社製、sulfur)、単体リン粉末(シグマアルドリッチ社製、phosphorous)、単体リチウム粉末(FMC社製、Lithium powder)及び塩化リチウム粉末(シグマアルドリッチ社製、LiCl)を混合して混合粉末を得た。

Li6PS5Cl
前記実施例の固体電解質を含み、陽極、陰極、及び前記陽極と前記陰極との間に位置する固体電解質層から構成された全固体電池を製造した。
出発物質として、単体ではなく、化合物(Li2S、P2S5、LiCl)を使用した。
前記実施例で製造した固体電解質に対するX線回折分析(X-ray diffraction spectroscopy)を行った。その結果は図3のとおりである。これを参照すると、2θ=15.5±1°、18±1°、26±1°、30.5±1°、32±1°で主要なピークが観察され、これはアルジロダイト型結晶構造のピークと全て一致するので、前記固体電解質がアルジロダイト型結晶構造を持っていることが分かる。
前記実施例で製造した固体電解質を圧縮成形して測定用成形体(直径13mm、厚さ0.6mm)を作った。前記成形体の10mVの交流電位を与えた後、1×106乃至100Hzの周波数掃引を行ってインピーダンス値を測定したので、前記固体電解質のリチウムイオン伝導度は2.3×10-3S/cmと非常に高かった。よって、本発明の製造方法によれば、高イオン伝導性の固体電解質を得ることができる。
前記製造例及び比較例の全固体電池それぞれに対して0.1Cレートの律速で2.5V~4.3Vの範囲のCC(Constant current)条件で充放電を行って充電容量及び放電容量を測定した。その結果は図4のとおりである。これを参照すると、前記製造例と比較例の全固体電池の充電容量、放電容量及び効率が下記表1のとおりであることが分かる。
