Description
これら電気化学素子の電解質として用いることで、耐湿性を向上した電気化学素子を提供することができる。電解質以外の構成部材については、周知の材料を適宜用いることができる。
硫化リチウム(フルウチ化学製)0.792gと、硫化リン(Aldrich製)0.639gと、硫化ビスマス(高純度化学製)0.740gを用意した。これらを露点が−40℃以下のアルゴン雰囲気下において、遊星型ボールミルで370rpmの条件で20時間混合粉砕することで硫化物固体電解質材料を得た。得られた硫化物固体電解質材料のX線回折を測定したところ、そのほとんどが非晶質であった。
実施例2〜4、6〜11、14〜18は、硫化リチウム、硫化リン、硫化ビスマスのLi,P,Biの元素の組成比を、表1に示すような組成比に変えたこと以外は実施例1と同様にして得た。
実施例5は、露点が−40℃以下のアルゴン雰囲気下において、290℃で1時間熱処理したこと以外は実施例4と同様にして得た。実施例12は、露点が−40℃以下のアルゴン雰囲気下において、270℃で1時間熱処理したこと以外は実施例11と同様にして得た。また、実施例13は露点が−40℃以下のアルゴン雰囲気下において、380℃で1時間熱処理したこと以外は実施例11と同様にして得た。
比較例1〜8は、硫化リチウム、硫化リン、硫化ビスマスのLi,P,Biの元素の組成比を、表1に示すような組成比に変えたこと以外は、実施例1と同様にして得た。
得られた実施例1〜18、比較例1〜8の硫化物固体電解質材料を、それぞれ露点が−40℃以下のアルゴン雰囲気下で2mLのバイアルに50mg秤量した。この固体電解質を大気下で500mLのビーカー内に配置し、ビーカーにふたをした。10分間放置させることで、ビーカー内の水分と固体電解質を反応させ、硫化水素を発生させた。検知管式気体測定器GV−100S(ガステック製)と硫化水素検知管4LB(ガステック製)を用いて、ビーカー内の硫化水素濃度を0.5〜12ppmの濃度範囲で測定した。
