Description
負極として使用するIn箔(厚み0.05mm)をφ13(mm)で打ち抜き、セル容器にセットした。その上に固体電解質であるLi2S−P2S5(80−20mol%)(SE)をメカニカルミリング処理(MM処理)したものを80mg積層し、成型機で軽く表面を整えた。更に、正極活物質としてコバルト酸リチウム(LiCoO2)粒子をエタノール中に分散し、ここにアルミニウムイソプロポキシドをAl添加量0.05wt%になるように溶解した後熱処理することにより、Li−Al−Oの結合を有するリチウムアルミニウム酸化物で被覆された表面処理正極活物質を得た。そして、表面処理正極活物質と、SEと、導電剤である気相成長カーボンファイバ(VGCF)とを60/35/5wt%の比率で混合したものを、正極合剤としてSEの上に積層した。その状態で3t/cm2の圧力で加圧しペレットを作製し試験用セルを得た。
表面処理正極活物質に、Al添加量が0.1wt%になるものを使用したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
表面処理正極活物質に、Al添加量が0.2wt%になるものを使用したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
表面処理正極活物質に、Al添加量が0.5wt%になるものを使用したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
アルミニウムイソプロポキシドに代えてホウ素プロポキシドを使用し、表面処理正極活物質に、B添加量が0.1wt%になるものを使用したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
アルミニウムイソプロポキシドに代えてガリウムイソプロポキシドを使用し、表面処理正極活物質に、Ga添加量が0.1wt%になるものを使用したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
正極活物質に表面処理を行わなかったこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
正極活物質の表面処理を行わずに、Al添加量が0.05wt%になるように酸化アルミニウムを正極作成時に混合したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
正極活物質の表面処理を行わずに、Al添加量が0.5wt%になるように酸化アルミニウムを正極作成時に混合したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
正極活物質の表面処理を行わずに、B添加量が0.5wt%になるように酸化ホウ素を正極作成時に混合したこと以外は実施例1と同様にして試験用セルを作製し、電池特性を評価した。
