Abstract
【解決手段】昇温脱離ガス分析において、200〜800℃の温度範囲で検出されるH2Oガス発生量が680ppm以下であることを特徴とするSiOx。H2Oガス発生量は420ppm以下であることが望ましい。また、X線回折により得られたグラフにおいて、2θ=28°付近に発生するSiピーク点におけるピーク強度P1と、ピーク点前後の平均勾配から想定したピーク点におけるベース強度P2が、(P1−P2)/P2≦0.2を満足することが望ましい。

Description
Si−OH + HO−Si → −Si−O−Si− + H2O↑ …(1)
(1)Si粉末とSiO2粉末とを混合し、造粒した混合造粒原料を1100〜1350℃に加熱する。この場合、前掲の特許文献1に記載されるように、水素ガス含有量の低い原料を用いることが、スプラッシュ発生数を低減する上で望ましい。
SiOxの用途がバリアフィルム用蒸着材の場合は、通常、xが1より大きいSiOxとし、リチウムイオン二次電池用負極活物質として使用する場合は、一般に、xが1より小さいSiOxとする。このxの値は、例えば、SiとSiO2の2種類の原料を個別の熱源で独立して加熱して蒸着させる二元蒸着法で作製したSiOx膜を粉末化してSiOx粉末を製造する場合に、SiOx膜を作製する際のSiとSiO2の各蒸着速度を調整することによって、調整することができる。
(3)SiOxを析出させた析出基体をAr雰囲気中で冷却し、SiOxを回収し、粉末化する。
(4)回収したSiOxと、適量のエタノールをオートクレーブ内に収容し、圧力を0.1〜1MPa、温度を80〜150℃で処理する。
・昇温脱離ガス分析において200〜800℃の温度範囲で検出されるH2Oガス発生量
昇温脱離ガス分析装置を使用し、SiOxを室温から0.5℃/sの昇温速度で昇温し、Mass Fragment法によって測定した。
・SiOxのx値
SiOxのO(酸素)をセラミック中酸素分析装置(不活性気流下溶融法)によって定量し、SiOxのSiを、SiOxを溶液化した後、ICP発光分光分析(誘導結合高周波プラズマ分光分析)によって定量し、両定量値からSiOxのx値を算出した。
粉末X線回折装置を用いてX線の入射角と回折強度との関係を調査した。試料には、上記方法で製造したSiOxを平均粒径20μmに粉砕したものを使用した。X線回折の測定条件は表2に示すとおりとした。そして、Siピーク点におけるピーク強度P1からベース強度P2を減じた値P1−P2とベース強度P2との比(強度比(P1−P2)/P2)を求めた。この強度比の求め方は上述のとおりである。
イオンプレーティング装置を用いて、昇華したSiOxが析出基体に蒸着する際に、エレクトロンビームを、出力が300W、初期圧力が4×10-4Paのもとで60秒間照射した場合に発生するスプラッシュの個数を測定した。
SiOxを負極活物質として使用したリチウムイオン二次電池を作製し、一定の電流で充電、放電を行い、初期効率を求めた。
