Description
ケイ素酸化物の表面に炭素を被覆させるステップ;及び
前記炭素が被覆されたケイ素酸化物とリチウム酸化物を混合した後、非活性雰囲気で熱処理するステップを含むケイ素系複合体の製造方法を提供する。
実施例1 :ケイ素系複合体の製造
一酸化ケイ素の表面に炭素被覆ステップ(1)
ケイ素酸化物として一酸化ケイ素20gを回転管状炉に投入し、アルゴンガスを0.5L/分で流した後、温度を5℃/分の速度で1000℃まで昇温させた。回転管状炉を10rpm/分の速度で回転させながらアルゴンガスを1.8L/分、アセチレンガスを0.3 L/分で流しながら、3時間の間800℃で熱処理して炭素が被覆された一酸化ケイ素を製造した。このとき、炭素含有量はケイ素酸化物に対して5重量部であった。
炭素が被覆された一酸化ケイ素に比べリチウムの量が7重量部となるようにLi2Oの量を調節して、炭素が被覆された一酸化ケイ素とLi2O粉末をすり鉢で均等に混合した。Li2O粉末の場合、白色を帯びるので、均等に混合したときに全体的に粉末は灰色を帯びた。前記混合された粉末をアルミナるつぼに移し、前記るつぼをファーネスに入れ、Arガスを100cc/minの流量で供給しながら常温で900℃まで10℃/minの速度で加熱した後、900℃で5時間保持させ、10℃/minで冷却させてケイ素複合体を製造した。
一酸化ケイ素の表面に炭素を被覆するステップ(1)を行っていないことを除いては、前記実施例1と同一の方法で一酸化ケイ素とリチウム酸化物を混合して熱処理し、一酸化ケイ素にリチウムが結合されたケイ素系複合体を製造した。
一酸化ケイ素とリチウム酸化物を混合するステップ(2)を行っていないことを除いては、前記実施例1と同一の方法で一酸化ケイ素の表面に炭素をコーティングし、炭素被覆された一酸化ケイ素系複合体を製造した。
負極活物質として前記実施例1で製造したケイ素系複合体と、導電材のアセチレンブラック及びバインダーのポリビニリデンフルオリドを85:5:10の重量比で混合し、これらを溶媒であるN−メチル−2−ピロリトンに混合してスラリーを製造した。製造されたスラリーを銅集電体の一面に65μmの厚さでコーティングして乾燥し圧延した後、一定の大きさにパンチングして負極を製造した。
前記実施例1のケイ素系複合体の代わりに、前記比較例1のケイ素系複合体を使用することを除いては、前記実施例2と同一の方法でコイン型二次電池を製造した。
前記実施例1のケイ素系複合体の代わりに、前記比較例2のケイ素系複合体を使用することを除いては、前記実施例2と同一の方法でコイン型二次電池を製造した。
前記実施例2及び比較例3及び4で製造されたそれぞれの二次電池の初期効率を調べるため、最初のサイクル充電容量及び最初のサイクル放電容量を測定した後、最初のサイクル充電容量に対する最初のサイクル放電容量の比(初期効率)を下記の表1に示した。
