Abstract
【解決手段】グラフェン中に、環員数が9以上の炭素環を設ける。環員数が9以上の炭素環は、リチウムイオンに対する最大ポテンシャルがほぼ0電子ボルトであるため、リチウムイオンが透過する間隙として機能させることができる。このようなグラフェンを電極や活物質表面に被覆すると、リチウムイオンの移動を妨げずに、電極や活物質と電解液との反応を抑制できる。
【選択図】図3
Description
本実施の形態では、グラフェンに設ける間隙の大きさ、間隙の数密度(グラフェン単位面積あたりの間隙の数)、及びグラフェンの機械的強度を最適なものとする方法について説明する。
本実施の形態では、シリコン粒子の表面にグラフェンを1層以上50層以下有するグラフェン層を形成する例について説明する。最初に、グラファイトを酸化して、酸化グラファイトを作製し、これに超音波振動を加えることで酸化グラフェンを得る。詳細は特許文献2を参照すればよい。また、市販の酸化グラフェンを利用してもよい。
本実施の形態では、集電体上に形成されたシリコン活物質層の表面にグラフェンを1層以上50層以下有するグラフェン層を形成する例について説明する。最初に、酸化グラフェンを水やNMP等の溶媒に分散させる。溶媒は極性溶媒であることが好ましい。酸化グラフェンの濃度は1リットル当たり0.1g乃至10gとすればよい。
本実施の形態では、集電体上に形成されたシリコン活物質層の表面にグラフェンを1層以上50層以下有するグラフェン層を形成する別の例について説明する。実施の形態2と同様に、酸化グラフェンを水やNMP等の溶媒に分散させる。グラフェンの濃度は1リットル当たり0.1g乃至10gとすればよい。
本発明の一態様に係る蓄電装置は、電力により駆動する様々な電気機器の電源として用いることができる。
