CM組成物を実施例1において上記したように製造した。製造後、様々な重量パーセントの水素フォスフェート(H3PO4)をCM組成物と混合した。具体的には、10重量%のリン酸水素、15重量%の水素フォスフェート、20重量%の水素フォスフェート、および30重量%の水素フォスフェートとCMを混合した。この組成物を1時間高エネルギー粉砕することによってナノ複合材料を形成し、その後組成物をアルゴン中250℃で30分間アニールした。上記したように、この組成物を電極に加工し、評価のために電気化学セルを二通り(a、b)で組み立てた。セルを24℃において7.58mA/gで放電させ、得られた電圧プロファイルおよび容量を図8に示す。図8でわかるように、比容量は、組成物全てについて高く、多くの組成物は複合材料全体の重量に基づいて325mAh/g超を達成した。
