processing method:以下、UC処理という)等、ずり応力、遠心力、その他の機械的エネルギーを加えることができればよい。要するに、機械的エネルギーによって、導電性炭素材料にバナジウム化合物を付着させ、導電性炭素材料の表面上でリン酸バナジウムリチウムの前駆体を生成できればよい。このメカノケミカル処理は、少なくとも2回の処理に分けてもよく、第1回目の処理では、バナジウム源と導電性炭素材料とにずり応力と遠心力を加えて、導電性炭素材料にバナジウム化合物を付着させ、第2回目の処理では、リン酸源を加えた上でずり応力と遠心力を追加し、導電性炭素材料の表面上でリン酸バナジウムリチウムの前駆体を生成することができる。
force processing method:以下、UC処理という)等、ずり応力、遠心力、その他の機械的エネルギーを加えることができればよい。要するに、機械的エネルギーによって、導電性炭素材料にバナジウム化合物を付着させ、導電性炭素材料の表面上でリン酸バナジウムリチウムの前駆体を生成できればよい。メカノケミカル処理は、リチウム源、バナジウム源、リン酸源、及び導電性炭素材料の微細化と高分散化処理を兼ねることもできる。
本実施例では、以下の製造手順により、リン酸バナジウムリチウムとカーボンナノファイバ(以下、CNFという)のコンポジット材料(以下、Li3V2(PO4)3/CNFという)を生成した。
本実施例では、以下の製造手順により、リン酸バナジウムリチウムとケッチェンブラックとが複合化されたコンポジット材料(以下、Li3V2(PO4)3/KBという)を生成した。
以上のように、本実施形態に係るリン酸バナジウムリチウムと導電性炭素材料の複合体は、リン酸バナジウムリチウムは導電性炭素材料の表面に結合してなることにより、良好な高放電容量、特に高Cレートでの高放電容量、及び良好な耐劣化性を有し、蓄電デバイスとして実用的であり、特に電気化学キャパシタとして最適である。特に、リン酸バナジウムリチウムとしてプレート形状の結晶体と粒子形状の結晶体が混在していることにより、高Cレートでの飛躍的な高放電容量が達成される。
