CARBON NANOTUBE ELECTRODE, POWER STORAGE DEVICE USING THE SAME, AND MANUFACTURING METHOD OF CARBON NANOTUBE COMPOSITE

To provide a carbon nanotube electrode that can improve negative electrode capacity, a power storage device using the same, and a manufacturing method of a carbon nanotube composite.SOLUTION: A carbon nanotube electrode includes multi-walled carbon nanotubes formed on a conductive substrate. The multi-walled carbon nanotube includes a main body having a plurality of tubular graphene sheets arranged concentrically, and a surface layer portion that has a plurality of graphene sheets having different physical properties from the tubular graphene sheets that overlap the outside of the main body, and in which a carbon ring deficient portion which is a part where the carbon ring of the graphene sheet is defective is larger than the main body.SELECTED DRAWING: Figure 3 【課題】負極容量を向上することができるカーボンナノチューブ電極及びこれを用いた蓄電デバイス並びにカーボンナノチューブ複合体の製造方法を提供する。【解決手段】カーボンナノチューブ電極は、導電性基材に形成された多層カーボンナノチューブを含む。多層カーボンナノチューブは、同心円状に配置された複数のチューブ状のグラフェンシートを含む主体部と、主体部の外側に重なるチューブ状のグラフェンシートとは物性の異なるグラフェンシートを複数含み、グラフェンシートの炭素環が欠損した部分である炭素環欠損部が主体部に比べて多い表層部と、を含む。【選択図】図３
