Abstract
(EN) An electrode-forming material in which 0.5 to 10 parts by mass of carbon nanofibers with respect to 100 parts by mass of electrode active material cover from 40 to 80% of the electrode active material surface in a mesh-structure to form a conductive layer. Preferably, the carbon nanofiber surface has been oxidized, and the oxygen content due to the oxidation is controlled to 8 to 20 mass%.
(FR) La présente invention concerne un matériau de formation d'électrode dans lequel 0,5 à 10 parties en masse de nanofibres de carbone par rapport à 100 parties en masse de matériau actif d'électrode couvrent de 40 à 80 % de la surface de matériau actif d'électrode dans une structure maillée afin de former une couche conductrice. De préférence, la surface de nanofibres de carbone a été oxydée et la teneur en oxygène due à l'oxydation est contrôlée comme représentant de 8 à 20 % en masse.
(JA)  この電極形成材は、電極活物質100質量部に対して0.5~10質量部のカーボンナノファイバーによって電極活物質表面の40~80%が網目状に被覆されることによって導電層が形成されている。好ましくは、カーボンナノファイバーの表面が酸化処理されており、該酸化処理による酸素含有量が8~20質量%に制御されている。
