Abstract:
(EN) The present invention relates to a composition for producing an anode for an electricity storage device, wherein the composition comprises an anode active material, a conductive agent, a carbon nanofiber produced by electrospinning a solution containing a carbon fiber precursor, and a binder. The present invention also relates to an anode for an electricity storage device made with the composition, and to an electricity storage device comprising the anode. The composition for producing the anode is characterized in that a portion or the entirety of conventional conductive agents, dispersing agents, and/or binders is replaced by the carbon nanofiber, to thereby significantly improve the specific surface area and electrical conductivity of the anode (i.e. reduce resistance), and thus maximize the efficiency and capacity of the anode active material.
(FR) La présente invention concerne une composition pour produire une électrode positive pour un dispositif de stockage d'énergie électrique, la composition comprenant un matériau actif d'électrode positive, un agent conducteur, une nanofibre de carbone produite par électrofilage d'une solution contenant un précurseur de fibre de carbone et un liant. La présente invention concerne également une électrode positive pour un dispositif de stockage d'énergie électrique produite au moyen de la composition et un dispositif de stockage d'énergie électrique comprenant l'électrode positive. La composition pour produire une électrode positive pour un dispositif de stockage d'énergie électrique est caractérisée en ce qu'une partie ou l'intégralité des agents conducteurs, des agents dispersants et/ou des liants classiques est remplacée par la nanofibre de carbone, pour améliorer de ce fait de manière significative l'aire de surface spécifique et la conductivité électrique de l'électrode positive (c'est-à-dire pour réduire la résistance), et ainsi augmenter à un maximum le rendement et la capacité du matériau actif d'électrode positive.
