Title (EN) CURRENT COLLECTOR-CATALYST MONOLITHIC THREE-DIMENSIONAL NANOFIBER NETWORK FOR LI-AIR BATTERIES AND MANUFACTURING METHOD THEREOF
(FR) COLLECTEUR DE COURANT-CATALYSEUR BASÉ SUR UN RÉSEAU DE NANOFIBRES TRIDIMENSONNEL MONOLITHIQUE POUR BATTERIES LI-AIR ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) Disclosed is an electrode for lithium-air batteries without using a binder and a carbon additive and a method of manufacturing the same, and more specifically, provided is a nanofiber network-based current collector-catalyst monolithic porous air electrode which has an improved specific surface area and high air permeability as the energy density per weight is increased and the diameter, porosity, and thickness of the nanofibers are controlled by utilizing a significantly light polymer and carbon based material.
(FR) L'invention concerne une électrode pour des batteries lithium-air sans liant ni additif de carbone, et son procédé de fabrication, et plus spécifiquement, l'invention concerne une électrode-air poreuse monolithique à collecteur de courant-catalyseur basée sur un réseau de nanofibres qui présente une meilleure surface spécifique et une haute perméabilité à l'air au fur et à mesure que la densité d'énergie par poids augmente et que le diamètre, la porosité et l'épaisseur des nanofibres sont régulés au moyen d'un matériau à base de carbone et de polymère sensiblement léger.
