Abstract

3(57)METODO PARA MEJORAR LA COMPACTACION DE UN CATODO PARA UNA PILA ELECTROQUIMICA.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UNA MEZCLA CONSTITUIDA POR UN MATERIAL ACTIVO DE CATODO FORMADO POR PARTICULAS Y POR UN MATERIAL ELECTRONICAMENTE CONDUCTOR FORMADO TAMBIEN POR PARTICULAS; SEGUNDA, SE AÑADE A DICHA MEZCLA UNA POLIOLEFINA CONSTITUIDA POR PARTICULAS EN UNA CANTIDAD COMPRENDIDA ENTRE 0,1 Y UN 3 DE DICHO CATODO; Y POR ULTIMO, SE REALIZA LA COMPACTACION, MEDIANTE UNA EXTRUSION DE LA MEZCLA FORMADA, EN EL INTERIOR DE UN RECIPIENTE DE LA PILAELECTROQUIMICA. LA POLIOLEFINA UTILIZADA SE SELECCIONA DEL GRUPO CONSTITUIDO POR POLIETILENO Y POLIPROPILENO Y EL MATERIAL CONDUCTOR SE SELECCIONA DEL GRUPO CONSTITUIDO POR GRAFITO Y CARBONO.
