Abstract

UN MATERIAL CATODICO, ACTIVO COMPRENDE UNA MEZCLA DE PARTICULAS DE GRAFITO Y PARTICULAS DE DIOXIDO DE MANGANESO ELECTROLITICO QUE SE COMPONE DE CRISTALES EN FORMA DE AGUJA QUE TIENEN UNA PROPORCION DE ASPECTO QUE OSCILA ENTRE 2 Y 20 Y UNA PILA ALCALINA DE DIOXIDO DE MANGANESO ESTA PROVISTA DE UN CATODO PREPARADO A PARTIR DEL MATERIAL CATODICO, ACTIVO. EL MATERIAL CATODICO, ACTIVO PARA PILAS SECAS PUEDE PREPARARSE MEZCLANDO, DE ANTEMANO, POLVO DE CARBON CON POLVO DE DIOXIDO DE MANGANESO EN UNA PROPORCION DE PESO QUE OSCILA ENTRE 1:100 Y 15:100 Y PULVERIZANDO POSTERIORMENTE LA MEZCLA RESULTANTE. EL NUEVO MATERIAL CATODICO, ACTIVO PARA PILAS SECAS PERMITE UNA MEJORA SUBSTANCIAL DE LA PILA SECA RESULTANTE CON UNA ALTA CALIDAD DE CARGA-DESCARGA.
