Abstract

La presente invencion se refiere a pilas alcalinas que contienen un material activo del cátodo, de dioxido de magnesio. Una sustancia seleccionada del grupo de los compuestos de CaWO4, BatiO3, CatiO3, ZnMn2O4, o Bi12TiO26, o cualquier otra combinacion de los mismos, es agregada al cátodo de las pilas alcalinas convencionales que tienen típicamente un ánodo que comprende zinc y un cátodo que comprende dioxido de manganeso y un electrolito alcalino. El aditivo incrementa la duracion en servicio de la pila.
