Abstract

Los tamanos de las pilas que se comercializan en el mercado son fijos, por lo que se ha considerado apropiado intentar incrementar la capacidad, es decir,la vida util de la pila, aumentando el área de superficie del material activo electrodico yempa quetando cantidades más importantes de material activo en lamisma. Esta aproximacion presenta limitaciones prácticas. Si el material activo es empaquetado muy densamente en la pila, es posible que se reduzca lavelocidad de la reaccionelectroquímica durante la descarga, reduciéndose a su vez la vida util. Es posible que se produzcan otros efectos perjudiciales comola polarizacion, particularmente bajo altas descargas de corriente (aplicaciones de alto consumo). La resistencia alcontacto entre e l material catodico activode MnO2 y la carcasa de la pila alcalina también reduce la vida util. Existe una necesidad en expansion a nivel comercial de contar con pilas alcalinasprimarias más adecuadas para aplicaciones de altoconsumo. Por ello, es c onveniente proveer una manera de extender de un modo confiable la vida util de laspilas alcalinas primarias convencionales particularmente de aquellas a ser utilizadas en aplicaciones de alto consumo, sin aumentarsignificativamente losefectos de pol arizacion u otros que afecten de manera adversa el rendimiento de las mismas. Una pila electroquímica que comprende un ánodo que contiene zinc,una solucion de electrolito alcalino acuosa, un separador y un cátodoque contiene dioxido de manganeso, en el cual dicho ánodo además incluye un polvometálico conductor de la electricidad mezclado físicamente con el zinc. El polvo metálico conductor es seleccionado preferentemente del grupo integrado porestano,cobre, palta, magnesio, indio y bismuto, y combinaciones de los mismos. Preferentemente el cátodo comprende dioxido de manganeso electrolítico (EMD);la solucion de electrolito acuosa comprende hidroxido de potasio; el ánodo comprende entreaproximadamente 0,2 y 0,3% en peso de polvo de estano ; el contenidototal de mercurio es inferior a 50 ppm con relacion a su peso total y el contenido total de plomo es inferior a 30 ppm con relacion al contenido total de metal
