Abstract

ESTA INVENCION SE REFIERE A PILAS DE DIOXIDO DE MANGANESO RECARGABLES (10, 40) QUE TIENEN ELECTROLITOS ALCALINOS, ELECTRODOS NEGATIVOS DE CINC (14) Y ELECTRODOS POSITIVOS DE DIOXIDO DE MANGANESO (18). SEGUN LA PRESENTE INVENCION, EL ELECTRODO POSITIVO SE ENCUENTRA ESENCIALMENTE LIBRE, ES DECIR NO SE UTILIZA NINGUNA JAULA EN LA PILA PARA CONFINAR AL ELECTRODO POSITIVO. DURANTE LA DESCARGA DE LA PILA ALCALINA RECARGABLE, EL ELECTRODO POSITIVO SE PUEDE INCLINAR AUMENTANDO DE VOLUMEN Y DURANTE EL CICLO DE CARGA SE PUEDE INCLINAR CONTRAYENDOSE O REDUCIENDO SUS DIMENSIONES. SI EMBARGO, EL ELECTRODO POSITIVO SE DIMENSIONA DE TAL MODO QUE OCUPE SUSTANCIALMENTE TODO EL ESPACIO A EL ASIGNADO DENTRO DE LA PILA, AL TIEMPO QUE QUEDA UN PEQUEÑO ESPACIO PARA LA EXPANSION O CRECIMIENTO A LO ALTO O A LO LARGO DE LAS PILAS DE BOBINA. EL ELECTRODO POSITIVO PUEDE INCLUIR ADITIVOS TALES COMO CARBON O GRAFITO PARA AUMENTAR SU CONDUCTIVIDAD ELECTRICA Y AGENTES HIDROFOBOS TALES COMO PTFE, POLIETILENO O POLIPROPILENO PARA AUMENTAR LA PERMEABILIDAD AL HIDROGENO DEL ELECTRODO POSITIVO Y ASI MAYORES VELOCIDADES DE RECOMBINACION DEL HIDROGENO. ADEMAS, LA CAPACIDAD DE DESCARGA DEL ELECTRODO NEGATIVO SE PUEDEN ESTABILIZAR DE MODO QUE SE ENCUENTREN DENTRO DE LA GAMA DEL 60% APROXIMADAMENTE AL 120% APROXIMADAMENTE DE LA CAPACIDAD DE DESCARGA TEORICA DE UN ELECTRON DEL ELECTRODO DE MNO{SUB,2} POSITIVO.
