Abstract

UN METODO MEJORADO PARA LA FABRICACION CONTINUA DE ELECTRODOS NEGATIVOS, ALMACENANDO ALEACIONES DE HIDROGENO ELECTROQUIMICO, DE HIDRURO METALICO PARA USAR EN CELULAS RECARGABLES DE HIDRURO METALICO DE NIQUEL. EL METODO MEJORADO COMPRENDE LOS PASOS DE PROVEER CANTIDADES MEDIDAS DE HIDRURO METALICO EN POLVO ALMACENANDO MATERIAL (39) DE ALEACIONES DE HIDROGENO ELECTROQUIMICO Y DISPONIENDO DICHO MATERIAL SOBRE UN SUBSTRATO CONTINUO CONDUCTOR CONECTADO A UNA PANTALLA (40). DESPUES DE ESTO, EL HIDRURO METALICO ALMACENANDO ALEACIONES DE HIDROGENO ELECTROQUIMICO Y EL CONDUCTOR CONECTADO A LA PANTALLA SE SOMETEN A UN PROCESO DE COMPACTACION EN DONDE SON APLANADOS (50,60) Y PRESIONADOS DE MODO QUE FORMAN UNA UNICA TRAMA DE ELECTRODO INTEGRAL LA CUAL SE EXPONE A CONTINUACION A UN PROCESO DE INCRUSTACION A ALTA TEMPERATURA (80) EN UN ENTORNO QUIMICAMENTE INERTE. EL PROCESO DE INCRUSTACION ESTA DISEÑADO PARA EXPULSAR EL EXCESO DE HUMEDAD DEL MATERIAL IMPIDIENDO LA OXIDACION DE LA TRAMA DE LOS ELECTRODOS Y ESTABLECE EL ESTADO DE CARGA DEL ELECTRODO.
