Abstract

SE PROPORCIONAN ELECTRODOS POROSOS PARA BATERIAS DE ACUMULADORES DE PLOMO-ACIDO, SIN PLACAS O REJILLAS DE SOPORTE, QUE PRESENTAN CARACTERISTICAS DE COMPORTAMIENTO FUNCIONAL MEJORADAS EN COMPARACION CON LAS BATERIAS CONVENCIONALES DE PLOMO-ACIDO. LOS ELECTRODOS SE FABRICAN FORMANDO UNA MEZCLA FUNDIDA DE UN METAL (POR EJEMPLO, PLOMO) Y UN COMPONENTE DE FORMACION DE POROS (POR EJEMPLO, CADMIO), ENFRIANDO Y CONVIRTIENDO LA MEZCLA FUNDIDA EN UN ELECTRODO SOLIDO CON LE COMPONENTE DE FORMACION DE POROS DISTRIBUIDO A SU TRAVES, RETIRADO EL COMPONENTE DE FORMACION DE POROS DESDE EL ELECTRODO SOLIDO PARA DEJAR UNA RED DE HUECOS QUE DEFINE LOS POROSL Y OXIDADO LAS PAREDES METALICAS DENTRO DE LOS POROS PARA FORMAR UN REVESTIMIENTO DE MATERIAL ELECTROQUIMICAMENTE ACTIVO (POR EJEMPLO, DIOXIDO DE PLOMO) SOBRE LAS PAREDES DENTRO DE LOS POROS.POROUS ELECTRODES ARE PROVIDED FOR LEAD-ACID ACCUMULATOR BATTERIES, WITHOUT SUPPORT PLATES OR GRIDS, WHICH HAVE IMPROVED FUNCTIONAL BEHAVIOR FEATURES AS COMPARED TO CONVENTIONAL LEAD-ACID BATTERIES. ELECTRODES ARE MANUFACTURED BY FORMING A CAST MIXTURE OF A METAL (FOR EXAMPLE, LEAD) AND A PORE FORMING COMPONENT (FOR EXAMPLE, CADMIUM), COOLING AND CONVERTING THE MELTING MELTED INTO A SOLID ELECTRODE BY LE COMPONENT OF FORM ITS TRAVES, WITHDRAWED THE PORE FORMATION COMPONENT FROM THE SOLID ELECTRODE TO LEAVE A NETWORK OF HOLES THAT DEFINES THE POROSL AND OXIDIZED THE METALLIC WALLS INSIDE THE PORES TO FORM A COATING OF ELECTROCHEMICALLY ACTIVE MATERIAL (FOR EXAMPLE), FOR EXAMPLE, AN EXEMPTION OF ELECTROCHEMICALLY ACTIVE PLANT. THE WALLS INSIDE THE PORES.
