Abstract

La presente invención se refiere a un proceso para formar un cátodo electroquímico que comprende: a) mezclar una suspensión espesa de partículas de carbono con una solución de sal de plata a fin de formar una suspensión de plata de partículas de carbono que contienen plata, b) impregnar una cinta continua fibrosa no tejida conductora con una dispersión que commprende partículas de carbono que contienen plata y un material polimérico no fibroso, para retener las partículas de carbono que contienen plata en la cinta continua; y c) laminar un substrato recolector de corriente en la cinta continua impregnada para formar el cátodo electroquímico.
