    Abstract: 1. Procedimiento para fabricar un material activo de electrodo revestido, en el que dicho procedimiento comprende las siguientes etapas: (a) proporcionar un material activo de electrodo particulado según la fórmula general Li1+xTM1-xO2, en la que TM es una combinación de Ni, Co y, opcionalmente, Mn, y, opcionalmente, al menos un metal seleccionado entre Mg, Al, Ba, Ti y Zr, y x está en el intervalo de cero a 0,2, en el que al menos el 15 % en moles del metal de transición de TM es Ni, (b) tratar dicho material activo de electrodo con un compuesto de M1, en el que M1 se selecciona entre Li, Al, B, Mg, Si, Sn y entre metales de transición, o una combinación de al menos dos de los anteriores, con o sin un disolvente, en el que dicho compuesto de M1 no actúa como material activo de cátodo por sí mismo, (c) opcionalmente, eliminar el compuesto de M1 que no se deposita sobre dicho material activo de electrodo particulado, (d) realizar un postratamiento calentando el material obtenido después de la etapa (b) o (c), en su caso, a una temperatura de 250 a 950°C en lecho fluidizado.
