Abstract

Un electrodo magnético rico en litio, un método de preparación para este y su uso. El electrodo magnético rico en litio comprende un colector de corriente y una capa de sustancia activa dispuesta sobre una superficie del colector de corriente, la capa de sustancia activa comprende un material activo de electrodo, una sustancia magnética, un agente conductor y un aglutinante, y la porosidad del electrodo magnético rico en litio está en un rango de 10% a 60%. De acuerdo con la divulgación, se aplica un campo magnético en un proceso de preparación de electrodos a través de un método de extracción de litio asistido por campo magnético, que puede mejorar la porosidad y la velocidad de conducción de iones de litio del electrodo, lo que mejora de este modo la velocidad de transferencia de masa interna del electrodo y, obviamente, mejora la eficacia de extracción electroquímica de litio.
