Реферат: Un material activo catodico para una batería secundaria de litio incluye un nucleo de partícula secundaria de oxido de metal de litio formado al aglomerar partículas primarias de oxido de metal de litio; y una cubierta formada al recubrir el nucleo de partícula secundaria con titanato de bario y oxido metálico. Este material, activo catodico permite realizar una batería secundaria de litio con seguridad mejorada, particularmente en características de estabilidad térmica y sobrecarga. A cathode active material for a secondary lithium battery includes a secondary particle core of lithium metal oxide formed by agglomerating primary particles of lithium metal oxide; and a shell formed by coating the secondary particle core with barium titanate and metal oxide. This cathode active material allows a secondary lithium battery to be made with improved safety, particularly in thermal stability and overload characteristics.
Composite cathode active material, cathode and lithium battery employing same, and preparation method for same
