Development of oxide materials for negative electrode of Li-ion battery

作为锂离子电池氧化物负极材料,锡基复合氧化物的比容量高达600mAh/g,Li4/3Ti5/3O4的循环性能优良,在某些领域,这两种负极材料有望获得商业应用。综述了近年来锂离子电池氧化物负极材料的研究进展,详细阐述了锡氧化物、锡基复合氧化物和Li4/3Ti5/3O4的嵌脱机理及性能特点。

Among the oxides that were applied to the negative materials, the specific capacity of the amorphous tinbased composite oxide was higher than 600?mAh/g, and Li4/3Ti5/3O4 had an excellent cyclic performance. It was prospective that the two negative materials could be put into commercial application in some given fields. Several negative materials of oxide for Liion battery, including tin oxide, amorphous tinbased composite oxide, Li4/3Ti5/3O4, were discussed on their charge/discharge reaction mechanisms and performance.
