Abstract
Highly crystalline Co3O4 yolk-shell powders with a filled core and various shell numbers are prepared by a simple one-pot spray pyrolysis process. Co3O4 yolk-shell powders exhibited a high initial discharge capacity of 548 mA h g(-1) and retained their capacities very well, even at a high discharge rate of 10,000 mA g(-1).
摘要
采用简单的一步喷雾热解法制备了具有实心核和不同壳数的高度结晶 Co3O4 蛋黄壳粉末。Co3O4 蛋黄壳粉末表现出高的初始放电容量 548 mA h g(-1)，并且即使在 10000 mA g(-1)的高放电率下，容量也保持得非常好。
