title: Superior electrochemical properties of Co3O4 yolk-shell powders with a filled core and multishells prepared by a one-pot spray pyrolysis.
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).
