Hollow carbon-shell/carbon-nanorod arrays for high performance Li-ion batteries and supercapacitors†
Abstract
N-doped hollow hierarchical peanut-like carbon-shells with nanorod arrays on the surface and interconnected networks in the core are prepared, which display rich porosity, superhigh specific surface area and a high degree of graphitization. The unique composition and hierarchical structure of the carbon resulted in very promising electrochemical energy storage performance.
