The objective in this study was to design the architecture of highly mesoporous ZMO hollow microspheres (ZMO) with the double-shelled structure as an anode material for lithium ion batteries at different calcination conditions. The ZMO are prepared via the following processes: the synthesis of hydrophilic glucose-based carbon sphere as a template by hydrothermal process, the formation of the carbon spheres@NiMo-glycolates via polyol reaction of EG by solvothermal process, along with subsequent calcination conditions to synthesize the double-shelled ZMO hollow microspheres. ZMO microspheres with calcination temperatures were differently synthesized via the combined mechanism of both inward and outward Ostwald ripening, which consist of their outer shell, inner shell, void space between outer shell and inner one, and inner hollow core. The improved rate capability for NCO-500 calcined at 500 oC was easily identified with the exceptionally high specific capacity, which was maintained at 1130 mAh/g without fading. |
