Description
Summary:A facile and potentially scalable synthesis route to obtain SnO(2)-carbon composites was developed. SnO(2) nanoparticles were deposited on the surface of two types of graphitic carbon: (a) commercial porous graphite (HG) and (b) graphitic carbon nanostructures. The synthesis procedure consists of two simple steps: (i) room temperature formation/deposition of SnO(2) nanocrystals and (ii) thermal treatment at 350 degree C to generate SnO(2) nanoparticles (size ~3.5 nm) over the carbon surface. The electrochemical performance of the graphitic carbons and the SnO(2)-carbon composites as anode materials in Li-ion rechargeable batteries was investigated. In all cases, tape casting electrode fabrication allowed almost full active material utilization. Good cyclabilities were achieved, with HG and HG-SnO(2) showing capacities of 356 and 545 mAh g(-1), respectively after 50 cycles.
