June 27, 2014



By a News Reporter-Staff News Editor at Science Letter -- Current study results on Science have been published. According to news reporting from Hefei, People's Republic of China, by NewsRx journalists, research stated, "Urchin-like Sn-ZnO-C composite have been successfully prepared by thermal annealing of ZnSn(OH)(6) precursor in acetylene/argon gas (1/9; v/v). The phase of the urchin-like Sn-ZnO-C has been characterized by X-ray diffraction (XRD) and Raman spectrum."

The news correspondents obtained a quote from the research from the China University of Science and Technology, "The images of scanning electron microscopy (SEM) and transmission electron microscope (TEM) demonstrate that the Sn-ZnO-C composite with an average of 3 mu m in diameter is composed of many core-shell nanowires and carbon nanotubes emanated from the center. The thermal annealing temperature and time have crucial effects on the formation of urchin-like structure and carbon content of the Sn-ZnO-C composites. As an anode for lithium-ion batteries, the urchin-like Sn-ZnO-C composite delivers a discharge capacity of 1,034.5 mAh/g in initial cycle and 571.9 mAh/g reversible discharge capacity after 25 cycles at a current density of 50 mA/g."

According to the news reporters, the research concluded: "The superior energy storage properties highlight the urchin-like Sn-ZnO-C composite as a potential alternative anode material in lithium-ion batteries."
