摘要
Abstract
Tin oxide nano-particles was prepared by chemical precipitation method followed by hydrothermal reaction.The size of nano-tin oxide particles analyzed by TEM was about 5 nm.SnO2/C microspheres were prepared by coating nano-sized tin dioxide particles with carbon-contained species derived from condensation reaction between 2,4-hydroxy acid and formaldehyde followed by heat treatment.The influence of the addition of tin oxide particles on morphology and properties of the material were investigated.The results show that when content of nano-tin oxide is 40％,the electrochemical properties of SnO2/C composite is the best.The initial reversible capacity was 825.2 mAh/g when the current density was 100 mA/g during charging and discharging,and the capacity maintained 593.2 mAh/g after 100 cycles,which was 71.9％ of the initial reversible capacity.关键词
