Electrochemical Characteristics of SnO2 and SiO2 Nanotubes Prepared by Template Synthesis

摘要

Pervious studies have pointed out that oxides,such as Sn-based and Si- based materials,have higher Li-ion storage capacities than carbonaceous materials currently employed.To obtain the high-performance anode materials of Li-ion batteries,the nanostruc-tured electrode process was developed for preparing SnO2 and SiO2 nanotubes,by using sol- gel/template method.Porous polycarbonate (PC) membranes were used as template with a nominal pore diameter of 100V400 nm.
