Silver-modified hollow ZnSnO₃ boxes as high capacity anode materials for Li-ion batteries

Abstract Silver particles were dispersed on the hollow ZnSnO₃ cubes by a thermal decomposition method. With good cycling performance for lithium-ion batteries anode materials, the impacts of the Ag content on the electrochemical properties of the electrodes were compared. The results showed that the silver-modified hollow ZnSnO₃ boxes composites exhibit higher specific capacity and better cycling performance than hollow ZnSnO₃ boxes. When Ag content reaches at about 5 wt%, the retain capacity is 464.5 mAh/g after 45 cycles at a current density of 300 mA/g, which is higher than that of hollow ZnSnO₃ boxes.
