摘要: Three-dimensional Zn3V2O7(OH)2·2H2O microspheres have been successfully synthesized by a simple and facile liquid phase precipitation method without using any surfactants or additives. The as-prepared were constructed two-dimensional nanosheets, which interconnected with each other through self-assembly. influences of the aging time, reaction temperature, pH value on morphologies products systematically investigated. Moreover, three-dimensional Zn3(VO4)2 could be formed calcination precursor. obtained further investigated as anode materials lithium-ion batteries. Electrochemical measurements showed that exhibited high discharge capacity good cycle stability, indicating potential candidates in advanced rechargeable It should noted this is first report present work will greatly expand range choices assist long-term endeavors developing for
