Synthesis of ZnO/polypyrrole composites and an application in Zn/Ni rechargeable batteries

ZnO/polypyrrole (PPy) composites with different morphology synthesized by a facile ultrasound- assisted chemical polymerization method were used as anode material in order to improve the cycle performance of Zn/Ni rechargeable battery. Granular and layered ZnO/PPy composites were prepared. They provided capacity stability superior to conventional ZnO electrodes during the cycle test.
