Abstract
Polypyrrole (PPy) encapsulated 3D flower-like NiO was prepared to investigate the role of PPy coating for high-performance electrodes. NiO@PPy showed a better electrochemical performance than pure NiO, and a "trade-off effect" between electrical conductivity and ion diffusion resistance was observed with different PPy coating thickness.
摘要
制备了聚吡咯（PPy）包覆的三维花状NiO，以研究PPy涂层对高性能电极的作用。NiO@PPy表现出比纯NiO更好的电化学性能，并且观察到不同PPy涂层厚度下电导率和离子扩散电阻之间存在“权衡效应”。
