The physical and chemical properties of the cathode catalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), raman spectra, electric catalytic properties, single battery power performance and so on. The results showed that after adding PVDF pore-forming catalytic performance is best, the peak current density of 137.33mA·cm-2, its resistance also decreased significantly, when preparation into a single battery also has the highest power density of the four methods, 22.89 mW·cm-2. 查看全文查看/发表评论下载PDF阅读器 相关附件：附件1版权转让声明书附件1 -->
