Abstract
To obtain high-ionic-conductivity and high-electron-conductivity electrode materials, we design novel dual high-conductivity networks through importing a polymeric gel electrolyte into the electrode bulk by doping gold nanoparticles, which endows the membrane electrode with not only a high electron conductivity of 1.66 s·cm-1 but also a high ionic conductivity of 2.7 × 10-2 s·cm-1, as well as a good surface area capacitance of 1098 mF·cm-2 at 0.5 mA·cm-2. The membrane electrode shows great mechanical strength, high flexibility, and tremendous stability, and the design concept based on dual conductive networks could be also applied to other electrode systems and other energy storage fields.
