In this research, a compressible electrode of polypyrrole/carbonized melamine foam (PPy/CMF) based on commercial melamine foam and pyrrole monomer was fabricated by high temperature carbonization and in-situ polymerization. The electrochemical property of compressible PPy/CMF electrode material was investigated by three-electrode system in 1 mol/L sodium perchlorate electrolyte. The volumetric capacitance MFof compressible electrode material can achieve 3 168 mF/cm3 at 2 mA/cm3 and preserve 86.88% of initial capacitance after 1 000 charge and discharge cycles. Furthermore, cyclic voltammetry and galvanostatic charge-discharge curves of compressible electrode material did not change significantly under different compressions, indicating that PPy/CMF is an appropriate compressible electrode with high compressive stability for supercapacitor. These results demonstrate that PPy/CMF is an excellent candidate for compressible supercapacitor.
