Abstract

We present the in situ oxidative synthesis and electrochemistry of novel pseudo-capacitive nanostructured composite electrode material based on multi-walled carbon nanotube (MWCNT), manganese dioxide (MnO2) and polyaniline (PANI), namely, MWCNTCOOH/MnO2/PANI (PCNAM) for high performance supercapacitor applications. The composite shows about six-fold improvement of electrochemical response compared to MWCNT. The maximum specific capacitance, energy density, and power density of \PCNAM\ were 517.13
