Nitrogen-doped microporous carbons were prepared using a polyvinylidene fluoridemelamine mixture. The electrochemical performance of the nitrogen-doped microporous carbons after being subjected to different carbonization conditions was investigated. The nitrogen to carbon ratio and specificsurface area decreased with an increase in the carbon-ization temperature. However, the maximum specificcapacitance of 208 F/g was obtained at a carbonization temperature of 800°C because it produced the highest microporosity.
