Nitrogen/oxygen co-doped monolithic carbon electrodes derived from melamine foam for high-performance supercapacitors
A novel monolithic carbon sponge is prepared by a ZnCl 2 -assisted carbonization of commercial melamine foam (MF) at 800 °C in a N 2 atmosphere. The as-prepared nitrogen/oxygen co-doped carbon sponges (NOCSs) can be directly applied as monolithic electrodes for supercapacitors without using any addi...

-assisted carbonization of commercial melamine foam (MF) at 800 °C in a N

atmosphere. The as-prepared nitrogen/oxygen co-doped carbon sponges (NOCSs) can be directly applied as monolithic electrodes for supercapacitors without using any additives. It is found that ZnCl

activation plays an important role in improving the supercapacitive behavior of NOCSs. Compared with the NOCS without ZnCl

activation treatment, the optimal NOCS-1/10, obtained with a ZnCl

/MF weight ratio of 1 : 10, has the best capacitive performance due to its unique porous architecture, rich pseudocapacitance-active species, and good electron/ion transfer feature. It exhibits a high specific capacitance (242 F g

at a current density of 0.5 A g

and 325 F g

at a scan rate of 10 mV s

) and good electrochemical cyclability (97% after 10 000 cycles at 5.0 A g

). When being further assembled into an all-solid-state supercapacitor (PVA/KOH electrolyte), it can deliver an energy density of 4.33 W h kg

at a power density of 250 W kg
