Abstract EN
For the first time, toxic bio-tars collected from the gasification of pine sawdust are used as the precursor for activated carbons.
Various types of activation agents including KOH, K₂CO3, H3PO4 and ZnCl₂ were screened for obtaining superior activated carbons.
When KOH was used as an activation agent, the obtained activated carbons exhibited high specific surface area and large mesopore volume.
The activated carbons were further employed to be the electrode material of supercapacitors, and its specific capacitance reached up to 260 Fg¹ at 0.25 A g¹ current density.
Also, it showed an excellent rate performance from preserving a relatively high specific capacitance of 151 Fg¹ at 50 A g¹.
The assembled device also exhibited the good electrochemical stability with the capacity retention of 90% after 5000 cycles.
Furthermore, the maximum energy density of the activated carbons in organic electrolyte reached 17.8 Wh kg-¹.
