dc.description.abstract | A simple, low-cost and environmentally friendly method has been used to obtain highly
porous biomorphic carbon monoliths with a good combination of interconnected macro-, meso- and microporosity, and good electrical conductivity and mechanical strength, making these
biocarbon materials interesting for electrochemical applications as binder-free electrodes. Highly
porous monolithic biocarbons were obtained from beech wood precursors through pyrolysis
and subsequent surface modification in a steam heated to 970°C with different activation times. The obtained biocarbons demonstrated good electrical conductivity and mechanical strength. They were studied as electrodes for supercapacitors in half cell experiments, demonstrating
maximum gravimetric capacitance of 200 F g
-1
in a basic media at scan rate 1 mV s
-1
. Galvanostatic
charge-discharge experiments showed maximum capacitance of 185 F g
-1 at current density of
0.15 A g
-1 and ~100 F g
-1 at current density of 0.75 A g
-1
. It has been shown that in addition to the
developed porous surface, the micropores with diameters exceeding 1 nm play a key role for the
enhanced electrochemical capacity. Long-cycling experiments demonstrated excellent stability
of the monolithic biocarbon electrodes with no reduction of the initial capacitance values after
600 cycles in voltammetry. | es |
