Abstract
Influence of the thermocatalytical synthesis on the
formation of the porous structure and the properties of
microporous carbon wood-based materials was shown. It was
found that increase of activation temperature and addition ratio
of alkali activator can be used to control not only total pore
volume, but also micropore and mesopore proportion. The
results of tests on the synthesized carbon materials as electrodes
in supercapacitors are shown, as well as the influence of
properties of the porous structure of carbon materials on
working characteristics of electrodes. It was shown that the
increase of activation temperature from 600 °C to 800 °C led to
an increased proportion of mesopores in the porous structure;
this negatively influencen the cell capacity of the supercapacitor.
It was found that the most feasible way of production of activated
cabons for the use as electrodes in supercapacitors with sulphuric
acid-based electrolyte is low-temperature activation
