The influence of the hydrothermal conditions used for preparing precursors was studied with respect to
the properties of the resulting KOH-activated carbons (KOH-ACs). The influence of the hydrothermal
temperature (180 vs. 240 C) was only minor on the textural properties of the KOH-ACs. However, the
hydrothermal conditions did affect the electrical conductivity of the KOH-ACs. A higher conductivity was
observed for the ACs prepared from precursors at the higher temperature and shorter reaction time. This
study highlights an overlooked relationship in-between the degree of condensation in the precursors
prepared from hydrothermal carbonization and the electrical conductivity of the corresponding ACs
