treatments, TAN9 exhibits an increased reversible capacity of up to ~20%
and a decreased irreversible capacity of up to ~8%. TAN11 experienced
smaller changes compared to TAN9, but displayed better cycling behaviour.
It was suggested that the acidity/basicity of the surface groups may have
an inuence on improving the electrochemical performance of hard carbon
anode materials for LIBs, but the effect of prolonged acid treatment was
insignicant.
Cho et al. have prepared crystalline nanobrillar carbon from carbon
cotton (CC), which was obtained by heating (PAN)/FeCl
