Query: The modification of the pore characteristics of activated carbon, for
  use in electrical double layer capacitors, through plasma processing   It was aimed to determine whether plasma processing could contribute to
enhanced capacitance and energy density of activated carbon electrode based
electrochemical capacitors, through the formation of additional surface
charges. While an increase of up to 35% of the gravimetric capacitance, along
with ~ 20% decrease in resistance, was obtained through optimal plasma
processing, increased plasma exposure yielded a drastic reduction (/increase)
in the capacitance (/resistance). It was also found that the capacitance and
resistance modulation was a sensitive function of sample processing as well as
electrochemical testing procedure. Considering the complexity of modeling
realistic porous matrices, a metric to parameterize the reach of an electrolyte
into the matrix has been posited.
