"It is important to control this process carefully as too many
defects can deteriorate the electrical conductivity, which is
the reason for the use of CNTs in the first place. Good
conductivity helps in efficient charge transport and increases
the power density of these devices," Bandaru added. "At the very
outset, it is interesting that CNTs, which are nominally
considered perfect, could be useful with so many incorporated
defects," he added. The researchers think that the energy
density and power density obtained through their work could be
practically higher than existing capacitor configurations which
suffer from problems associated with poor reliability, cost, and
poor electrical characteristics. Bandaru and Hoefer hope that
their research could have major implications in the area of
energy storage, a pertinent topic of today. "We hope that our
research will spark future interest in utilizing CNTs as
electrodes in charge storage devices with greater energy and
power densities," Hoefer said. While more re
