The
growing
demand
for
efficient
energy
storage
systems,
particularly
in
portable
electronics
and
electric
vehicles,
has
led
to
increased
interest
supercapacitors,
which
offer
high
power
density,
rapid
charge/discharge
rates,
long
cycle
life.
However,
improving
their
density
without
compromising
performance
remains
a
challenge.
In
this
study,
we
developed
novel
3D-printed

properties.
rGO
were
fabricated
using
direct
ink

(DIW),
allowed
precise
control
over
thickness,
ranging
from
4
24
layers.
A
unique
formulation
was
optimized
the
printing
process,
consisting
of
rGO,
cellulose
acetate
(CA)
as
binder,
acetone

PANI
coating
applied
via

polymerization
(COP)
up
five
deposition
cycles.
Electrochemical
testing,
including
cyclic
voltammetry
(CV),
galvanostatic
(GCD),
impedance
spectroscopy
(EIS),
revealed
that
