a Schematic of fabrication processes of a single ACPEC unit (I); and the integrated filtering capacitors consist of different ACPEC units connected in series (II). b, c TEM images of the positive CPN film electrode material and d, e negative p-CNT film electrode material under different magnifications, respectively. The white dotted circles in (e) indicate pore defects over the CNT walls of p-CNT film.
