An electric-field assisted PECVD method was developed to grow strictly vertical graphene arrays (SVGAs) as electrode materials of ECs. The EC-SVGAs with aqueous or organic electrolyte exhibit excellent C_A of 1.72 mF cm⁻², Φ of 80.6°, and energy density of 0.33 μWh cm⁻² at 120 Hz with arbitrary AC filtering performances, which is far better than most carbon-related devices, demonstrating the potential for replacement of conventional AECs.
