Pristine carbon nitride as active material for high-performance metal-free supercapacitors: simple, easy and cheap.

ABSTRACT: Understanding the basic properties of pristine carbon nitride electrodes is of great importance for their further applications as supercapacitor materials. To this end, a comparative study of unmodified carbon nitride is crucial to understand the difference between the bare material and its composite counterparts described in the literature. Therefore, the aim of this paper is to explore the electrochemical behaviour of casting-produced C₃N₄ electrodes using cyclic voltammetry, charge/discharge curves and impedance spectroscopy. The results from this study show a capacitance value of 113.7 F g^-1 at 0.2 A g^-1 with an impressive retention of 89.2% after 5000 charge and discharge cycles at 3.0 A g^-1. In addition, this material shows a lar
