Energy storage devices such as electrochemical capacitors, fuel cells, and batteries efficiently transform chemical energy into electrical energy. Batteries convert chemical energy into electrical energy by means of a redox reaction between the anode and cathode.

2. Non-faradaic capacitive storage. The capacitance of a conventional capacitor typically ranges between 10 −6 –10 −2 F, therefore the energy stored in the capacitor is too small for meaningful practical uses. For example, for a 50 mF capacitor with an applied voltage of 100 V, the energy stored is only 250 J.
The properties of capacitive electrode materials govern the energy storage performance of supercapacitors. Extensive research efforts have been devoted to developing novel capacitive materials. These efforts have focused on two main strategies: 1) increasing the ion-accessible surface area of capacitive materials and 2) incorporating redox-active
