Pseudocapacitive Storage in Advanced Nanostructured Materials towards Flexible Supercapacitor Device - Bhanu Ranjan - Bog

Flexible Supercapacitors (FSCs) possessing higher power output, greater energy density, extended cycle life, superior rate performance, and eco-friendly attributes can satisfy the future energy storage and delivery requirements in upcoming flexible electronics. However, the current supercapacitors (SCs) technology based on carbonaceous or conducting polymers is constrained primarily by their low energy density, restraining their large-scale implementation. In this context, Pseudocapacitive materials such as Transition metal nitrides (TMNs) and transition metal oxides (TMOs) that undergo rapid and highly reversible redox and intercalation kinetics at or near the electrode surface, coupled with electric double-layer capacitive (EDLC) kinetics, can assist FSCs in achieving higher energy and power densities simultaneously.
