Organic materials as charge hosts for pseudocapacitive energy storage

Abstract

Organic materials with tunable redox properties have become versatile charge storage materials due to their abundant precursors and sustainability. Environmentally benign nature and recyclability make them attractive over other classes of electrode materials. This perspective provides prospects for organic materials such as conducting polymers, two-dimensional covalent organic frameworks (2D COFs), polyaromatic hydrocarbons and their hybrids towards the design of simultaneous high charge storage with high-rate capabilities. Non-diffusional redox processes give rise to pseudocapacitance, a key parameter that overcomes the sluggish ion diffusion kinetics. The emerging area of organic materials for electrochemical energy storage is expanding beyond metal and metal-ion based rechargeable batteries. All-organic based hybrid metal-ion capacitors turn out to be the futuristic choice for sustainable energy storage. The scope for exploiting supramolecular principles towards the rational design of molecular assemblies via non-covalent interactions is discussed. Advancement of inorganic–organic hybrid architectures for the design of hybrid energy storage devices for a sustainable future is highly desired.
