Organic Nitro Compounds for Batteries

High-performance energy storage technologies, with the representatives of rechargeable and redox flow batteries, are required due to the flying development of electrical gadgets and the increase in demand for sustainable energy supply. Nevertheless, most of these batteries are made of inorganic active materials with several critical deficiencies, preventing their further development. Organic nitro compounds (ONCs) are an appealing alternative in this context, providing the advantages of multi-electron redox processes and adjustable battery performance by structural modification. In this review, the utilization of ONCs as the electrode materials of batteries, interfacial layer materials for metal batteries, as well as redox shuttle additives is explored. The authors also go over material design issues, together with the corresponding electrochemical reaction mechanisms, and an overview of related viewpoints and future research directions to facilitate the advancement of this field is provided.
