Surface states of solids provide a unique way to graft organic molecules into monolayers by simple dip chemistry. Such interfaces can be highly functional and serve as a foundation for the formation of precisely controlled nanostructures of other materials via atomic/molecular diffusion, adsorption, and growth. The coverage, orientation, consistency, and functionality of these monolayers can be easily tailored to create technologically important materials. On the other hand, research on batteries has skyrocketed in recent times due to a paradigm shift toward nonconventional energy resources and the pledge of the transport sector to go soon all electric. Therefore, meeting energy demands by coping with global climate protocols is important for sustainable development. In this regard, the fabrication of efficient, stable, and long-lasting electrodes for lithium as well as nonlithium batteries is needed. However, they suffer from several electrode issues which ultimately limit their storage capacity and cycle life. Recently, there has been a scientific trend to incorporate suitably chosen organic monolayers for controlled syntheses of active materials that are highly catalytic and functional to improve the performances of metal–air and other batteries. Moreover, molecular surface modification techniques have been commercially adopted for corrosion inhibition, moletronics, surface activation/protection, etc. Looking at the resurgence of molecular engineering and unconventional energy storage systems in recent times, it is necessary to bring molecular dynamics and versatility in designing novel electrode materials. This review intends to increase the attention to address the challenges of battery electrodes using cutting-edge surface chemistry and molecular engineering techniques by providing critical insights on molecular monolayers for the development of futuristic metal–air batteries.
