| Abstract | With continued dependence on carbon-based fuels and rising concerns of environmental issues, the development of rechargeable metal–air batteries has recently gained tremendous attention. However, due to the slow kinetics of electrochemical oxygen reactions, the charge and discharge processes of a rechargeable metal–air battery must be catalyzed by using bi-functional catalysts that are active towards both the oxygen reduction and oxygen evolution reactions. This review focuses on recent developments in bi-functional catalysts and their catalytic activity in relation to materials composition, morphology, and crystal structure obtained through various synthetic techniques. The discussion is divided into sections based on the main types of recent bi-functional catalysts such as transition metal- and carbon-based materials, and hybrids which consist of the two. The subsections are then divided based on the metal substituents, types of dopant, degree of doping, and defect densities, discussing the effects of composition. In parallel, morphological effects on the catalytic activity, such as unique nanostructured design, surface area enhancements, and porosity, are also discussed. Currently, bi-functional oxygen electrocatalyst research is heading in the direction of reducing the loading of precious metals, and developing cost-competitive non-precious metal- and carbon-based catalysts to enable commercialization of rechargeable metal–air batteries for various applications including electric-drive vehicles and smart-grid energy storage. To understand the origin of bi-functional catalytic activity, future catalyst research should be conducted in combination with in situ characterizations, and computational studies, which will allow exploitation of active sites to maximize the efficacy of bi-functional catalysts. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
