Abstract

Highlights: The current status of aluminum-air batteries is discussed. Battery components- anode, cathode, electrolyte, design & assembly are evaluated. Design & assembly of Al–air batteries are the key factors in the performance and viability. Abstract: Aluminum–air (Al–air) batteries, both primary and secondary, are promising candidates for their use as electric batteries to power electric and electronic devices, utility and commercial vehicles and other usages at a relatively lower cost. This paper provides an analysis of the performance of these batteries with a component by component comparison with other technologies. It also aims to identify the major impediments that must be overcome for the battery. Al alloys are inexpensive and provide better electrochemical performances as compared to pure Al. The oxygen reduction reaction (ORR) at the cathode is traditionally controlled by platinum and other noble catalysts, but several carbonaceous materials, transitional metal oxides, and polymer-based systems may be satisfactory alternatives. The aqueous alkali electrolytes, though widely used at present, may be suitably replaced by non-aqueous electrolytes, aprotic and ionic liquids for both primary and secondary batteries. The different types of design and assembly for greater performance and economic viability are also described. This review may serve as a scientific tool for the progression of research on Al–air battery system.
