Recent development of rechargeable solid-state metal-air batteries for electric mobility

Abstract

The demand for clean energy from renewable sources is widely acknowledged as a solution to energy security and global warming, but its intermittent nature poses challenges to sustainable power supply. On the other hand, electrochemical storage of energy is a sustainable and reasonably priced method for storing and distributing clean energy to overcome the current global energy crisis and environmental deterioration. They are a viable solution for incessant future power supply due to their high efficiency, safety, and affordability. According to current research, rechargeable aqueous metal-air batteries offer theoretically high energy density, but they suffer from difficulties such as reactivity with aqueous electrolytes, poor performance in practice, and dendrite formation. Solid-state metal-air batteries, on the other hand, provide superior energy density and safety but confront problems in the metal-electrolyte interface and catalyst design. As a result, this research examines the most recent advances in rechargeable solid-state metal-air batteries for electric mobility. This review also provides a theoretical foundation for rational design and performance optimization of innovative electrolytes for RSSBs, highlighting the importance of these electrolytes, electrode reactions, their applications, and future innovation prospects in the development of next-generation energy storage systems.
