Aqueous and Non-aqueous Electrolytes for Zn-ion Batteries

Abstract

As a new type of secondary battery, the Zn-ion battery has become one of the most promising candidates for the new generation of energy storage batteries because of its high safety, low toxicity, low cost, and high potential electrolyte diversity. Acting as an important component of the Zn-ion battery, the electrolyte plays an important role in regulating the performance. Chapter 5 introduces the characteristics of and research progress on Zn-ion electrolytes from the perspective of aqueous and non-aqueous systems. The distinguishing features and working mechanisms of different electrolytes are discussed. The aqueous electrolytes are comprehensively discussed as they are the most mainstream and flexible electrolytes, with the most diverse application prospects. At the end of the chapter, a general perspective for the next generation of Zn-ion batteries with high performance and long cycling life is presented.
