Electrolytes for K-, Ca-, Mg-, and Al-ion Batteries

Abstract

Alternative batteries to lithium- and sodium-ion batteries are also very important, and have received a lot of attention, i.e., K-ion batteries; Ca-ion batteries; Mg-ion batteries; Al-ion batteries. Electrolytes are also important for their development. In Chapter 4, we summarize the development of non-aqueous electrolytes for these metal-ion batteries over recent years, compare the advantages and disadvantages of different non-aqueous electrolytes, briefly explain the working principles of these batteries, and analyze the current problems of non-aqueous electrolytes for these batteries. It is hoped that this discussion will play a role in promoting the development of non-aqueous electrolytes for these alternative metal-ion batteries.
