In short, anion batteries are a class of batteries that have great development prospects in addition to cation batteries. The research of anion storage is not only applied to the development of various anion batteries, but also can be extended to DIBs based on various anions and cations.
Conclusion and outlook Anion batteries are one of the most promising and alternative storage technologies. Compared with LIBs , anion batteries exhibit higher theoretical capacity and energy density, as shown in Fig. 12 a. However, practical capacity and energy density of anion batteries display obvious difference.
However, the effect of the anion on the properties of batteries is still unclear. Herein, lithium bis (trifluoromethylsulfonyl)imide (LiTFSI) and lithium difluoro (oxalato)borate (LiDFOB) are selected to investigate the working mechanism of anions in solid and liquid systems.
As promising alternatives to lithium-ion batteries, rechargeable anion-shuttle batteries (ASBs) with anions as charge carriers stand out because of their low cost, long cyclic lifetime, and/or high energy density.
According to the previous literatures, we know that researchers have summarized the progress and challenges of certain anion storage, such as fluoride-ion batteries (FIB) , chloride ion battery (CIB) , and DIBs . However, an overall review of various anion storage batteries has not been reported.
Lithium salts exert a great influence on the electrochemical performance of lithium metal batteries. Dissociated Li-ions present rapid transfer dynamics through solvation with a solvent in liquid batteries or complexation–decomplexation with a polymer in solid batteries.
