“…The intercalated difluoro(oxalato)borate (DFOB − ) anion holds a high diffusion coefficient and low energy loss, and the optimal ratio of propylene carbonate (PC) and EMC solvent offers a high ionic conductivity. 96 Such a combination achieved an high discharge capacity of 134 mAh g −1 and a stable cyclability (retaining 88% capacity after 500 cycles). Herein, it is of great significance to develop novel anions with high conductivity and low diffusion barrier under an excellent solvent environment.…”

For a dual-ion battery (DIB) configuration, both anions and cations contribute to the capacity. A high anion intercalation operating potential corresponds to a wide working window, which leads to both high energy density and power density for DIBs. Because orderly layered structures and proper interlayer space can accommodate anion intercalation, graphite was widely used as the cathode for DIBs. However, the relatively low discharge capacity and poor cycling stability of graphite cathode limit the practical application of DIBs. Therefore, it is crucial for anion storage to construct a robust and stable cathode. On the basis of the delicate structural design of electrodes, we summarize the main factors affecting the anion storage and the strategies for improving performance of DIBs, which will provide far-reaching significance for improving the capacity and stability of DIBs.

Only until recently, Sun et al reported the intercalation reversibility for DFOBanions into molybdenum disulfide (MoS 2 ), and the Li-MoS 2 half-cell shows a discharge capacity of 118 mAh g -1 at the current density of 0.5 mA cm -2 and voltage range of 3.0-5.0 V.

Dual‐ion batteries (DIBs) utilize the working mechanism, that is, anions and cations participate in electrochemical reactions on the cathode and anode materials to achieve energy storage simultaneously. The high potential of anions de‐/intercalation endows DIBs with high energy density. However, the relatively low specific capacity and poor interface stability limit the further development of DIBs. Therefore, improving the performance of cathode materials has become the key to promoting the practical application of DIBs. In this review, a variety of DIBs cathode materials are classified in detail and their energy storage mechanism and typical characteristics are comprehensively summarized. Finally, the rules and corresponding strategies which should be followed in the design of high energy cathode materials are proposed, and the potential development direction of DIBs in the future is summarized.
