“…Recently, as one new type of battery, dual-ion batteries (DIBs) have aroused tremendous interest in view of their low-cost, good safety, environmental friendliness and high working voltage [16][17][18][19][20][21][22][23]. Different from the conventional rocking-chair based LIBs, both cations (Li + , Na + , K + , etc.)…”

“…On the other hand, because of the deficiency of suitable cathode materials for MIBs with both high working voltages and fast Mg 2+ diffusion kinetics, utilization of anion-intercalation type cathode materials could be an effective strategy to overcome the issue. , Graphite is a typical anion-intercalation type cathode for dual-ion batteries (DIBs), and has been widely investigated previously. − As the potential of anion intercalation in a graphite cathode can be over 4.5 V versus Li + /Li, − it is expected to exhibit high working voltage in MIBs as well (estimated to be ∼3.8 V vs Mg 2+ /Mg). Moreover, the anion intercalation in the graphite cathodes also demonstrates fast kinetics, − contributing to the rate performance of the Mg-DIB.…”

Magnesium-ion batteries (MIBs) have received increasing attention for next-generation energy storage recently because of the natural abundance, high capacity, and dendrite-free deposition of Mg. However, their applications are hindered by irreversible Mg anode plating in conventional electrolytes and the lack of cathode materials, demonstrating high working voltage, satisfactory Mg 2+ diffusivity, and long cycling life. In this work, we first developed a novel magnesium-ion based dual-ion battery (Mg-DIB) by utilizing expanded graphite as the cathode and Ti-doped niobium pentoxide nanoflakes (Ti−Nb 2 O 5 NFs) as the anode. The Ti−Nb 2 O 5 NFs showed hierarchical structures of microspheres with diameters of 4−5 μm assembled by nanoflakes. For the first time, the Mg-ion storage mechanism in Ti−Nb 2 O 5 NFs was investigated. Benefiting from the hierarchical structure design and pseudocapacitive intercalation behavior of Mg ions, the Ti−Nb 2 O 5 NF anode exhibited fast Mg-ion diffusion. Consequently, the Mg-DIB exhibited a high discharge capacity of 93 mA h g −1 at 1 C (1 C corresponding to 100 mA g −1 ), along with good long-term cycling performance with a capacity retention of 79% at 3 C after 500 cycles. The Mg-DIB also demonstrated a capacity retention of 77% at 5C, indicating its good rate performance. Moreover, the Mg-DIB exhibited a high discharge medium voltage of ∼1.83 V, thus enabling a high energy density of 174 W h kg −1 at 183 W kg −1 and 122 W h kg −1 at a high power density of 845 W kg −1 , among the best of the reported magnesium-ion full batteries. Our work provides a new strategy to improve the performance of MIBs and other rechargeable batteries.

“…To achieve an optimal match between the anode and cathode in a DIB configuration, more efforts have been made via modifications of the anode, such as designing an integrated anode or flexible interface − , preparing high-working-potential , and high-capacity − anode materials. However, the capacity and stability of DIBs are still restricted by the incompatible capacity between the anode and cathode.…”

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.
