“…Figure f shows that in the first cycle, the reduction peak appears around 1.4–1.5 V, which may be related to the extraction of chloroaluminate and the conversion of Mn 4+ to Mn 2+ . The oxidation peak appears around 1.75 V, which can be attributed to the conversion of Al 2 Cl 7 – to Al and AlCl 4 – and the conversion of Mn 2+ to Mn 4+ during charging. − As shown in Figure f, the intensities of the oxidation and reduction peaks were greatly reduced in the second and third cycles, and the curves obtained in the three cycles could not overlap well, indicating that the reversibility of the battery was poor. This may be related to the selenide generated in the electrochemical reaction, which can pass through the glass fiber separator and induce a shuttle effect.…”

Transition metal selenides have shown outstanding performance as cathode materials for aluminum-ion batteries and have thus become a popular choice for cathode materials. Herein, Mn-based carbon fibers (Mn/CNFs) were first synthesized by electrospinning as a precursor, and then MnSe composites were prepared by a melt-diffusion method. However, due to polyselenides and selenides being generated during electrochemical reactions, the cycling stability of MnSe cathode materials is poor. After 200 cycles, the discharge specific capacity is only 176 mA h/ g. To suppress the shuttle effect of selenides and polyselenides, a CMK-3-modified separator was used instead of a glass fiber separator. Compared with MnSe-800, the replaced MnSe-800/ CMK-3 has a great capacity improvement; the initial discharge specific capacity is 1029.85 mA h/g, which after 3000 cycles, still remains at 297.84 mA h/g. The soft pack battery can still light up the LED normally under different degrees of folding, which proves the application of this material in wearable devices. This work provides a new way to improve the performance of transition metal selenides.

“…Furthermore, the energy densities of various oxide cathodes in nonaqueous AIBs are summarized in Figure 5h and Table S2, Supporting Information. [8,12,13,22,[25][26][27][28][29][30][31][32][33][34][35] Benefited from both elevated working voltage and high reversible capacity, the energy density of Li-VONB in this work could reach up to 177.7 Wh kg −1 (based on the weight of active materials), much higher than other reported oxide cathodes in AIBs.…”

development and manipulation of TMC cathodes with elevated plateau voltages to boost the energy densities of AIBs. More efforts should be devoted into this topic to explore novel cathodes with advantages in both specific capacity and operation voltage.The discharge voltage of intercalation type TMCs is determined by the crystal and electronic structure, elemental composition, and micro-morphology. As discussed in the previous literatures, the ionic character of the chemical bonds between transition metal cations and anions was proposed as an indicator to evaluate the electrochemical potential of cathode. [10] Following this rule, transition metal oxide, in which the highly electronegative oxygen anion would enable the chemical bonds to be more ionic, was predicted to achieve increased plateau voltage. [11] Particularly, vanadium-based oxides have shown the potentiality as high-voltage cathode materials as reported by recent studies, for which porous V 2 O 5 could deliver a relatively high working voltage of ≈0.79 V, and molybdenum-vanadium oxide exhibited a discharge plateau at ≈0.75 V. [12,13] More importantly, the tunable chemical valences of vanadium elements and facile distortion of V-O bonds in vanadium-based oxides provide the possibility to screen more suitable candidates with higher operating voltage by optimizing their crystal structures and electron distributions.Although the reported vanadium-based oxides demonstrated elevated working voltage, their reversible capacities and energy densities were unsatisfied, originating from the strong electrostatic interaction between the inserted Al 3+ and the crystal lattice, which hindered the ionic intercalation and diffusion. [14] Pre-intercalation, as an effective approach, has been successfully employed in various battery systems, especially multivalent-ion batteries, to improve the electrochemical performance of intercalation type electrode materials. [15] The guest ions could expand the interlayer space and shield the electrostatic interaction between charge carriers and the lattice, leading to an accelerated diffusion kinetics. [16,17] Besides, the pre-intercalated ions and molecules could exist as "pillar" to stabilize the framework as well as to reduce the loss of crystallinity, increasing the structural stability of active materials during cycling. [18,19] Nevertheless, the pre-intercalation strategy has not been studied in AIBs so far. It is highly desirable to acquire high-performance vanadium-based oxides for AIBs applications by the attractive pre-intercalation method.Owing to the low-cost, safety, and three-electron redox properties of aluminum, rechargeable aluminum-ion batteries (AIBs) are emerging as a promising energy storage technology. However, exploring suitable cathode material with both elevated working voltage and high reversible capacity remains a daunting challenge. Herein, under the guidance of density functional theory calculations, V 6 O 13 is proposed as a promising cathode candidate in AIBs for the first time. It is demonstrated tha...

Based on the intrinsic restrictions in current lithium-ion battery, Mg-based batteries are regarded as one of the most potential candidates because of their higher volumetric energy density and fewer Mg dendrites in the process of charge and discharge. However, the improved energy density of the Mg-based battery is expected to further promote their practical application. Compared with metal chalcogenides, the selenides have high electrical conductivity and special electron orbit mixing effect between the Se and the transition metal atoms. As a result, the conversion-type selenides are promising cathodes for Mg batteries with high-energy- density. Herein, this review focuses on the recent investigations on the metal selenides as cathode materials for Mg-based batteries. Their crystal structures, the preparation methods, and electrochemical properties/mechanism of transition metal selenides are unveiled. Finally, the issues and the future research of selenides for Mg batteries are discussed, such as advanced characterization methods and rational design strategies. These advances of selenides provide new ideas for realizing the characteristics of high-energy-density Mg-based batteries.
