“…During the charge process (point C), the inconspicuous peak of Al 2p confirms the robbed reaction, namely, most Al 3+ ions going out. The existing Al at point C may be attributed to two possible reasons: (1) the residual Al x MoSe 2 , which cannot be oxidized during the charging process; (2) the AlCl 4 – interaction into the layers of the MoSe 2 under the electric field reported in other 2D materials. − The subsequent discharge reproduces the obvious Al peak during the second discharge process (point D), confirming the reversible motion. The high-resolution Cl 2p XPS spectra displayed an opposite trend.…”

The rechargeable aluminum-ion battery (AIB) is a promising candidate for next-generation high-performance batteries, but its cathode materials require more development to improve their capacity and cycling life. We have demonstrated the growth of MoSe 2 three-dimensional helical nanorod arrays on a polyimide substrate by the deposition of Mo helical nanorod arrays followed by a low-temperature plasma-assisted selenization process to form novel cathodes for AIBs. The binder-free 3D MoSe 2 -based AIB shows a high specific capacity of 753 mAh g −1 at a current density of 0.3 A g −1 and can maintain a high specific capacity of 138 mAh g −1 at a current density of 5 A g −1 with 10 000 cycles. Ex situ Raman, XPS, and TEM characterization results of the electrodes under different states confirm the reversible alloying conversion and intercalation hybrid mechanism during the discharge and charge cycles. All possible chemical reactions were proposed by the electrochemical curves and characterization. Further exploratory works on interdigital flexible AIBs and stretchable AIBs were demonstrated, exhibiting a steady output capacity under different bending and stretching states. This method provides a controllable strategy for selenide nanostructure-based AIBs for use in future applications of energy-storage devices in flexible and wearable electronics.

“…Thus, both anode and cathode materials must be improved for this battery system. The main eleven categories for the cathode materials are metal selenides [24,74], metal oxides [75][76][77][78][79][80], carbon [81][82][83][84], metal sulfides [85][86][87], Prussian blue [88], Mg-OMS-1 [89], polyoxometalate-(poly)pyrrole [90], MXene [91], metal phosphates [92,93] and magnesium octahedral molecular sieves [94].

We discuss the latest developments in alternative battery systems based on sodium, magnesium, zinc and aluminum. In each case, we categorize the individual metals by the overarching cathode material type, focusing on the energy storage mechanism. Specifically, sodium-ion batteries are the closest in technology and chemistry to today’s lithium-ion batteries. This lowers the technology transition barrier in the short term, but their low specific capacity creates a long-term problem. The lower reactivity of magnesium makes pure Mg metal anodes much safer than alkali ones. However, these are still reactive enough to be deactivated over time. Alloying magnesium with different metals can solve this problem. Combining this with different cathodes gives good specific capacities, but with a lower voltage (<1.3 V, compared with 3.8 V for Li-ion batteries). Zinc has the lowest theoretical specific capacity, but zinc metal anodes are so stable that they can be used without alterations. This results in comparable capacities to the other materials and can be immediately used in systems where weight is not a problem. Theoretically, aluminum is the most promising alternative, with its high specific capacity thanks to its three-electron redox reaction. However, the trade-off between stability and specific capacity is a problem. After analyzing each option separately, we compare them all via a political, economic, socio-cultural and technological (PEST) analysis. The review concludes with recommendations for future applications in the mobile and stationary power sectors.

Owing to the low-cost, dendrite-free formation, and high volumetric capacity, rechargeable Li + /Mg 2+ hybrid-ion batteries (LMIBs) have attracted great attention and are regarded as promising energy storage devices. However, due to the strong Coulombic interaction of Mg 2+ with host materials, the traditional "Daniell Type" LMIBs with only Li + intercalation usually cannot ensure a satisfactory energy density. Herein, graphene monolayers are arranged intercalating into MoS 2 interlamination to construct van der Waals heterostructures (MoS 2 /G VH). This operation transforms the construction of ion channels from pristine interlamination of two MoS 2 monolayers to the interlamination of MoS 2 monolayer with graphene monolayer, thereby greatly reducing ion diffusion energy barriers. Compared with pristine MoS 2 , the MoS 2 /G VH can obviously reduce the migration energy barriers of Li + (from 0.67 to 0.09 eV) and Mg 2+ (from 1.01 to 0.21 eV). Moreover, it is also demonstrated that MoS 2 /G VHs realize Li + /Mg 2+ co-intercalation even at a rate current of 1000 mA g −1 . As expected, the MoS 2 /G VH exhibits superior electrochemical performance with a reversible capacity of 145.8 mAh g −1 at 1000 mA g −1 after 2200 cycles, suggesting the feasibility of potential applications for high-performance energy storage devices.
