For exploring promising energy storage devices beyond lithium ion batteries, aluminum ion batteries (AIBs) are desirable cells with high energy-to-price ratios because of abundant natural resources, the higher energy density of aluminum and elimination of unexpected safety risks. Nevertheless, an ideal rechargeable AIB configuration with ultrahigh capacity is still fundamentally pursued. For fundamentally promoting the most promising chalcogen or chalcogenide-based AIB positive electrode materials, here rechargeable tellurium (Te) nanowire positive electrodes are demonstrated to construct novel tellurium–aluminum batteries. The cell configuration allows Te nanowires for delivering an ultrahigh discharge capacity ∼1026 mA h g−1 (with a specific current of 0.5 A g−1) along with an initial 1.4 V discharge voltage, competitive with the record-setting energy density of the documented AIBs. For essentially tackling the dramatic capacity loss in tellurium positive electrodes, the mechanism of impacting the rechargeable ability is linked to the production of soluble tellurium chloroaluminate compounds upon both chemical dissolution and electrochemical conversion processes. As a consequence, the cell configuration is proved to substantially suppress the unexpected shuttle effects induced by soluble tellurium chloroaluminate compounds via employing reduced graphene oxide to support the tellurium positive electrodes as well as utilizing functionalized carbon nanotube membranes to modify the separators. The implication of the results suggests a nice plateau for massively promoting the rechargeable ability of AIBs, advancing remarkable routes for achieving ultrahigh capacity and energy density.

Conventional solid-to-solid conversion-type cathodes in batteries suffer from poor diffusion/reaction kinetics, large volume changes and aggressive structural degradation, particularly for rechargeable aluminium batteries (RABs). Here we report a class of high-capacity redox couples featuring a solution-to-solid conversion chemistry with well-manipulated solubility as cathodes—uniquely allowed by using molten salt electrolytes—that enable fast-charging and long-lived RABs. As a proof-of-concept, we demonstrate a highly reversible redox couple—the highly soluble InCl and the sparingly soluble InCl 3 —that exhibits a high capacity of about 327 mAh g −1 with negligible cell overpotential of only 35 mV at 1 C rate and 150 °C. The cells show almost no capacity fade over 500 cycles at a 20 C charging rate and can sustain 100 mAh g −1 at 50 C. The fast oxidation kinetics of the solution phase upon initiating the charge enables the cell with ultrafast charging capability, whereas the structure self-healing via re-forming the solution phase at the end of discharge endows the long-term cycling stability. This solution-to-solid mechanism will unlock more multivalent battery cathodes that are attractive in cost but plagued by poor reaction kinetics and short cycle life.

Heterostructures facilitate the generation of the interfacial electric field (IEF) that enhances charge transfer and ion diffusion, resulting in improved electrochemical performance in rechargeable aluminum batteries (RABs). However, the ability of heterostructures to generate the IEF is limited, and research efforts on IEF modulation remain scarce, particularly in the field of RABs. Herein, sulfur (S) vacancies are introduced into the core–shell MoS 2 /ZnS heterostructure (Vs-MoS 2 /ZnS) to strengthen the IEF and enhance aluminum storage performance. First-principles computational analyses demonstrate S vacancies increase the work function difference, induce spontaneous interfacial charge transfer, and enhance the IEF. The increased IEF accelerates electron transport, reduces ion diffusion barriers, and increases the adsorption capacity of charge carriers, significantly improving the reaction kinetics of RABs. Moreover, the designed core–shell structure, together with S vacancies, provides strong structural integrity and numerous active sites to the host material. Benefiting from these merits, the Vs-MoS 2 /ZnS cathode demonstrates enhanced reversible capacity (220 mAh g −1 at 0.5 A g −1 ) and long-term cycling stability (127 mAh g −1 over 2000 cycles at 4.0 A g −1 ). This work provides an effective approach for designing heterostructures by modulating the IEF, offering novel insights into the development of advanced RABs cathodes.

Herein, a self-charging mechanism of rechargeable aluminum (Al) batteries with Chevrel phase molybdenum sulfide (Mo 6 S 8 ) cathode is reported. The results unambiguously reveal that the self-charging is a spontaneous disproportionation of Al intercalated Mo 6 S 8 originated from the dynamic shift of Al between occupied sites during Al intercalating and resting. The theoretical study indicates that the fully Al intercalated Mo 6 S 8 in the format of Al 4/3 Mo 6 S 8 is kinetically accessible driven by electrochemical overpotential but thermodynamically unstable due to the repulsion between Al 3+ cations. This mechanism is a true self-charging with no input of any form of energy, thus distinctly superior to the previously reported self-charging mechanisms. Based on this discovery, a semi-flow Al Mo 6 S 8 battery is designed and demonstrated with long-lasting discharge capability and high capacity.

Rechargeable aluminum batteries (RABs) are promising alternatives to lithium-ion batteries in large-scale energy storage applications owing to the abundance of their raw materials and high safety. However, achieving high energy density and long cycling life simultaneously holds great challenges for RABs, especially for high capacity transition metal selenide (TMS)-based positive materials suffering from structural collapse and dissolution in acidic ionic liquid electrolyte. Herein, Se-doped carbon encapsulated Cu 2 Se with yolk-shell structure (YS/Se-C@Cu 2 Se) is rationally constructed to address such issues. Electrochemical and spectroscopic analyses as well as density functional theory calculations show that the highly conductive Se–C shell enhances the electrochemical reaction kinetics of the electrode and provides strong adsorption for the soluble Cu and Se species. Benefiting from these merits, the optimal YS/Se-C@Cu 2 Se cathode manifests a high specific capacity of 1024.2 mAh/g at 0.2 A/g, a superior rate capability of 240.5 mAh/g at 3.2 A/g, and a long-term cycling stability over 2500 cycles. This work offers a feasible approach to the design and construction of low-cost and efficient TMS-based positive materials for realizing practically usable RABs.

Compared with the widely developed positive electrodes, the research on the high stability negative electrodes is far from in-depth in nonaqueous Al batteries. In order to fundamentally solve these key problems, including Al dendrites, corrosion and pulverization, it is urgent to develop an alternative stable negative electrode. Herein, the corrosion-resistant, low-voltage-hysteresis and stable Zn is demonstrated as a promising negative electrode. Since the deposited Al particles on the Zn electrode are prior to Zn in the stripping reaction, Zn electrode can remain good structural integrality, thus presenting great cycling stability and corrosion resistance. Importantly, the results in Al-Zn symmetric cells indicate that Zn possesses the ultra-low voltage hysteresis (∼17 mV at 0.5 mA cm −2 ), superior cycling stability (800 cycles at 1.0 mA cm −2 ) and Al plating/stripping reversibility characteristics. Additionally, the Zn-graphite full battery based on Zn as negative electrode and flake graphite as positive electrode delivers stable discharge capacity of 81.1 mAh g −1 over 300 cycles. The results in this work open an effective approach for constructing corrosion-resistant, low-voltage-hysteresis and stable negative electrode, further indicating that Zn is great promising as negative electrode for Al dual-ion batteries.

Nonaqueous rechargeable Al batteries (RABs) have attracted significant research interest due to the extremely abundant reserves, high theoretical capacities, and low-cost. However, the commonly used nonaqueous RAB ionic liquid (IL) electrolytes are highly air-sensitive and high-cost, which seriously limits their commercial application. Herein, AlCl3–guanidine hydrochloride (AlCl3–GdnHCl), a new low-cost and environmentally friendly deep eutectic solvent (DES) with only 1/40 of the cost of [EMIm]AlxCly is introduced into applications for nonaqueous RABs. The battery displays a discharge capacity of 128 mAh g–1 at 0.1 A g–1, which is significantly higher than that of 88 mAh g–1 in [EMIC]AlxCly electrolyte. It can reach 124.6 mAh g–1 at 1 A g–1 with the Coulombic efficiency of 99.5% for 1000 cycles. According to the mechanism studies, during the charge–discharge cycle, the fast deposition/dissolution reaction of Al took place at the anode side, while intercalation/deintercalation reaction of [AlCl2(Gdn)n]+ ions and chloroaluminate anions [AlxCly]− (i.e., Al2Cl7– and AlCl4–) occurred at the graphite cathode side. With such significant electrochemical behaviors, the AlCl3–GdnHCl DES possesses great potential for use in high-performance storage devices.

Transition metal selenides (TMSs) become one of the most promising cathode materials for rechargeable aluminum batteries (RABs) due to the advantages of high specific capacity, low cost, and simple preparation process. However, TMSs are soluble in the acidic chloroaluminate ionic liquid electrolyte during cycling, leading to undesirable electrochemical performance. Herein, rechargeable Al-Cu 2 Se batteries are fabricated with acetylene black modified separator (AB/GF/A) showing excellent electrochemical performance with capacity retention of 95 mAh g −1 after 5000 cycles at 0.5 A g −1 and 166.1 mAh g −1 at 1.0 A g −1 . By combining electrochemical tests and ex situ spectroscopy and electronic microscope characterizations, it is revealed that the dissolved Cu and Se species adsorbed on the surface of AB/GF/A still remain electroactivity, which transforms the diffusion-controlled mechanism of Cu 2 Se to surface pseudocapacitance-controlled behavior, thus suppressing the shuttle effects and boosting the reaction kinetics. The in-depth understanding of the functionalized separator in energy storage mechanism of TMSs could provide reference for further progress of RABs in the future work.

Aluminum batteries (ABs) have recently become a type of battery technology that has attracted much attention due to their advantages such as abundant resources and high theoretical capacity. However, the development of ABs is limited by the inherent characteristics of the positive electrode materials, so finding high-performance positive electrode materials has become a top priority in research. Transition metal sulfides/selenides, as positive electrode materials for ABs, offer notable benefits such as high specific capacity and long cycle life, showing great application potential. In this study, a nanoscale porous dodecahedral NiS2/NiSe2 heterojunction was designed and prepared for an ABs positive electrode. The unique heterojunction structure generates a built-in electric field, which facilitates the transport of electrons and ions and improves the reaction kinetics. Nanoparticles can provide a larger specific surface area, while the porous structure supports buffering volume expansion and promotes electrolyte infiltration, thereby improving the electrochemical performance. Experimental results show that the NiS2/NiSe2 heterojunction exhibits a notable initial capacity of 375.5 mAh/g within the voltage range of 0.01–2.3 V, and it can still maintain 81.1 mAh/g after 400 cycles. This research provides ideas for developing a high-performance positive electrode for ABs.

Metal aluminum batteries (MABs) are considered potential large-scale energy storage devices because of their high energy density, resource abundance, low cost, safety, and environmental friendliness. Given their high electrical conductivity, high theoretical specific capacity, and high discharge potential, Te is considered a potential positive electrode material for MABs. Nonetheless, the critical issues induced by the chemical and electrochemical dissolution of tellurium and subsequent chemical precipitation on bare Al negative electrodes result in poor cycle stability and low discharge capacity of Al—Te batteries. Here an efficient TiB 2 -based modified layer has been proposed to address bare Al electrodes (Al/TB). Consequently, the low-voltage hysteresis and long cycle life of the Al/TB negative electrode have been achieved. In addition, the electrochemical performance of the Al—Te battery based on the Al/TB negative electrode is dramatically improved. Furthermore, the modified separator technology is introduced to match with the as-designed Al/TB negative electrode. Therefore, the record-setting long-term cycle stability of up to 500 cycles has been achieved in the Al—Te battery. The facile strategy also opens a potential route for other high-energy density battery systems, such as Al—S and Al—Se batteries.

Aluminum batteries (ABs) are a promising alternative to lithium-ion batteries (LIBs) in the future. The development of aluminum batteries (ABs) is closely related to their cathode material. In this paper, we successfully designed and prepared a nanorod structure Sb 2 Se 3 @PPy as cathode material for ABs. It exhibits a high reversible capacity of 302 mAh/g at 0.2 A/g, and the capacity is maintained at about 210 mAh/g after 50 cycles. In addition, the electrochemical reaction mechanism and kinetic process of Sb 2 Se 3 @PPy were studied. The results showed that the PPy coating layer reduced the volume change of Sb 2 Se 3 , prevented irreversible deformation, enhanced the structural stability and electronic conductivity.

Aluminum batteries have received extensive research because of the safety, abundance and high capacity of Al anode. Most previous works are concentrated on improving the specific capacity of the cathodes, while other important issues such as cheap cathode-electrolyte system and high areal active material loading have often been overlooked. This paper reports that cheap graphite paper (GP) coupled with low price AlCl 3 /Et 3 NHCl ionic liquid (IL) electrolyte can form a practical Al dual-ion battery (ADIB). By adjusting the AlCl 3 content in IL, the energy storage of GP with high-loading is improved. The ADIB exhibits 71 mAh g −1 at 200 mA g −1 with a loading of 15.16 mg cm −2 , which is almost unattenuated over 1400 cycles. The GP cathode presents 47 mAh g −1 at 150 mA g −1 when the loading increased to 30.21 mg cm −2 . Even at an ultrahigh loading of 46.35 mg cm −2 , the cathode can still achieve 75 mAh g −1 (3.5 mAh cm −2 ) at 40 mA g −1 for over 500 stable cycles. The high capacity is contributed by a self-activating process of AlCl 4 − intercalation, which is closer to the diffusion-controlled battery behavior. The GPs simultaneously exhibit high areal capacity, energy/power density and long-life cycling performance which demonstrates their wide commercial prospects.
