Nonbattery behavior related phase transition of electrodes is usually not favorable for any batteries because it results in performance degradation at all times. Here, we demonstrate a zinc hybrid-ion battery (ZHIB) with an unusual capacity enhancement even within 18 000 cycles by employing V2CTX MXene as the cathode, enormously differing from all reported counterparts with capacity degradation initiated within hundreds of cycles. The dominated mechanisms are determined to be MXene delamination and an unexpected phase transition during cycling. Both the original cathode and secondary derivative contribute to capacity simultaneously, resulting in the unusual capacity enhancement. Consequently, the specific capacity of 508 mAh g–1 (highest for all reported aqueous zinc-ion batteries) and high energy density of 386.2 Wh kg–1 are realized. Also, the quasi-solid-state batteries fabricated can output stably at −20 °C and in bending, twisting, stabbing, and cutting conditions. Our work brings an effective approach, that is, utilizing “unstable” electrode materials, which should usually be avoided, to achieve continuously enhanced performance of a battery. The idea to use both original and secondary materials for energy storage may be developed to be a general method to achieve extraordinary cycling stability of batteries.

Graphical High energy density : A spinel Li 4 Mn 5 O 12 cathode material with unique nano-/microspheres is prepared by using a low-temperature method. As a cathode for 2 V hybrid Mg−Li batteries, Li 4 Mn 5 O 12 exhibits a reversible specific capacity of 155 mAh g −1 and a long discharge voltage platform exceeding 2.0 V (vs. Mg/Mg 2+ ) coupled with a high energy density of 326 Wh kg −1 at a current density of 0.1 C (1 C=163 mA g −1 ). With the increasing demand for electrical energy storage, a new Mg−Li hybrid battery with Mg anode is regarded as a promising candidate because of low cost, high volumetric capacity, and dendrite-free nature of the Mg anode. Nevertheless, the characteristics of low operation voltage and low energy density for Mg−Li hybrid batteries hinders their widespread application, owing to limited reversible cathodes. To overcome these issues, a highly reversible fast Li + insertion cathode with high voltage is an effective strategy to realize high-energy-density Mg−Li hybrid batteries. Herein, we develop the 2 V high-voltage spinel Li 4 Mn 5 O 12 cathode material with unique nano-/microspheres, using a novel low-temperature method, offering a short Li-diffusion path and sufficient transport channels for electrolyte penetration into the electrode. For the first time, we demonstrate the feasibility of the spinel Li 4 Mn 5 O 12 nano-/microspheres with hierarchical architecture as a cathode for 2 V hybrid Mg−Li batteries. It exhibits a reversible specific capacity of 155 mAh g −1 and a long discharge voltage platform exceeding 2.0 V (vs. Mg / Mg 2+ ) coupled with high energy density of 326 Wh kg −1 at a current density of 0.1 C (1 C=163 mA g −1 ). Our results pave the way of constructing new hybrid Mg−Li batteries with high voltage and high energy density.

NASICON Na3V2(PO4)3 was investigated as cathode material in hybrid ion batteries using Li as counter and LiPF6 as electrolyte. The highly efficient and homogeneous heating merits of microwave irradiation facilitates the Na3V2(PO4)3 achieving excellent crystal structure, uniform carbon coating, as well as ideal particle size. After microwave irradiation, a specific capacity of 96.5 mAh g−1 is obtained for the first intercalation of lithium ion into Na3V2(PO4)3 at 0.1 C rate. For long-term cycling stability, the capacity retention reaches 84.4% at 5 C rate after 500 cycles. The unique intercalation/extraction characteristic promises Na3V2(PO4)3 an ideal candidate material for next-generation hybrid ion storage system.

Li + /Mg 2+ hybrid-ion batteries (LMIBs), integrating the merits of lithium ion batteries (LIBs) and magnesium ion batteries (MIBs) are considered as an attractive alternative of next generation metal secondary batteries. Due to the sluggish solid-state diffusion kinetic induced by the strong Coulombic interaction between Mg 2+ and host materials, pristine MoS 2 with interplanar distance of 0.62 nm exhibits inferior electrochemical performance for LMIBs with only Li + intercalation. Herein, we report an oxygen-incorporated MoS 2 (O-MoS 2 ) nanoflower anchored on graphene (O-MoS 2 /G) with the interplanar distance of O-MoS 2 from 0.62 nm expanded to 0.885 nm. Even at 1000 mA g −1 , the expanded interlayer spacing can still ensure the Mg 2+ and Li + intercalation/deintercalation into/from the host material simultaneously. Meanwhile, this configuration can effectively reduce the diffusion barrier of metal ions , increase the intercalated number of ions, and enhance the stability of structure. In addition, we found and demonstrated the intercalated Li + had a boosting effect to the intercalation kinetics of Mg 2+ . Compared with the MIBs, the migration energy barriers of Mg 2+ under the existence of Li + intercalating into MoS 2 is reduced from 0.36 eV to 0.16 eV, meanwhile the corresponding intercalation capacity and diffusion coefficient of Mg 2+ are 1.38 and 7.1 times as large as MIBs. As expect, the O-MoS 2 /G exhibits superior rate capability and cycling performance with a reversible capacity of 123.3 mAh g −1 after 2000 cycles charge–discharge processes at 1000 mA g −1 .

The nano-scale spherical Na3V2(PO4)2F3 with a NASICON structure phase was prepared with a spray drying technique, and the bagasse in Guangxi, China was selected as the carbon source to prepare Na3V2(PO4)2F3/C. The optimal preparation conditions of the composite determined using thermogravimetry, X-ray diffraction, scanning electron microscopy and electrochemical testing were: a calcination temperature of 650 °C and a 20% carbon source. The Na3V2(PO4)2F3/C has obvious redox peaks, determined by cyclic voltammetry (CV), at 3.90 V and 3.75 V, 4.32 V and 4.15 V. These two pairs of redox peaks correspond to the escape/intercalation of the two pairs of Li+/Na+. Notably, compared with pure Na3V2(PO4)2F3, the specific discharge capacity of Na3V2(PO4)2F3/C-20%, which were used as a cathode material for lithium–sodium hybrid ion batteries, increased from 55 mA h g−1 to 125 mA h g−1, which was an improvement of twofold.

The results showed that Na 2 MnPO 4 F was uniformly attached to the surface and between layers of Ti 3 C 2 -CQDs. The initial specific discharge capacity of NTC-2 at 0.1C was 67.8 mAh·g −1 , and the reversible capacity after 100 cycles was 60.7 mAh·g −1 , the capacity retention rate was as high as 90%, which all showed that Ti 3 C 2 -CQDs can enhance the cycle performance, rate performance and capacity retention rate of Na 2 MnPO 4 F. It also showed good rate performance under high current density . After the high current test, the current returned to 0.1C, and the capacity can be restored to the original value, which showed that the material has good structural stability. Therefore, Ti 3 C 2 -CQDs doped Na 2 MnPO 4 F is an important way to improve the electrochemical performance of polyanionic compounds.

Aqueous hybrid-ion batteries (AHBs) offered various advantages, including low cost, high energy density, high operation voltage, safety, and durability. These characteristics made them an attractive choice for energy storage devices. CuS was a high-capacity cathode material for Al storage. However, the rate performance of CuS under high-voltages conditions was not satisfying. Here, we prepared Co-doped CuS (Co-CuS) nanosheet material with the small band gap by using the ball milling method as the cathode material of aqueous Cu-Al hybrid-ion battery. Co doping can improve the electron transport capacity and provide more active sites. At high current density, Co doping enhances the electrochemical kinetics, operating voltage and electrochemical performance of the materials. The battery exhibits a capacity of 175 mAh g -1 at 2000 mA g -1 and 108 mAh g -1 at 4000 mA g -1 . After 200 cycles of charge and discharge tests, a capacity of 93 mAh g -1 remains. This offers a valuable approach to the development of aqueous Cu-Al hybrid-ion battery electrode materials with good electrochemical performance under high operating voltage and high current conditions.

Recently, rechargeable magnesium-ion batteries (MIBs) and rechargeable magnesium/lithium hybrid-ion batteries (MLHBs) have gained recognition as promising energy storage devices. However, the conventional CuS cathodes exhibit sluggish kinetics and poor cycle stability, thereby impeding the advancement and application of CuS. In this work, we have developed an economical and simple in-situ approach for synthesizing CuS@Cu foam (CSC) and evaluated its potential as a cathode material for both MIBs and MLHIBs. In both MIBs and MLHIBs, the CSC cathode demonstrates competitive performance. In MIBs, at a current density of 100 mA g −1 , the initial discharge specific capacity of the CSC is 150.94 mAh g −1 , which is higher than that of commercial CuS (3.99 mAh g −1 ). In MLHIBs, the CSC exhibits a discharge specific capacity of 502.95 mAh g −1 after 70 cycles at a current density of 100 mA g −1 , which significantly surpasses the discharge specific capacity of commercial CuS (229.52 mAh g −1 ). This performance improvement is attributed to the presence of Li + ions, which expedite the reaction kinetics, obviate the need for an activation process, and effectively facilitate the conversion reaction. In conclusion, by in-situ synthesis of CSC, the active material CuS firmly adheres to the Cu foam current collector. This approach is not only economical and simple but also significantly enhances the reactivity of the electrode material, thereby improving the electrochemical performance. This work provides valuable insights for the design, synthesis, and performance optimization of cathode materials of magnesium metal-based batteries.

The burgeoning demand for wearable and implantable electronic devices has spurred the necessity for the development of flexible and safe energy storage systems. Rechargeable aqueous hybrid-ion batteries (RAHBs) are considered promising alternatives, thanks to their high operating voltage, high power density, and enhanced safety. In this study, we introduce a hydrogel polymer electrolyte designed for flexible quasi-solid-state aqueous lithium-zinc (Li-Zn) hybrid ion batteries. The hydrogel polymer electrolyte (HGPE) is fabricated from a blend of agar and polyacrylamide, gelled with a 1M ZnSO 4 /2M Li 2 SO 4 aqueous electrolyte solution. The resultant hydrogel polymer electrolyte (AP-HGPE) exhibits exceptional characteristics, including outstanding ionic conductivity, a broad electrochemical stability window, and a notable ion migration number. Additionally, the Zn/AP-HGPE/Zn symmetric cells have demonstrated stable cycling for 350 h at 1 mA cm -2 , verifying the consistent deposition and stripping behavior of ions. Leveraging these properties, the full battery (Zn/AP-HGPE/LiMn 2 O 4 ) presents remarkable cycle performance, retaining 80.5 % of its initial capacity after 500 cycles at 1 C, accompanied by exemplary rate performance. Furthermore, RAHB maintains its stable electrochemical performance even under torsion and bending, highlighting its viability for integration into flexible devices. This research represents a significant stride forward in the development of RAHBs that are stable, flexible and long-lasting.

Rechargeable Mg/Li hybrid ion batteries with Mg 2+ /Li + double-salt electrolytes and safe Mg anodes are a viable option for large-scale energy storage. Nevertheless, achieving the desired reasonable electrochemical performance remains a great challenge due to the capacity limitations of conventional Li-intercalation cathodes. To mitigate this limitation, the 3D oxygenated MXene Ti 3 C 2 @CoS 2 /FeS 2 (denoted as o-Ti 3 C 2 @CoS 2 , o-Ti 3 C 2 @FeS 2 ) with both dual-storage mechanism and multidimensional structure to achieve the desirable storage capacity is engineered. Benefiting from the formation of special structure and interfacial chemical bonds Ti–O–Co/Ti–O–Fe, as well as the electronegative o-Ti 3 C 2 weaken the Co–S/Fe–S bonds, the o-Ti 3 C 2 @CoS 2 cathode exhibits superior capacity up to 425 mAh g −1 at 100 mA g −1 and overwhelming advantageous ultra-long life over 2,400 cycles at 500 mA g −1 . Simultaneously, the o-Ti 3 C 2 @FeS 2 also displays a high-rate capability, outstanding cycling stability, and fast diffusion kinetics. Furthermore, the conversion reaction of Mg 2+ /Li + co-intercalation and the charge storage mechanism during cycling are thoroughly clarified by systematic ex-situ characterizations and theoretical computations. This study reveals the influence of MXene electrode structure on the importance of electrochemical performance and provides guidance for the future design of high-performance MXene materials for energy storage applications.

The development of rechargeable Mg-based batteries with a high energy density is restricted by the high-voltage cathodes and the parasitic side reactions between the battery components and electrolytes operating at relatively high potentials. Here, we develop a hybrid Mg2+/Li+ cell using a monoclinic or orthorhombic Fe2(MoO4)3 cathode, a Mg anode, and a simple (PhMgCl)2–AlCl3 + LiCl electrolyte. Hastelloy-C alloy is proposed as a current collector of high-voltage cathode for the hybrid Mg2+/Li+ battery within a Swagelok-type cell. The application of the Hastelloy-C alloy current collector breaks the crucial bottleneck of incompatibility between the currently available current collectors and electrolytes. The hybrid cell features a low voltage polarization between the discharge and charge profiles, which is in favor of practical applications. On the other hand, because all Li+ ions are supplied by the electrolyte in a hybrid Mg2+/Li+ battery, a high Li+ concentration is required to operate at high capacities for the hybrid battery. We further show the first-hand evidence about the compensation of Li+ ions by simply soaking the cathode in the hybrid electrolyte. The prelithiation of Li+ ions into monoclinic Fe2(MoO4)3 significantly enhances the cycling stability and reversibility.

We fabricate in-situ carbon-encapsulated cuprous sulfide (Cu 2 S@C) composite through a metal-organic framework (MOF)-derived sulfurization method and compare its electrochemical performance as a displacement reaction cathode of hybrid Mg 2+ /Li + batteries with 0.4 mol L −1 (PhMgCl) 2 -AlCl 3 +1.0 mol L −1 LiCl/THF nucleophilic hybrid electrolyte and 0.2 mol L −1 Mg(HMDS) 2 -(AlCl 3 ) 2 –MgCl 2 +1.0 mol L −1 LiTFSI/DME non-nucleophilic hybrid electrolyte. Benefiting from the intrinsic property of Cu 2 S, well-defined hybrid porous structure and carbon encapsulation derived from MOFs, the Cu 2 S@C composite exhibits 399.2 mA h g −1 discharge capacity and the capacity maintains at approximately 150 mA h g −1 at 0.05 C after 50 cycles in the nucleophilic hybrid electrolyte. The mechanism investigation verifies that the formed Cu 1.96 S in the first discharge process succeeds to transform into MgS and Li 2 S, which results in the reversible displacement reaction dominantly occurring between Cu 1.96 S and Cu during subsequent cycles. When using the non-nucleophilic hybrid electrolyte, an enhanced cycling stability can be achieved due to the mitigation of ionic sulfide dissolution. The present work demonstrates the feasibility of building the structural design of low-cost displacement reaction cathode with more compatible electrolyte, and provides the potential of establishing practical hybrid Mg 2+ /Li + batteries for energy storage.
