“…Besides, the cyclability of the VNQDs@PCNFs-N/F electrode is superior to most previously reported vanadium-based and nitrides anodes in sodium storage (Figure h, Table S1). ,− ,,− In association with the previous conversion mechanism in which transition metal nitrides could electrochemically react with sodium and generate corresponding metal nanoparticles embedded in sodium superionic conductors–Na 3 N matrix, the reason for the capacity increase during the cycles is summarized. In addition to abundantly exposed active sites, the incorporation of a highly conductive Na 3 N and carbon nanocages structure could also markedly satisfy the fast diffusion of ion/electrons through the electrode even at high current densities, ultimately leading to a capacity improvement during cycling processes.…”

The kinetics incompatibility between battery-type anode and capacitive-type cathode for sodium ion hybrid capacitors (SIHCs) seriously hinders their overall performance output. Herein, we construct a SIHCs device by coupling with quantum grade vanadium nitride (VN) nanodots anchored in one-dimensional N/F co-doped carbon nanofiber cages hybrids (VNQDs@PCNFs-N/F) as the freestanding anode and the corresponding activated N/F co-doped carbon nanofiber cages (APCNFs-N/F) as cathode. The strong coupling of VN quantum dots with N/F co-doped 1D conductive carbon cages effectively facilitates the ion/electron transport and intercalation–conversion–deintercalation reactions, ensuring fast sodium storage to surmount aforesaid kinetics incompatibility. Additionally, density functional theory calculations cogently manifest that the abundant active sites in the VNQDs@PCNFs-N/F configuration boost the Na+ adsorption/reaction activity well which will promote both “intrinsic” and “extrinsic” pseudocapacitance and further improve anode kinetics. Consequently, the assembled SIHCs device can achieve high energy densities of 157.1 and 95.0 Wh kg–1 at power densities of 198.8 and 9100.5 W kg–1, respectively, with an ultralong cycling life over 8000 cycles. This work further verified the feasibility of kinetics-compatible electrode design strategy toward metal ion hybrid capacitors.

“…The structure collapsing during the repeated Zn 2+ intercalation and deintercalation processes and the dissolution of vanadium oxide are likely to blame for the poor cycling performance. 63 In contrast, the VO 2 (B)@Ta 4 C 3 exhibits a capacity retention of 92.0% (322.2 mA h•g −1 ) after 100 cycles at the current density of 0.2 A•g −1 (Figure 5f), suggesting the addition of Ta 4 C 3 can effectively improve the cycling performance. Figure 5g,h shows the charge/discharge curves of VO 2 (B)@Ta 4 C 3 at 0.5 and 1 A• g −1 , respectively.…”

A two-dimensional MXene (Ta4C3) was innovatively used herein to modulate the space group and electronic properties of vanadium oxides, and the MXene/metal–organic framework (MOF) derivative VO2(B)@Ta4C3 with 3D network cross-linking was prepared, which was then employed as a cathode to improve the performance of aqueous zinc ion batteries (ZIBs). A novel method combining HCl/LiF and hydrothermal treatments was used to etch Ta4AlC3 to obtain a large amount of accordion-like Ta4C3, and the V-MOF was then hydrothermally grown on the surface of the stripped Ta4C3 MXene. During the annealing process of V-MOF@Ta4C3, the addition of Ta4C3 MXene liberates the V-MOF from agglomerative stacking, allowing it to show additional active sites. More significantly, Ta4C3 prevents the V-MOF in the composite structure from converting into V2O5 of space group Pmmn but into VO2(B) of space group C2/m after annealing. A considerable advantage of VO2(B) for Zn2+ intercalation is provided by the negligible structural transformation during the intercalation process and the special tunnel transport channels, which have an enormous area (0.82 nm2 along the b axis). According to first-principles calculations, there is a strong interfacial interaction between VO2(B) and Ta4C3, which deliver remarkable electrochemical activity and kinetic performances for the storage of Zn2+. Therefore, the ZIBs prepared with the VO2(B)@Ta4C3 cathode material exhibit an ultra-high capacity of 437 mA h·g–1 at 0.1 A·g–1 while showing good cycle performance and dynamic performance. This study will offer a fresh approach and a reference for creating metal oxide/MXene composite structures.

“…These observations support the electrons transfer from conductive MXene to VOPO 4 ·H 2 O, [ 27 ] meaning a strong coupling between VOPO 4 ·H 2 O and MXene interfaces, which is directly confirmed by the appearance of TiOV in the O 1s HR‐XPS spectrum of VOPO 4 ·H 2 O@MXene in comparison with that of bare VOPO 4 ·2H 2 O (Figure 4f). [ 28 ] Additionally, the P 2p HR‐XPS spectrum is given in Figure S18 (Supporting Information). In order to explore the reason behind the excellent water stability of VOPO 4 ·H 2 O@MXene, DFT calculation was carried out to compare the VO water bond length of oxygen deficient and perfect VOPO 4 ∙H 2 O, which is the quantitative index of the interaction between water molecules and VOPO 4 .…”

storage system, which would propel the substantial development of the energy storage technology. [4] In order to design high energy density storage devices, the identifying of host materials with high performance, especially elevated work potential, is essential. Due to the high electronegativity of oxygen, the metal oxides own strong ionic chemical bonds, which consequently result in increased plateau voltages. [5] Examples of such oxides owning potential high discharge voltages are amorphous V 2 O 5 (≈0.9 V), [6] MoO 2 (1.9 V), [7] TiO 2 (≈1.0 V) [8] and so on. Despite their advantage in working potential, they usually suffer from low capacity, discontented cycling life, and inferior rate capability, which originate from the slow reaction kinetics caused by the strong Coulombic interaction between the trivalent Al 3+ and oxide host lattice. [9] Previous researches have demonstrated that water molecules can be applied as "lubricant" to facilitate ions diffusion. [10] Typically, vanadyl phosphate dihydrate (VOPO 4 •2H 2 O) with a long intercalation chemistry history, has been recently developed as a potential cathode material for various alkali metalion batteries, meriting from its high redox reaction potential due to the strong inductive effect of [PO 4 ] tetrahedrons and the large interlayer space stemming from the interlayer water molecules. [11] Moreover, the easier multivalent ions (Mg 2+ and Zn 2+ ) intercalation into VOPO 4 •2H 2 O can take place with the aid of the water molecules. [11e,12] The study of vanadyl phosphate hydrate as AIBs cathode was first reported in 2020 by Wang and co-workers via fabricating a VOPO 4 -graphene heterostructure. [11f ] Although an improved cycling performance originating from its zero-strain property is achieved, the potential high discharge plateau voltage and capacity of vanadyl phosphate hydrate are underutilized. In addition, the effect and mechanism of the bonded water molecule content and its stability on the aluminum storage behavior have not been systematically studied.In this work, we select VOPO 4 •2H 2 O as a model cathode to reveal its Al 3+ storage behaviors. As expected, the VOPO 4 •2H 2 O presents high discharge plateau and holds high potential Al 3+ storage capacity. We further investigate the relationship between water content and electrochemical performance. Interestingly, our density functional theory (DFT) calculations results reveal that, compared with VOPO 4 •2H 2 O and VOPO 4 , the VOPO 4 •H 2 O possesses the lowest Al 3+ diffusion barrier and Al ion batteries (AIBs) are attracting considerable attention owing to high volumetric capacity, low cost, and high safety. However, the strong electrostatic interaction between Al 3+ and host lattice leads to discontented cycling life and inferior rate capability. Herein, a new strategy of employing water molecules contained VOPO 4 •H 2 O to boost Al 3+ migration via the charge shielding effect of water is reported. It is revealed that VOPO 4 •H 2 O with water lubrication effect and smaller steric hindrance ...
