Abstract
Given the advantages of being abundant in resources, environmental benign and highly safe, rechargeable zinc-ion batteries (ZIBs) enter the global spotlight for their potential utilization in large-scale energy storage. Despite their preliminary success, zinc-ion storage that is able to deliver capacity > 400 mAh g−1 remains a great challenge. Here, we demonstrate the viability of NH4V4O10 (NVO) as high-capacity cathode that breaks through the bottleneck of ZIBs in limited capacity. The first-principles calculations reveal that layered NVO is a good host to provide fast Zn2+ ions diffusion channel along its [010] direction in the interlayer space. On the other hand, to further enhance Zn2+ ion intercalation kinetics and long-term cycling stability, a three-dimensional (3D) flower-like architecture that is self-assembled by NVO nanobelts (3D-NVO) is rationally designed and fabricated through a microwave-assisted hydrothermal method. As a result, such 3D-NVO cathode possesses high capacity (485 mAh g−1) and superior long-term cycling performance (3000 times) at 10 A g−1 (~ 50 s to full discharge/charge). Additionally, based on the excellent 3D-NVO cathode, a quasi-solid-state ZIB with capacity of 378 mAh g−1 is developed.

1 Introduction
Battery technologies are the key to delivering significant advances in a wide range of industries, from portable electronics and electric vehicles to renewable power [1,2,3,4,5]. Given the looming concerns over the availability and safety hazards of lithium resources, rechargeable zinc-ion batteries (ZIBs) are relatively abundant in resources and environmental benign as compared to alkaline metals. To add in the easy manufacturing process, good safety characteristics and mature recycling process, ZIBs are the cost-effective solution for stationary applications in the long run as well [6,7,8,9]. Nevertheless, for most ZIBs, their specific capacity, cycling stability and rate capability are limited by cathode materials [10,11,12,13]. Developing cathode materials with outstanding electrochemical performance is imperative but yet remains a major challenge to be overcome.
The exploration focus of ZIB cathode materials remains on manganese-based oxides, such as α-MnO2 [14, 15], β-MnO2 [16], γ-MnO2 [17], α-Mn2O3 [18], Mn3O4 [19], and ZnMn2O4 [20, 21], which can deliver initial charge/discharge capacities up to 200–350 mAh g−1 under low rates. Nevertheless, their capacities decay drastically owing to the Mn dissolution via the disproportionation reaction upon repeated electrochemical cycling. Recent advances in reversible Zn2+ ion (de)intercalation in VO2 [22, 23], V2O5 [24,25,26], V2O5·nH2O [27, 28], Zn0.25V2O5·nH2O [29], H11Al2V6O23.2 [30], Ca0.25V2O5·nH2O [31], LiV3O8 [32], Na0.33V2O5 [33], Na2V6O16·3H2O [34], Mn0.15V2O5·nH2O [35], K2V8O21 [36], and VS2 [37] have motivated further exploration into vanadium-based cathodes for ZIBs. For example, a freestanding paper cathode of layered calcium vanadium oxide bronze demonstrates 340 mAh g−1 at a low current density [31] and layered Na2V6O16·3H2O as the host for Zn2+ ion conveys ~ 300 mAh g−1 (current rate: 180 mA g−1) and a high-rate performance [e.g., operating at 14.4 A g−1 (128 mAh g−1)] [34]. Despite current achievements, their reversible capacity is still far from being satisfactory (< 400 mAh g−1) owing to tardive Zn2+ diffusion.
The rich chemistry of ammonium vanadate (NH4V4O10, NVO) arising from the double layers of V4O10 and vanadium in high oxidation state makes it a great potential candidate for accommodating Zn2+ ions. In addition, the pillaring effect of NH4+ ions enlarges the interlayer spacing or “gallery” space (Fig. S1) [38], which promote Zn2+ ion diffusion along the tunnel (i.e., favorable electrochemical capacity and electrode kinetics). The successful reversible storage of Li+ (\(r_{{{\text{Li}}^{ + } }}\) = 0.74 Å) [39,40,41], divalent Mg2+ (\(r_{{{\text{Mg}}^{2 + } }}\) = 0.72 Å) [42], as well as larger-sized Na+ (\(r_{{{\text{Na}}^{ + } }}\) = 1.02 Å) [43, 44], and Ca2+ (\(r_{{{\text{Ca}}^{2 + } }}\) = 1.00 Å) [45] in NH4V4O10 as verified by theoretical calculations and experimental electrochemical measurements further predicts the feasibility of taking up Zn2+ cations with similar size (\(r_{{{\text{Zn}}^{2 + } }}\) = 0.76 Å).
To prove the above prediction, we firstly performed the first-principles calculations to evaluate the Zn2+ ion intercalation behaviors in monoclinic NVO. Similar to the accommodation of Na+ ions [46], the intercalated Zn2+ ions energetically prefer the rest gallery space and sites. Using bulk Zn as the reference state, the binding energy was calculated to be − 3.18 eV, which is much stronger than that in layered V2O5 (− 2.06 eV) [47]. Figure S1 illustrates three possible migration paths: diffusion between two VO layers (i.e., along [010] and [100] directions) and that through VO layer (i.e., [001] direction). It is found that the migration of a Zn2+ ion directly along [100] direction seems impossible because the path is blocked by the NH4+ ions. Although the NH4+ ion that resides in the lattice spacing may be skirted between two NH4+ ions via diffusion, intercalation of Zn2+ ion at this site is extremely unstable as the initially placed Zn2+ ion would relax spontaneously to a nearby gallery site. Therefore, this possibility could be safely ruled out. The migration energy barrier, which reflects Zn2+ ion diffusivity, is determined by the maximum energy along each diffusion path. Figure 1 shows the calculated results of Zn2+ diffusion along [010] direction and through a VO layer in monoclinic NVO. Notably, lower energy barrier (0.63 eV) is demonstrated when Zn2+ ion diffuses along the [010] direction. In contrast, diffusion of a Zn2+ ion through a VO layer is also hindered as steric effect imposes a significantly large energy barrier (2.89 eV) for ion migration [48]. These results clearly suggest the feasibility of monoclinic NVO in providing fast Zn2+ ion intercalation along the [010] direction within the interlayer region.
The electrochemical performance of ZIBs, especially at high charging/discharging rates, is mainly determined by the Zn2+ ion solid-state diffusion process (i.e., rate-determining step) in the electrode materials. Thus, it is highly desirable to minimize the dimensions of NVO active materials in order to accelerate the Zn2+ ion kinetics. Thus, we attempt to synthesize one-dimensional (1D) NVO nanobelts to achieve this goal. Meanwhile, to avoid the agglomeration of NVO nanobelts, NVO nanobelts are designed to self-assemble into three-dimensional (3D) flower-like architecture (abbreviated as 3D-NVO, Fig. 2a), which can maintain structural integrity during repeated Zn2+ (de)intercalation. Although there are some reports on the fabrication of 1D NVO [43, 49, 50], engineering them into 3D-NVO presents a great challenge but might bring a significance to the development of electrode materials for ZIBs and quasi-solid-state ZIBs.
2 Experimental
2.1 Synthesis of 3D-NVO
In a typical synthesis, 2 mmol ammonium metavanadate (NH4VO3) and 2 mmol oxalic acid (H2C2O4) were added into deionized (DI) water (30 mL) under magnetic stirring, creating a kelly green solution. Then, it was put into an autoclave (50 mL) and placed in a microwave oven heated under 180 °C for 30 min. Afterward, the product was washed with DI water and ethanol and then frozen under liquid nitrogen to subject a vacuum drying process for about 48 h.
2.2 Calculation Methods
Vienna Ab-Initio Simulation Package was adopted to conduct first-principles calculations. The spin-polarized Perdew–Burke–Ernzerhof generalized gradient approximation was used for the exchange–correlation functional [51,52,53]. Van der Waals correction was included using the Grimme scheme (D2) for simulations of monoclinic NVO (space group: C2/m) [54]. The lattice parameters of NVO were calculated to be a = 11.79 Å, b = 3.68 Å, c = 9.93 Å and β = 99.49°, consistent well with experimental values. A (1 × 2 × 2) supercell involving 152 atoms (N8H32V32O80) was constructed to simulate diffusion behavior of zinc ions in NVO. It was relaxed with force convergence criteria of 0.01 eV Å−1. Moreover, 500 eV cutoff energy and Γ-centered 3 × 5 × 2 k-mesh were used. The climbing image nudged elastic band method was adopted to achieve the pathway with the minimum energy for Zn ion diffusion [55]. Because of the strong electronic correlations in the localized d orbitals of V ions, an effective parameter of U–J = 4.0 eV was applied for an on-site Coulomb interaction, which was believed to be able to provide more appropriate description of electronic properties in vanadium oxides [56].
2.3 Materials Characterization
The X-ray diffraction (XRD) patterns were acquired from an advanced X-ray diffractometer with Cu Kα radiation (Bruker D8). A field-emission scanning electron microscopy (SEM) system (Hitachi, Model SU8220) was used to investigate the morphology of the products. To further determine their microstructures, transmission electron microscopy (TEM) characterization (FEI, Model Talos F200S) operating at 200 kV was carried out. The X-ray photoelectron spectroscopy (XPS) was measured on ESCALAB 250Xi (Thermo Fisher).
2.4 Electrochemical Measurements
The electrochemical performance of the 3D-NVO materials was tested by assembling them into coin-type cells in air. Typically, 80 wt% 3D-NVO was mixed with 10 wt% carbon nanotubes and 10 wt% poly(vinylidenefluoride) (PVDF) in the solvent of N-methylpyrrolidone (NMP). The as-formed slurry was then pasted onto the titanium foils (diameter: 1 μm) to achieve the cathode part, which was later coupled with zinc foils anode and 1 M Zn(ClO4)2 in propylene carbonate (PC) as the electrolyte, for complete coin-cell configuration. In addition, quasi-solid-state ZIBs were assembled using the as-prepared 3D-NVO cathode, zinc foil anode, and the electrolyte of solid polymer membranes. The solid membranes were prepared as follows: (1) 0.264 g Zn(ClO4)2 and 0.75 g PVDF were initially dissolved in 10 mL N, N-dimethylformamide (DMF) under magnetic stirring, (2) adding 1 mL of zinc bis(trifluoromethanesulfonyl)imide (Zn(TFSI)2, 1 M) in 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI), and (3) the mixed solution was poured into the mold and dried at vacuum oven for 8 h under 80 °C. The tests were carried out on a Neware battery system, and the discharging/charging profiles were performed within 0.3–1.5 V (vs. Zn2+/Zn). Cyclic voltammetry was performed with a IVIUM electrochemical workstation.
3 Results and Discussion
In this paper, 3D-NVO cathode materials were successfully synthesized by reacting ammonium metavanadate (NH4VO3) with oxalic acid (H2C2O4) in aqueous solution through a one-pot microwave-assisted hydrothermal method. Figure 2b shows the XRD pattern of 3D-NVO sample. All the diffraction peaks are readily assigned to a pure monoclinic structure of NH4V4O10 (JCPDS Card No. 31-0075), agreeing well with the literature [49, 57]. The intensity of (001) peak is extremely high, which illustrates the preferential exposure of (001) surface facets. Its elemental composition and chemical states were further identified by X-ray photoelectron spectroscopy (XPS). V, N, and O elements are presented, and two peaks at approximately 401.2 and 530.2 eV are the characteristic binding energies of N and O, respectively (Fig. S2). Meanwhile, high-resolution XPS spectrum of V 2p in Fig. 2c is split into the overlapped V5+ (2p3/2: 517.4 eV) and V4+ (2p3/2: 516.4 eV) peaks, displaying the average vanadium oxidation state of + 4.74, proving the sectional reduction of pentavalent vanadium by oxalic acid [58].
SEM and TEM were employed to examine the morphology and microstructure of the as-prepared 3D-NVO. The low-magnification SEM image in Fig. 2d reveals the uniform 3D microflower-like morphology of the 3D-NVO, and each of them shows a diameter in the range of 4–10 μm. Magnified SEM image (Fig. 2e) and TEM examination (Figs. 2f and S3) indicate that hierarchical microflowers are constructed by numerous NVO nanobelts with a length of 2–5 μm and a width of 100–200 nm. Moreover, a lateral-lying nanobelt found in Fig. 2f displays the side view of the nanobelt and its thickness is estimated to be around 20 nm. The high-resolution TEM (HRTEM) observation further demonstrates that the interplanar spacing of the layered NVO along c-axis direction is as large as 0.93 nm (inset of Fig. 2f). The selected-area electron diffraction (SAED) pattern of an individual NVO nanobelt (Fig. 2g) unveils single-crystalline character by showing well-defined diffraction spots (zone axis: [001]). HRTEM image glimpsed from the middle of a nanobelt (Fig. 2h, upper panel) exhibits two sets of lattices with d-spacings of 0.184 and 0.193 nm, matching well with the (020) and (− 205) planes of monoclinic NVO, respectively. In addition, from the HRTEM observation on the edge of a nanobelt (Fig. 2h, bottom panel), we can see the lattice fringes (d-spacing of 0.184 nm for (020) planes) perpendicular to the length of the nanobelt, illustrating the preferential orientation growth along the [010] direction. Furthermore, Fig. 2i depicts the scanning TEM (STEM) and the corresponding elemental mapping of a NVO nanobelt, indicating uniform distribution of V, N, and O elements.
The in situ self-assembly of NVO nanobelts into 3D microflowers is driven by microwave irradiation heating (MIH), which is a very fast (30 min). To announce the importance of MIH, conventional autoclave hydrothermal reactions (C-HT) at different times were carried out, while other experimental parameters are kept the same as those of MIH. It was found that, as shown in Fig. S4, only NVO nanobelts without 3D assemblies could be produced in C-HT even after prolonged reaction time of 2, 6, and 12 h (almost no sample was presented after 30 min of reaction). Furthermore, under the method of C-HT, NVO nanobelt morphology was also widely observed in the literature using similar reactants, reaction temperatures, and time [41, 42, 46, 49, 50]. Hence, the role of MIH appears to be critical for a successful growth of the 3D-NVO, which can directly interact with reactants by producing more homogeneous heat distribution at molecular level throughout the entire solution as compared to C-HT (Fig. S5), hence reducing reaction time and enhancing reaction kinetics [59].
Electrochemical performance of the 3D-NVO cathode was evaluated in coin-type cells. Figure 3a shows its voltage-capacity profiles at a low rate of 100 mA g−1 for the first three cycles. Zn2+ intercalation (discharge) and deintercalation (charge) are represented by the S-shaped sloping curves, which correspond to solid solution processes. After the first discharge, a capacity of 607 mAh g−1 is achieved, and followed by a charge capacity of 487 mAh g−1, denoting a Coulombic efficiency (CE) of 80%. As shown in Fig. 3b, the capacity illustrates an outstanding cycling performance with almost no capacity fading during the subsequent cycles, and the CE is close to 100% from the 2nd cycle onward. Remarkably, the sustained reversible capacity (485 mAh g−1, i.e., uptake/release of 3.5 Zn per unit formula of NVO) is extraordinarily high, which has not yet been achieved for the reported ZIB cathodes (Table S1). Good high-rate performance is essential to build fast-charging ZIBs. As demonstrated in Fig. 3c, the cell was run between 0.1 and 10 A g−1. Capacities of 486, 475, 453, 411, 343, and 246 mAh g−1 are displayed at current densities of 0.1, 0.2, 0.5, 1.0, 2.0, and 5.0 A g−1, respectively, and the sloping discharge/charge profiles are also well retained at various rates (Fig. S6). Moreover, a capacity of 142 mAh g−1 is still delivered even at 10 A g−1 (approximately 50 s to full discharge/charge). Particularly, even after rapid charging/discharging, the 3D-NVO can still recover to high capacity of 478 mAh g−1 when the rate is returned to 0.1 A g−1. Furthermore, the stability of this cathode at 10 A g−1 is superior, showing almost no capacity loss after 3000 cycles (Fig. 3d) and unchanged discharge/charge profiles (Fig. S7). In contrast, the cathode of NVO nanobelts obtained from the traditional hydrothermal method (Fig. S4c, d) demonstrates a fast capacity decaying (only 58% capacity retention after 300 cycles) at 10 A g−1 (Fig. S8), confirming the superiority of the 3D-NVO cathode.
The 3D-NVO is placed in a Ragone plot (energy density vs. power density) based on working potential, specific capacity, and current density for performance evaluation. Encouragingly, as displayed in Fig. 3e, our 3D-NVO exhibits a very high energy density of 321 Wh kg−1 at a specific power of 69 W kg−1. Furthermore, an outstanding power density of 6.9 kW kg−1 (corresponding energy density: 90 Wh kg−1) can also be obtained. These results pass significantly beyond most advanced ZIB cathodes such as VS2 [37], V2O5 [25], LiV3O8 [32], Na0.33V2O5 [60], Zn2V2O7 [61], Na3V2O7(OH)2·2H2O [62], and Na2V6O16·1.63H2O [63], evidencing the superior ZIBs performance of our 3D-NVO materials.
To understand the electrochemical Zn2+ ion storage kinetics of 3D-NVO cathode, cyclic voltammetry (CV) was performed under scan rates of 0.1–1.0 mV s−1 (Fig. 3f). The redox peaks are gradually broadened and slightly shifted with increasing scan rate, but the CV contour is maintained. Their current (i), in principle, is obedient to a power-law relationship with the scan rate (ν) via the equation: i = aνb. When the b value is 0.5, it represents a diffusion-controlled process, whereas b = 1.0 stands for a capacitive process. Accordingly, the data in Fig. S9 reveal a combination of Zn2+ ion intercalation and capacitive reactions in the 3D-NVO cathode. (b values range from 0.78 to 0.86 for the marked cathodic and anodic peaks in Fig. 3f.) Again, based on the equation of i(V) = k1ν (capacitive effect) + k2ν1/2 (diffusion effect), their proportion in the total stored charge can be quantified (e.g., the orange area in Fig. 3g corresponds to the capacitive contribution). Figure 3h illustrates the contributions from the two different charge storage mechanisms, and we find that the capacitive contribution increases from 40.8 to 68.4% with an increasing scan rate (0.1–1.0 mV s−1), which is primary factor that enables fast reaction kinetics and superior high-rate performance.
To investigate the storage mechanism of Zn2+ ion in the 3D-NVO cathode, ex situ XRD experiments at different charge–discharge states were performed to examine its structural evolution (Fig. 4a). Clearly, there is no significant change in the XRD patterns under various states of discharge/charge and the characteristic peaks of NH4V4O10 located at around 9.0° (001), 25.5° (110), 27.7° (111), 34.0° (− 311), and 44.6° (− 205) are retained without detecting any new diffraction peaks, which is indicative of the well-preserved lamellar structure. In addition, with a careful observation, it is found that the (001) peak is slightly shift toward lower angles during the discharge process, confirming the Zn2+ ion intercalation reaction mechanism with an expansion of the NH4V4O10 interlayer spacing. When Zn2+ ions are completely released, this peak can be recovered, demonstrating the reversible behavior of the NH4V4O10 lattice layer. The varying of vanadium chemical states upon Zn2+ ion (de)intercalation was further evaluated by ex situ XPS analysis (Fig. 4b). At the end of the 1st discharge state, the V 2p peaks can be fitted to V3+ (2p3/2: 515.5 eV) specie, which is consistent with the fully discharged product (Zn3.5NH4V4O10) derived from the galvanic curve. (485 mAh g−1 corresponds to an uptake of 3.5 Zn2+ ion per formula unit.) Upon subsequent charging process, the V 2p spectrum almost fully recovers to its pristine state (V4.74+) in Fig. 2c. The XPS V 2p spectra under the 2nd cycle further evidence the reversible transition between V4.74+ and V3+ via the reaction of NH4V4O10 + 3.5Zn2+ + 7.0e− ↔ Zn3.5NH4V4O10. Furthermore, SEM images of the cycled 3D-NVO cathode reveal that the pristine 3D microflower-like structure is well maintained (Fig. 4c), and the surface of NVO nanobelt is very smooth without experiencing severe pulverization (Fig. 4d). The HRTEM image with clear lattice fringes and the spotted SAED pattern suggests its highly crystalline nature is preserved (Fig. 4e). The scanning TEM (STEM) image and the corresponding elemental mapping illustrate a homogeneous distribution of V, O, N, and Zn in the full discharged NVO nanobelt (Fig. 4f). Additionally, the crystal structure of NH4V4O10 is still retained after 100 cycles at 10 A g−1 (Fig. S10). On the basis of these ex situ XRD, XPS, SEM, and TEM results, we believe that the crystal structure and microstructure of our 3D-NVO cathode are highly stable and reversible upon Zn2+ ion intercalation/deintercalation, confirming superior electrochemical performance.
Solid-state (quasi-solid-state) batteries with high safety are appealing great attention for energy storage applications [64,65,66,67]. Hence, we assembled a quasi-solid-state ZIB based on 3D-NVO cathode, zinc anode, and the electrolyte and separator of poly(vinylidenefluoride)-Zn(ClO4)2-based polymer membrane (Fig. 5a). Figure 5b shows the charge–discharge curves at 100 mA g−1. Obviously, the profiles are the same as those of liquid ZIB in Fig. 3a, sharing the above-mentioned Zn2+ (de)intercalation mechanism. During the first cycle, specific capacities of 320 (discharge) and 315 mAh g−1 (charge) are achieved with a CE of 98%. Remarkably, in the following cycles, the specific capacity is slightly increased (corresponding to the activation process) and stabilized at 378 mAh g−1 with CE of about 100% after 50 cycles (Fig. 5c), which is much higher than state-of-the-art quasi-solid-state ZIBs (e.g., ~ 200 mAh g−1 for zinc orthovanadate array//Zn array [68], and ~ 300 mAh g−1 for V5O12·6H2O nanobelts//Zn foil [69], etc.), making it promising for solid-state energy storage systems.
4 Conclusions
In summary, 3D-NVO cathode was created with high capacity for ZIBs. Firstly, the first-principles calculations were carried out to confirm feasibility of Zn2+ intercalation into monoclinic NVO, in which the intercalates tend to accommodate in the interlayer region of NVO along the [010] direction. Subsequently, to enhance the Zn2+ ion diffusion kinetics and maintain the structural integrity of the electrode during long-term cycling process, a 3D flower-like architecture assembled by NVO nanobelts was designed and fabricated using a microwave-assisted hydrothermal method. In ZIB application, this 3D-NVO cathode can bring a large reversible capacity of 485 mAh g−1 (corresponds to energy density of 321 Wh kg−1) under current density of 0.1 A g−1. Additionally, superior long-term (3000 times) high-rate cycling performance is demonstrated (i.e., power density: 6.9 kW kg−1). Postmortem investigation of cycled 3D-NVO further identifies that 3.5 Zn2+ ion is taken up upon intercalation through the following reaction: NH4V4O10 ↔ Zn3.5NH4V4O10 without affecting the crystallinity and microstructure of the pristine 3D-NVO. Finally, a high-capacity (378 mAh g−1) quasi-solid-state ZIB composed of the 3D-NVO cathode is developed.
