AB  - Layered VOPO4·2H2O is synthesized by the sonochemical method. An X-ray powder diffraction is used to examine the crystal structure, while scanning electron microscopy is used to reveal the morphology of the powder. The crystal structure refinement is performed in the P4/nmmZ space group. The electrochemical intercalation of several cations (Na+, Mg2+, Ca2+, and Al3+) in saturated nitrate aqueous solutions is investigated. The most notable reversible activity is found for the cycling in aluminium nitrate aqueous solution in the voltage range from −0.1 to 0.8 V vs. SCE. During the preparation of the electrode, it is observed that the structure is prone to changes that have not been recorded in the literature so far. Namely, the use of conventional binder PVDF in NMP solution deteriorates the structure and lowers the powder’s crystallinity, while the use of Nafion solution causes the rearrangement of the atoms in a new crystal form that can be described in the monoclinic P21/c space group. Consequently, these structural changes affect electrochemical performances. The observed differences in electrochemical performances are a result of structural rearrangements.

AB  - This paper reports a detailed study of crystal structure and dielectric properties of ruthenium-substituted calcium-copper titanates (CaCu3Ti4−xRuxO12, CCTRO). A series of three samples with different stoichiometry was prepared: CaCu3Ti4−xRuxO12, x = 0, 1 and 4, abbreviated as CCTO, CCT3RO and CCRO, respectively. A detailed structural analysis of CCTRO samples was done by the Rietveld refinement of XRPD data. The results show that, regardless of whether Ti4+ or Ru4+ ions are placed in B crystallographic position in AA’3B4O12 (CaCu3Ti4−xRuxO12) unit cell, the crystal structure remains cubic with Im3¯ symmetry. Slight increases in the unit cell parameters, cell volume and interatomic distances indicate that Ru4+ ions with larger ionic radii (0.62 Å) than Ti4+ (0.605 Å) are incorporated in the CaCu3Ti4−xRuxO12 crystal lattice. The structural investigations were confirmed using TEM, HRTEM and ADF/STEM analyses, including EDXS elemental mapping. The effect of Ru atoms share in CaCu3Ti4−xRuxO12 samples on their electrical properties was determined by impedance and dielectric measurements. Results of dielectric measurements indicate that one atom of ruthenium per CaCu3Ti4−xRuxO12 unit cell transforms dielectric CCTO into conductive CCT3RO while preserving cubic crystal structure. Our findings about CCTO and CCT3RO ceramics promote them as ideal tandem to overcome the problem of stress on dielectric-electrode interfaces in capacitors.

AB  - Moving toward the commercialization of safe and sustainable energy storage systems, the research on aqueous rechargeable batteries (ARBs) becomes more intensive. Moreover, development of alternative ARBs based on more abundant and sustainable element chemistry (Na, Mg, Ca, and Zn) has received significant attention. Great efforts for their development started to pay off when an aqueous sodium battery (NaTi2(PO4)3//1 M Na2SO4//Na0.44MnO2) appeared on the market alongside organic rechargeable batteries. In this study, a hybrid full- cell aqueous configuration was made from biomass-derived activated carbon (anode), 5 M aqueous solution of Ca(NO3)2 (electrolyte), and layered CaV2O6 (cathode). A high surface area carbon was synthesized by the simultaneous carbonization and activation of vine shoot- derived biochar at 700 °C under Ar atmosphere (ACvs). CaV2O6 composite with the carbon (CaVO/C) was obtained by the sol-gel complexation method. The charge storage behaviour of ACvs and CaVO/C materials was investigated in the aqueous solution of 5 M Ca(NO3)2 and showed promising results. Not only do materials individually exhibit good electrochemical behaviour, full-cell configuration ACvs700//5 M Ca(NO3)2//CaVO/C displayed improved charge storage (89 mAh g-1 at 100 mA g-1) in comparison to mentioned commercial aqueous NaTi2(PO4)3//1 M Na2SO4//Na0.44MnO2 model (≈50 mAh g-1 at ≈100 mA g-1). These results enrich the existing hybrid aqueous battery design and open up a new research era for Ca-ion batteries.

AB  - The development of safe, durable, cheap, and environmentally friendly batteries is one of the most important challenges of modern electrochemistry. Hence, there is an interest in the investigation of aqueous batteries with multivalent ions such as calcium, magnesium, or aluminium. Furthermore, the use of polyanionic compounds as cathode material can provide multi-electron transport. VOPO4·2H2O with its layered structure is a particularly interesting and promising material.
The current study is focused on the investigation of VOPO4·2H2O as cathode material in aluminium aqueous rechargeable cells. According to the literature data, the conventional reflux method is mostly used for the material’s synthesis [1]. Here is presented a sonochemical synthesis as a less time- and energy-consuming method, that starts from the mixture of vanadium(V)-oxide, phosphoric acid and water as a reaction media. The synthesis is done within 20 min.
The characterization of the synthesized material includes X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and cyclovoltammetry (CV).
XRD data were used for both the powders’ phase identification and crystal structure refinement. The structure of the powder was refined in the tetragonal space group P4/nmmZ (No. 129). Crystal structure refinement was based on the Rietveld full profile method [2]. The structure is characterized by infinite layers of PO4 tetrahedra linked to VO6 octahedra by shared oxygen atoms that form 2D sheets in the ab-planes; water molecules are located in the interlayer space. The refined cell parameters, a = b = 6.2136 Å, c = 7.4141 Å, are in good agreement with the literature data. Lattice parameter c is a measure of the interlayer distance, thus varies with water content. The value of the refined c parameter implies that the structure consists two water molecules per formula unit.
The working electrode is prepared from a slurry of sonochemically derived VOPO4·2H2O as an active material, carbon black, and a binder dispersed in a solvent. Two different binders are used: polyvinylidene fluoride (PVDF), 2.4 wt% solution in N-methyl-2-pyrrolidone or Nafion, 5 wt% solution in a mixture of lower aliphatic alcohols and water. Cyclic voltammetry measurements are done in several electrolytes to probe the intercalation of various cations such as magnesium, calcium, and aluminium. The best results are obtained when the electrode is cycled in 1M Al(NO3)3 aqueous solution.
This probably originates in different ionic radii.
During the process of electrode preparation, structural changes in the powder are noticed. The structural changes were followed step by step through the combined XRD and FTIR analysis. It turns out that the structure is prone to release water molecules even when the powder is mixed with carbon black and also with the addition of a solvent, which could lead to the formation of a bilayered vanadyl phosphate. It was shown that using different solvents has a diverse impact on the structure, and consequently on powders’ cyclic performances.

AB  - Layered vanadium oxides are, due to their adaptable interlayer distance and a multivalent state of vanadium, interesting electrode materials for various kinds of metal-ion batteries with both aqueous and nonaqueous electrolytes. In this study, a precursor solution adjusted for hydrothermal synthesis of sodium vanadate Na2V6O16, is modified by addition of carbon nanopowder Vulcan XC72, and this suspension is used for an one-pot hydrothermal synthesis of sodium vanadate/C composite. XRD analysis evidenced that the obtained composite is the mixture of two vanadate phases: Na2V6O16 and NaV6O15, instead of expected single-phase vanadate. SEM and TEM observations of composite revealed that these vanadate phases emerge in a form of both nanowires and nanospheres. The heterogeneity of phases and morphology of the composite is attributed to the directional action of carbon nanoparticles as a nucleation seed. The composite, used in aqueous Li-ion battery with LiFe0.95V0.05PO4/C cathode and LiNO3 electrolyte, displayed improved charge storage (220 mAh g−1 at current rate 150 mA g−1 in the initial discharge), after dc charging, in comparison to NaV6O15 or Na2V6O16 nanowire anodes. Furthermore, versatile insertion capability of this heterostructured composite towards mono (Li+, Na+) and multivalent (Ca2+, Mg2+, Al3+) ions in aqueous electrolytes is demonstrated by Cyclic Voltametry method, where the capacity stability depends on the type of cation, following the order Al3+, Li+, Mg2+, Ca2+. Upon 100 potentiodynamic chaging/discharging cycles, Ca2+ions display much better capacitance retention than Li+ ions (i.e., 64 vs. 13% of the initial value). The coinserted electrolyte constituents, H2O and OH− species, are considered to be responsible for the improved capacity retention, making vanadium ions less strained and less soluble. The pH, the concentration of the electrolyte and the type of anion are found to influence the cyclic behavior of observed vanadate composite in Ca-containing electrolyte. These results open a new directions in vanadate electrochemistry towards more sustainaible and cheaper aqueous batteries.

AB  - The capacitance and operating voltage of supercapacitors as well as their energy density have been increased by development of different materials and electrolytes. In this paper, two strategies, for the first time, were used to improve energy density: Mn3O4- and N-dual doped carbon electrode and aqueous mixture of multivalent ions as electrolyte. Mn3O4- and N-dual doped carbon was prepared by a novel and cost-effective procedure using deep eutectic solvent. XRD, XPS, and FTIR confirmed presence of Mn3O4 and nitrogen, while SEM and EDS elemental mapping showed micrometer-sized nanosheets with uniform distribution of C, O, N, and Mn atoms. Charge storage behavior of carbon was tested in aqueous multivalent-based electrolytes and their mixture (Ca2+-Al3+). Regarding both specific capacitance and workable voltage, the Ca2+-Al3+ mixed electrolyte was found as the best optimal solution. The calcium addition to the Al-electrolyte allows the higher operating voltage than in the case of individual Al(NO3)3 electrolyte while the addition of Al3+ ion in the Ca(NO3)2 electrolyte improves the multivalent-ion charge storage ability of carbon. As a result, the specific energy density of two-electrode Mn3O4@N-doped carbon//Al(NO3)2+Ca(NO3)2//Mn3O4@N-doped carbon supercapacitor (34 Wh kg−1 at 0.1 A g−1) overpasses the reported values obtained for Mn-based carbon supercapacitors using conventional aqueous electrolytes.

AB  - The development of carbon materials with desirable textures and new aqueous electrolytes is the key strategy to improve the performance of supercapacitors. Herein, a deep eutectic solvent (DES) was used for in situ templating of a carbon material. A carbon material was characterized (XRD, N2-physisorption, FTIR, SEM and EDS) and used as an electrode material for the first time in multivalent-based supercapacitors. In situ templating of carbon was performed using a novel DES, which serves as a precursor for carbon and for in situ generation of MgO. The generation of MgO and its roles in templating of carbon were discussed. Templating of carbon with MgO lead to an increase in surface area and a microporous texture. The obtained carbon was tested in multivalent-ion (Al3+ and Mg2+) electrolytes and compared with H2SO4. The charge-storage mechanism was investigated and elaborated. The highest specific capacitance was obtained for the Al(NO3)3 electrolyte, while the operating voltage follows the order: Mg(NO3)2 > Al(NO3)3 > H2SO4. Electrical double-layer capacitance (versus pseudocapacitance) was dominant in all investigated electrolytes. The larger operating voltage in multivalent electrolytes is a consequence of the lower fraction of free water, which suppresses hydrogen evolution (when compared with H2SO4). The GCD was experimentally performed on the Al(NO3)3 electrolyte, which showed good cyclic stability, with an energy density of 22.3 Wh kg−1 at 65 W kg−1.

AB  - Sodium ion batteries (SIB) present one of the most perspective post lithium technology and their progress strongly depends on the development of compounds having the structure which enables fast sodium insertion/deinsertion reactions. Polyanion compounds have been widely investigated as cathode materials for SIBs where they compete effectively to the usually used layered oxides. This survey is focused on the development of specific family of isostructural polyanion phases encompassed by the common chemical formula Na4M3(PO4)2(P2O7). The comprehensive retrospective of their synthesis procedures, the kinetics and mechanism of sodiation/desodiation reactions, based on both experimental and theoretical results, is provided. First, the review summarizes the structural properties of variety of Na4M3(PO4)2(P2O7) compounds in terms of its electrical, vibrational and surface properties. Then, the synthesis methods and sodium/lithium storage performance, of each type of Na4M3(PO4)2(P2O7) compounds, are chronologically presented and discussed. Finally, the strengths and weaknesses of these mixed polyanion cathodes are outlined, with the aim to explain some discrepancies and unclarified issues encountered in the literature. Besides, this survey will make room for future development. It can be very useful for the future design of high-performance mixed polyanionic compounds as cathodes for alkaline-ion rechargeable batteries.

AB  - Sodium ion batteries (SIB) present one of the most perspective post lithium technology and their progress strongly depends on the development of compounds having the structure which enables fast sodium insertion/deinsertion reactions. Polyanion compounds have been widely investigated as cathode materials for SIBs where they compete effectively to the usually used layered oxides. This survey is focused on the development of specific family of isostructural polyanion phases encompassed by the common chemical formula Na4M3(PO4)2(P2O7). The comprehensive retrospective of their synthesis procedures, the kinetics and mechanism of sodiation/desodiation reactions, based on both experimental and theoretical results, is provided. First, the review summarizes the structural properties of variety of Na4M3(PO4)2(P2O7) compounds in terms of its electrical, vibrational and surface properties. Then, the synthesis methods and sodium/lithium storage performance, of each type of Na4M3(PO4)2(P2O7) compounds, are chronologically presented and discussed. Finally, the strengths and weaknesses of these mixed polyanion cathodes are outlined, with the aim to explain some discrepancies and unclarified issues encountered in the literature. Besides, this survey will make room for future development. It can be very useful for the future design of high-performance mixed polyanionic compounds as cathodes for alkaline-ion rechargeable batteries.

AB  - Electrochemical and structural properties of LiV2O5 cathode were investigated. Obtained by solid state reaction at high temperature the material crystallized as gamma polymorph phase, γ-LiV2O5. The gamma structure provides two crystallographic sites to accommodate lithium ions, Li1 and Li2 position. Lithium insertion at these two sites occurs at two respective voltages versus lithium metal: ~3.6 V (Li1) and ~2.4 V (Li2). Intercalation at Li1 position is reversible in both organic and aqueous electrolyte and provides stable cycling performance at the high voltage. On the contrary, sluggish insertion/removal of Li+ at Li2 sites causes unstable performance and significant storage capacity fade at lower voltages. Lithium diffusion 3d landscape was determined by bond valence calculations applied on the γ-LiV2O5 phase, as well as on the metastable phases of γ′-V2O5 and ζ-Li2V2O5 that exist at high and low voltages respectively. The model was proposed based on inactivity of Li2 position of the metastable ζ-Li2V2O5 phase which provides explanation for the observed storage capacity loss at low voltages.

AB  - While the world is facing a higher demand for lithium, its limited resources associated with the high price, are becoming problematic. Other crucial drawbacks of Li-ion batteries are their toxicity and safety concerns. Therefore, researchers are oriented towards development of non-Li batteries based on eco-friendly and earth-abundant materials to overcome drawbacks of Li-ion technology. Alternative abundant metals and their ions such as Mg and Ca could be a good choice for rechargeable batteries in terms of cost and eco-friendliness. Mg2+ and Ca2+ ions could transfer two electrons per redox process which theoretically has a positive effect on battery performance. The materials upon which multivalent ions will intercalate with fast diffusion rate are hard to find. Metal vanadium oxide (MxVyOz) materials become promising materials for rechargeable batteries, so herein, a standard sol-gel combustion route was used for the preparation of the CaV2O6 layered precursor. Two samples are synthesized from the vanadate precursor, the first when it was heated at 400 °C (CaVO) and the second when CaVO was integrated with 10 wt % of sucrose under thermal treatment at 400 °C, in Ar atmosphere (CaVO/C). Obtained CaVO and CaVO/C powders were thoroughly characterized by XRD, TG-DTA, FTIR, and Raman spectroscopy. The electrochemical performance of the obtained samples was evaluated for multivalent-ion storage in saturated aqueous electrolytic solutions of Mg (NO3)2 and Ca (NO3)2 by cyclic voltammetry and chronopotentiometry. For comparison, measurements were also done in saturated LiNO3. Results indicated that CaVO can store more Li+ ions than Mg2+ and Ca2+ ions, but CaVO in LiNO3 shows a substantial loss of capacity upon cycling, which is not observed in the case of Mg (NO3)2 and Ca (NO3)2. On the other hand, CaVO/C composite showed a significant improvement for Ca an Mg storage capacity, which exceeded capacity storage of Li+ ions. The high and stable discharge capacity of CaVO/C, amounting to 89.3 mA h g−1 at 0.5 A g-1, was obtained in Ca (NO3)2. Obtained results are promising and open novel directions regarding the use of CaV2O6 for multivalent rechargeable batteries, especially for Ca-ion batteries.

AB  - Although today widely used in electronic devices and electric vehicles, lithium ion batteries encounter problem of future application, resulting from limited Li resources, relatively high costs and operational safety problems. Rechargeable magnesium batteries as a potential alternative to the Li-ion ones stand out because of their high theoretical specific capacity, high abundance of Mg resources, atmospheric stability, safety of handling, eco friendliness and low cost. Layered materials including oxides, sulphides and selenides are promising candidates for host materials for Mg2+ storage in rechargeable magnesium batteries. Slow migration of Mg2+ in the layered oxides, ascribed to the strong interaction between Mg and neighbouring O atoms, inspires researchers to look for the ways of improving their electrochemical performance. In this work, Mg-V-O material was synthesized by simple precipitation method, followed by thermal annealing. The obtained material is single-phase material consisted of MgV2O6 phase, according to the results of XRD, FTIR and Raman spectroscopy. Electrochemical test by cyclic voltammetry in aqueous solution revealed redox peaks corresponding to the insertion/deinsertion of Mg2+ ions into/from the material, but with poor current densities. In order to improve the electrochemical performance of the simply prepared Mg-V-O material, carbon was integrated with the Mg-V-O by sucrose-assisted thermal treatment. Although composed of several phases, the obtained Mg-V-O/C material exhibited around 40 times higher maximal specific current values of Mg2+ insertion/deinsertion than the Mg-V-O. Also, the electrochemical performance of the Mg-VO/ C for the insertion/deinsertion of Mg2+ ions was better than those of Al3+ and Li+ ions.
