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  - Vanadium-oxide-based materials exist with various vanadium oxidation states having rich chemistry and ability to form layered structures. These properties make them suitable for different applications, including energy conversion and storage. Magnesium vanadium oxide materials obtained using simple preparation route were studied as potential cathodes for rechargeable aqueous magnesium ion batteries. Structural characterization of the synthesized materials was performed using XRD and vibrational spectroscopy techniques (FTIR and Raman spectroscopy). Electrochemical behavior of the materials, observed by cyclic voltammetry, was further explained by BVS calculations. Sluggish Mg2+ ion kinetics in MgV2O6 was shown as a result of poor electronic and ionic wiring. Complex redox behavior of the studied materials is dependent on phase composition and metal ion inserted/deinserted into/from the material. Among the studied magnesium vanadium oxides, the multiphase oxide systems exhibited better Mg2+ insertion/deinsertion performances than the single-phase ones. Carbon addition was found to be an effective dual strategy for enhancing the charge storage behavior of MgV2O6. © 2022 by the authors.

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  - 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.

abstract = "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.

AB  - Lithium has a low abundance in the Earth's crust, which in a few years will lead to difficult lithium production, and therefore difficult production of lithium-ion batteries. Sodium-ion batteries, on the other hand, have been proven to be a good replacement. The material obtained from iron combined with the phosphate and pyrophosphate compounds of sodium has attracted attention as a possible cathode material for sodium-ion batteries. NaFePO4 exists in two polymorphic structures (triphylite and maricite). Maricite NaFePO4 is a more thermodynamically stable structure than triphylite NaFePO4 but doesn’t have channels for Na+ movement and electrochemical performance of this structure is low. In comparison to maricite NaFePO4, triphylite NaFePO4 (structural analogue to LiFePO4) has one-dimensional channels for Na+-ions movement and better electrochemical activity but it is not stable and is difficult to synthesize. Herein, the maricite NaFePO4 can be obtained by sintering a polyanionic compound, Na4Fe3(PO4)2P2O7, at temperatures above 600 °C, as shown by XRD. Na4Fe3(PO4)2P2O7 is synthesized by the glycine-nitrate process after which it was sintered at temperatures above 500 °C. The glycine-nitrate process was found to catalyze the decomposition of the sintered Na4Fe3(PO4)2P2O7 to the NaFePO4 maricite. The electrochemical characterization of the sintered material, evaluated in aqueous NaNO3 and LiNO3 electrolyte by cyclic voltammetry, showed poor electrochemical activity of maricite NaFePO4. By exposing the sintered material to high anodic potentials, the electrochemical activity and specific capacity of the material were increased by 50% in case of NaNO3 and 80% in case of LiNO3 relative to the pristine with low activity. After electrochemical measurements, residual powder was characterized by FTIR and Raman spectroscopy. It was shown that high anodic polarization of the material tested in LiNO3 causes the formation of triphylite LiFePO4. Similarly, it is assumed that the electrochemical activity obtained by deep anodic polarization of the material in NaNO3 electrolyte originates from the formed triphylite NaFePO4. The obtained results open novel directions regarding the use of NaFePO4 in metal-ion rechargeable batteries.
