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  - Water electrolysis represents a simple and clean method for production of hydrogen and oxygen. Nickel is a promising electrode material for large-scale application. Its activity could be improved by alloying it with other metals, non-metals or rare earth elements, or by fabrication in the form of foams or nanostructured composites, grafting onto a high surface area support, etc.
In this study, Ni2+ cation-exchanged zeolites NiA and NiX were tested as electrocatalysts for hydrogen and oxygen evolution reactions (HER and OER) in alkaline media (1 M KOH). Conventional ion-exchange procedure was used to prepare Ni2+ cation-exchanged forms of NaA and NaX zeolites. The obtained materials, NiA and NiX, are described by formula Ni6(AlO2)12(SiO2)12 and Na23Ni32(AlO2)87(SiO2)105, respectively.
XRD analysis generally confirmed the crystalline structure of the studied materials. In the case of NiA, broadening of diffraction peaks at 2θ angle of 11, 24 and 35o indicated partial distortion of the zeolite crystal lattice during ion-exchange process.
Electrocatalitic activity of NiA and NiX for HER and OER was studied in 1 M KOH by recording polarization curves, chronoamperograms and electrochemical impedance spectra. For both reactions, NiA exhibited better catalytic activity than NiX, including higher current density and lower Tafel slope values. This could be correlated with higher Ni weight fraction in NiA than in NiX, and with higher electrical conductivity of NiA. Analysis of the electrochemical impedance spectra revealed that the HER is controlled by adsorption of the Hads intermediate, while the OER is controlled by the charge transfer at the potentials of interest for the process. Relatively good stability of both materials during HER and OER was deduced from the chronoamperometric curves.
