AB  - Anatase TiO2 nanotube arrays of different morphology were prepared by a two-step process: anodic oxidation at voltages 20-60 V and subsequent annealing at 400 degrees C. By amplifying anodization voltage the inner diameter of nanotubes increased. At 60 V nanotubes changed the shape from cylindrical tube to truncated cone with elliptical opening. Electrochemical insertion of Li-ion in nanotubes was studied by cyclic voltammetry and galvanostatic charge-discharge experiments. The cyclovoltammetric response was fast for all nanotube arrays. The galvanostatic areal charge/discharge capacity of nanotube arrays increased with increasing anodizaton voltage. Although the mass of nanotubes prepared at 45 V was larger, the gravimetrical capacity was much higher for nanotubes prepared at 60 V because of the larger surface area exposed to the electrolyte. Gravimetrical capacity values exceed theoretical bulk capacity of anatase due to the surface storage of Li-ion. Diffusion coefficient of Li-ion was calculated to be between 5.9.10(-16) and 5.9.10(-15) cm(2) s(-1). (C) 2017 Elsevier B.V. All rights reserved.

AB  - Raman scattering (RS), Fourier transform infrared (FTIR) and electron paramagnetic resonance (EPR) spectroscopic measurements on beta-MnO2 and alpha-KxMnO2 nanorods were performed. The infrared spectrum of beta-MnO2 is sensitive towards the particle sizes, while the Raman spectrum is sensitive towards the presence of nonstoichiometric and disordered MnO2-delta on the surface of nanorods. EPR measurements show the appearance of two types of Mn4+ ions having different local environment: (i) Mn4+ ions in Mn4+-rich environment and (ii) Mn4+ ions in mixed-valence Mn4+/Mn3+ environment that match up with region of nonstoichiometric MnO2-delta. Observed bands in vibrational spectra of tetragonal hollanditetype alpha-KxMnO(2) are considered to be mainly due to the vibration modes of Mn-O frameworks. The EPR spectra of alpha-KxMnO(2) nanorods contain two signals that can be attributed to Mn4+ ions in Mn4+-rich environment and Mn4+ ions in mixed-valence Mn4+/Mn3+ environment close to K+ ions.

AB  - Magnetic properties of Fe2O3/SiO2 samples were studied after being produced by sol-gel synthesis and formation of epsilon-Fe2O3 polymorph. Samples were thermally treated, using different annealing temperatures and annealing times. The size and morphological characteristics of the iron oxide nanoparticles were examined using a TEM microscope. We used the ellipticity of shapes, which is a measure of how much the shape of a nanoparticle differs from a perfect ellipse, in order to quantitatively describe morphological properties of nanoparticles. Coercivity measurements were used to identify and monitor the formation of the epsilon-iron oxide phase during the thermal treatments (annealing). Coercivity values were in the range from 1.2 to 15.4 kOe, which is in accordance with previous experience regarding the existence of epsilon-Fe2O3. We have determined the optimal formation conditions for the epsilon-Fe2O3 polymorph (t=1050 degrees C for 7 h, H-c=15.4 kOe), as well as the narrow temperature interval (1050-1060 C) in which the polymorph abruptly vanished (H-c=2300 Oe), on the basis of results of the magnetic properties. The threshold temperature for the epsilon-Fe2O3 phase transformation was measured as 1060 degrees C. We found that different annealing temperatures and annealing times significantly affected magnetic properties of the examined samples.

The paper offers experimental proofs of the theoretical prediction that fluorine doping of LiFePO4 can enhance its electrical conductivity. The LiFePO4 and fluorine-doped LiFePO4 olivine type, carbon free powders are synthesized and examined. The crystal structure refinements in the Pnma space group reveal that doping with fluorine ions preserves the olivine structure, while reducing both the lattice parameters and the antisite defect, and increasing the crystallite size.

After 50 cycles, the capacity fade was 4 %, but from 20th-50th cycle, no capacity drop was observed. The VO2(B) showed very good cyclability at a current rate of even 1000 mA g(-1) with initial discharge capacity of 92 mAh g(-1). The excellent electrochemical performance of VO2(B) was attributed to the stability of micro-nano structures to a repeated intercalation/deintercalation process, very good electronic conductivity as well as the very low charge transfer resistance in an aqueous electrolyte.

AB  - Olivine-type LiFePO4 composite powders with carbon were synthesized by freeze drying and subsequent thermal annealing. The main purpose of the research is to explore how various dicarboxylic acids as carbon sources influence the electrochemical properties of the resulting composites. Three dicarboxylic acids (oxalic, malonic, and adipic) were used as a carbon source.

It is shown that the amount of the in situ formed carbon depends on the thermal behaviour of the acids in inert atmosphere rather than on their carbon content. Cyclic voltammetry experiments and galvanostatic cycling illustrate the behaviour of different powders: the powder obtained with oxalic acid yields the highest discharge capacity at small currents, while the one obtained with adipic acid shows better high-current response. Malonic acid has turned out to be a poor carbon source and it consequently yields powder with poor electrochemical performance. (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

abstract = "Olivine-type LiFePO4 composite powders with carbon were synthesized by freeze drying and subsequent thermal annealing. The main purpose of the research is to explore how various dicarboxylic acids as carbon sources influence the electrochemical properties of the resulting composites. Three dicarboxylic acids (oxalic, malonic, and adipic) were used as a carbon source. The synthesis was followed by X-ray powder diffraction, scanning electron microscopy, particle-size analysis, and electrochemical experiments. It is shown that the amount of the in situ formed carbon depends on the thermal behaviour of the acids in inert atmosphere rather than on their carbon content.

AB  - This work presents the synthesis of F-doped LiFePO4/C composite by the specific modification of the recently suggested synthesis procedure based on an aqueous precipitation of precursor material in molten stearic acid, followed by a high temperature treatment. Besides the lattice parameters and the primitive cell volume reductions, compared to the undoped sample synthesized under the same conditions, the Rietveld refinement also shows that fluorine ions preferably occupy specific oxygen sites. Particularly, the best refinement is accomplished when fluorine ions occupy O(2) sites exclusively. By means of up-to-date electronic structure and total energy calculations this experimental finding is theoretically confirmed. Such fluorine doping also produces closing of the gap in the electronic structure and consequently better conductivity properties of the doped compound. In addition, the morphological and electrochemical performances of the synthesized powder are fully characterized. (C) 2013 Elsevier B.V. All rights reserved.

The X-ray diffraction experiments confirmed the spinet structure of Li4Ti5O12 in all samples. The carbon content altered significantly the morphology of obtained micro/nanoparticles. The Li4Ti5O12/C composite with the high carbon content showed the highest electrical conductivity (2.0 S cm(-1)), and displayed also extraordinary electrochemical performance: the cyclovoltammograms consisted of well defined reversible redox peaks at a scan rate as high as 10 mV s(-1), while, by galvanostatic cycling, the coulombic capacity of 150 mAh g(-1) was evidenced at a discharging rate of 10 C.

The two-phased Rietveld refinement confirmed that vanadium incorporation into olivine structure was complete. The heating under reduction atmosphere caused the formation of iron phosphide to some extent, the concentration was determined by Rietveld analysis. The capacity and rate capability of these composites were tested by both cyclic voltammetry and galvanostatic cycling. Specifically, the average discharging capacities of the composite with x=0.055, determined in an saturated aqueous LiNO3 solution equilibrated with air, at the rates of 1, 10 and 100 C, amounted to 91, 73 and 35 mAh g(-1), respectively, with no perceivable capacity fade.

Structural characterization of produced nanocomposite was done by X-ray powder diffraction (XRD), particle size analysis and scanning electron microscopy (SEM). The structure and morphology of the composite have been correlated with hydrogen desorption properties investigated by differential thermal analysis (DTA). It has been shown that short mechanical milling of nanostructured VO2 and MgH2 leads to decrease of hydrogen desorption temperature of MgH2 by 80 K. The mechanism of desorption has been changed from phase boundary reaction, spherical symmetry for untreated MgH2 to phase boundary reaction, cylindrical symmetry for the composite material. The activation energy for desorption has been reduced by adding VO2 ceramics as a catalyst. (C) 2012 Elsevier Ltd and, Techna Group S.r.l. All rights reserved.

AB  - The influence of the heat treatment on the structural and magnetic properties of the nanoparticle La0.7Ca0.3MnO3 compound has been studied. The starting single-phase sample was prepared by the glycine nitrate method without additional heating. The as-prepared specimen has been afterward annealed at two different temperatures of 600 C and 900 degrees C. All three samples where characterized by XRPD, SEM and TEM, as well as by the SQUID magnetometry. Rietveld analysis of the XRPD data showed the orthorhombic perovskite structure (space group Prima) of all the samples, while the unit cell parameters underwent a contraction with the annealing temperature. The influence of the heat treatment on the crystal structure is to decrease the orthorhombic distortion by changing the geometrical parameters. The TEM micrographs showed the increase of the mean particle size with annealing temperature from 10 nm up to 50 nm. DC magnetization and AC susceptibility measurements revealed the change of magnetic properties with the increase of the particle size: both para-to-ferromagnetic transition temperature T-C and saturation magnetization M-S were shifted to higher values with the simultaneous decrease of the coercivity H-C. In addition, annealing procedure suppresses the spin-glass-like state that emerges in the as-prepared sample below T-f = 95K. (C) 2010 Elsevier B.V. All rights reserved.

AB  - By dissolving crystalline V2O5 in hydrogen peroxide and drying at elevated temperature, the V2O5 xerogel was obtained. Its electrochemical behaviour was examined in aqueous solution of LiNO3 by both cyclic voltammetry and galvanostatic charging/discharging cycling. Peak-to-peak potential separation observed at the cyclovoltammograms indicated fast Li+ intercalation/deintercalation reactions. Initial discharge capacity amounted to 69 mAhg(-1), and after 100 charging/discharging cycles, capacity fade amounted to 11% only. This presents a remarkable improvement in comparison with the behaviour of crystalline, vanadium oxide based, lithium intercalates in aqueous electrolytes. (c) 2009 Elsevier B.V. All rights reserved.

AB  - Lithium iron phosphate has become of great interest as storage cathode for the next generation of rechargeable lithium batteries. Olivine structure LiFePO(4)/C composite powder was prepared by ultrasound assisted synthesis. A polyvinyl alcohol solution was used as the source of an in situ formed carbon. X-ray powder diffraction confirmed the phase purity. X-ray powder diffraction data were used for the crystal structure refinement, based on Rietveld full profile method. All relevant structural and microstructural crystal parameters that could be significant for electrochemical intercalation/deintercalation processes were determined. The Rietveld refinement also showed additional electron density on the lithium sites, indicating 3 at.% iron on the lithium site. Electrochemical characteristic of the composite was evaluated by using galvanostatic charge/discharge tests. While cycling at C/3 (C/10) rate the discharge capacity increases, starting from the value of 94.1 (116.0) mAh/g and reaching 99.5 (124.0) mAh/g at the end of the cycling. Particle morphology was revealed by both scanning and transmission electron microscopies. On the thin particle edges carbon film with a typical thickness of several nanometers can be observed, as well as small carbon agglomerates (typical size LT 6 nm) at certain spots on the substrate surface.

AB  - Comparative crystal structure and magnetic properties studies have been conducted on quaternary powder spinel samples LiMn1.82Cr0.18O4 obtained by two different synthesis methods, glycine-nitrate (GN) and ultrasonic spray-pyrolysis (SP). Although both samples possess the same spinel structure of the cubic space group Fd (3) over barm, their low-temperature magnetic properties display significant differences. While the SP sample undergoes only spin-glass transition at the freezing temperature T-f 20 K, the GN sample possesses more complicated low-temperature magnetic behavior of the reentrant spin-glass type with the Neel temperature TN 42K and freezing temperature Tf 22 K. High-temperature magnetic susceptibility of both samples is of the Curie-Weiss type with the effective magnetic moments in agreement with the nominal compositions. This fact together with the results of the chemical analysis discards the existence of the diversity in chemical compositions as a possible cause for the observed differences in the low-temperature magnetism. On the other hand, the crystal structure analysis done by the Rietveld refinement of the X-ray powder diffraction data points to the strong influence of the cation distribution on the ground-state magnetism of these systems. An explanation of this influence is proposed within the framework of a collective Jahn-Teller effect. (C) 2007 Elsevier B.V. All rights reserved.

AB  - Cyclic voltammetry (CV) of LiCr0.15Mn1.85O4, synthesized by rapid glycine-nitrate method (GNM), was performed in a saturated aqueous LiNO3 (similar to 9 M) solution. At rather high polarization rate of 10 mV s(-1) two well separated characteristic pairs of redox peaks can be clearly observed, which is not entirely the case for LiMn2O4 synthesized in the same way. At a reduced scan rate of 1 mV s(-1), the shape and position of redox peaks evidence that deintercalation/intercalation of Li+ ion is highly reversible and much faster than in the case of organic electrolytes. Faster CV response of LiCr0.15Mn1.85O4 is in correlation with higher capacity retention (93%) in comparison to LiMn2O4 (88%), registered after 50 charging/discharging cycles in organic electrolyte solution (1 M LiClO4 in propylene carbonate).
