Abstract Four proton conducting oxides of perovskite structure: BaZrO3, SrZrO3, BaCeO3 and SrCeO3 doped with 5 mol.% gadolinium are compared in terms crystal structure, microstructure, sinterability, water sorption ability, ionic transference number, electrical conductivity stability towards CO2. Relations between conductivity, structural chemical parameters: pseudo-cubic unit cell volume, lattice free tolerance factor, symmetry electronegativity discussed. The grain boundary resistance is...
A series of the high-entropy (Co,Cu,Mg,Ni,Zn)1-xLixO oxides with a lithium substitution level x = 0, 0.05, 0.10, 0.15, 0.20, 0.25, and 0.30 is evaluated in terms crystal structure, morphology transport properties, thorough studies aimed at elucidation nature different contributions to total electrical conductivity. It found that cubic Fm-3m structure preserved whole investigated series, (Co,Cu,Mg,Ni,Zn)0.8Li0.2O composition showing high internal strain, supporting some degree one so-called...
Ordering in the transition metal sublattice O3 phase affects density of states near E F . Due to low conductivity its presence causes stronger polarization electrode and makes P3 → change unfavourable.
LiFePO4 is considered to be one of the most promising cathode materials for lithium ion batteries electric vehicle (EV) application. However, there are still a number unsolved issues regarding influence Li and Fe-site substitution on physicochemical properties LiFePO4. This review-type article, presenting results our group, related possibility chemical modification phosphoolivine by introduction cation dopants in Fe sublattices. Along with synthetic review previous papers, large new...
A new method of synthesis stoichiometric Na<sub>2</sub>FeM(SO<sub>4</sub>)<sub>3</sub> (M = Fe, Mn, Ni) materials is developed.
In this study, various techniques, such as energy-dispersive X-ray spectroscopy (EDX), diffraction (XRD), Raman spectroscopy, and spectrophotometry, were used to analyze the properties of nanometric CdS particles synthesized with varying precursor concentrations. EDX analysis revealed nonstoichiometric composition manifested by an increase in Cd/S ratio from 1.02 up 1.43 increasing concentration. The growth lattice parameters unit cell volume accompanying preferential crystallization...
Given the extensive efforts focused on protecting environment, eco-friendly cathode materials are a prerequisite for development of Na-ion battery technology. Such should contain abundant and inexpensive elements. In paper, we present NASICON-Na3Fe2-yMny(PO4)3 (y = 0, 0.1, 0.2, 0.3, 0.4) materials, which meet these requirements. Na3Fe2-yMny(PO4)3 compounds were prepared via solid-state reaction at 600 °C, allowed to obtain powders with submicron particles. The presence manganese in iron...
Abstract In this work, we report that modification of the chemical composition grain boundaries La 2/3-x Li 3x TiO 3 double perovskite, one most promising Li-ion conducting solid electrolytes, can be a convenient and versatile way controlling space charge potential, leading to mitigated electrical resistance boundaries. Two groups additives are investigated: lithium-enriching agents (Li BO , LiF) d metal ions (Co 2+ Cu ), both expected reduce Schottky barrier. It is observed Li-containing...
