Electrochemical investigations of decorated graphite felt electrodes with Nafion/TiO2 nanoparticles for vanadium redox flow battery: Improving electro-catalytic characteristics Mahboobeh Azadi, Mohammad Zarei-Jelyani, Mohammad Mohsen Loghavi, Mohsen Babaiee, Rahim Eqra Open Ceramics, 2024 • Newly decorated graphite felt electrodes with TiO 2 -nanoparticles were made. • The optimum percentage of TiO 2 -nanoparticles in the matrix was 3 g/L. • The reversibility of redox reactions increased by about 44%. • The over-potential in vanadium redox flow battery was reduced by about 84%. • TiO 2 -nanoparticles were distributed homogeneously on graphite felts. The present study aimed to investigate the effect of Nafion/TiO 2 nanoparticles as an electrocatalyst on the electrochemical behavior of graphite felt (GF) electrodes in a vanadium redox flow battery. Various electrochemical tests, including cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and linear sweep voltammetry (LSV), were conducted to assess the performance of these electrodes at different concentrations of nanoparticles (2-4 g L -1 ). Additionally, X-ray diffraction, Fourier transform infrared spectroscopy, and field emission scanning electron microscopy were employed to analyze the chemical composition, bonding, and morphology of the decorated electrodes, respectively. The CV results revealed several effects of TiO 2 nanoparticles on the GF electrode, such as increased peak intensity and shifted peak sites. As the concentration of nanoparticles increased, the peak intensity rose by up to 44%. Moreover, the potentials of the decorated electrodes shifted towards the favorable side compared to the GF electrode, with changes ranging from 18 to 84%. Overall, the optimal concentration of TiO 2 nanoparticles (3 g L -1 ) exhibited excellent electrode performance, characterized by the highest calculated diffusion coefficient, greater reversibility, enhanced electron transfer kinetics, improved stability, lower over-potential, and the lowest activation energy for redox reactions. EIS results demonstrated a significant decrease in polarization resistance (67.2-70.8%) for the decorated electrodes. Furthermore, LSV measurements indicated that the utilization of nano-electrocatalysts effectively inhibited hydrogen evolution at negative potentials.
Al2O3-coated LiNi0.8Co0.15Al0.05O2/graphene composite as a high-performance cathode material for lithium-ion battery Mohammad Mohsen Loghavi, Mohsen Babaiee, Rahim Eqra Main Group Chemistry, 2023 A cathode material composite containing Al2O3-coated LiNi0.8Co0.15Al0.05O2 (NCA) and graphene was prepared via a combination of ultrasonication and mechanical ball milling. No changes were observed in the crystalline structure of this material relative to the bare and Al2O3-coated LiNi0.8Co0.15Al0.05O2 materials based on the XRD spectrum. SEM images indicated that graphene was well distributed between the active material particles. The composite material was compared with the bare and Al2O3-coated active materials by electrochemical tests to evaluate its performance in the lithium-ion battery. The resistance values of the solid-electrolyte interphase layer and charge transfer were investigated during cycling by electrochemical impedance spectroscopy. The composite material provided the lowest resistance values with high stability during cycling. The capacity retention of the composite material was 27.7% more in comparison to the bare material during 50 cycles of charge/discharge at a 0.5C rate. Remarkably, the rate capability was improved by using the composite material, with a specific capacity of over 130.9 mAh g–1 at a 3C rate, which means delivering 62.9 mAh g–1 more capacity than the bare NCA. Graphene improved capacity retention and rate capability through the creation of a protective layer on the particles and providing a conductive medium in the electrode structure.
