The structure and physical properties of (50−x)Li2O·xFe2O3·50P2O5 glasses (0 ≤ x ≤ 25 mol%) have been studied by different techniques. The amorphous nature of the glasses has been affirmed by x-ray diffraction. By increasing Fe2O3 content, the Fe/P ratio increases, and the covalent P–O–Fe bonds also increase, which leads to a more durable structure. For Fe2O3 ≤ 15 mol%, Fe ions enter the network as a network modifier breaking P–O–P and P = O bonds and act as a network former for Fe2O3 > 15 mol%. Hardness (H v) increases with increasing Fe2O3 content because of the strengthening of the network. Studying the chemical durability of the investigated glasses has shown that the compositions containing high content of iron oxide are more water−resistant. Moreover, density and molar volume increase with different rates with Fe2O3 content. It is believed that the conduction in these glasses is predominantly ionic and dominated by Li+ ions as the main charge carriers. The contribution of the polarons to the conduction process has a negligible impact compared to that of the ionic conduction by Li+ ions. Regarding the shielding properties, the mass attenuation coefficient was calculated by the XCOM program and other photon shielding properties like mean free path (λ), and half value layer (HVL) were calculated within the energy range of 0.335 MeV-9 MeV. The effect of replacing lithium oxide by iron oxide has been analyzed which proved that iron is more efficient than lithium in attenuating and removing fast neutrons.

Magnetically active lithium-ion batteries towards battery performance improvement

et al. 2021

Lithium-ion batteries (LIBs) are currently the fastest growing segment of the global battery market, and the preferred electrochemical energy storage system for portable applications. Magnetism is one of the forces that can be applied improve performance, since the application of magnetic fields influences electrochemical reactions through variation of electrolyte properties, mass transportation, electrode kinetics, and deposits morphology. This review provides a description of the magnetic forces present in electrochemical reactions and focuses on how those forces may be taken advantage of to influence the LIBs components (electrolyte, electrodes, and active materials), improving battery performance. The different ways that magnetic forces can interact with LIBs components are discussed, as well as their influence on the electrochemical behavior. The suitable control of these forces and interactions can lead to higher performance LIBs structures and to the development of innovative concepts.

“…Steel slag, a by-product of steelmaking, is a resource that can be recycled and used as raw material for cement, concrete, and glass ceramics. [1][2][3] At present, the modification of steel slag to prepare fiber materials is regarded as a high value-added utilization method. Molten steel slag is poured directly into the reduction container, and, after complete reduction, is poured in a rotating barrel for slag fiber production by centrifugal force.…”

The kinetic behavior of SiO 2 dissolving in molten steel slag at 1 773-1 923 K was studied using a combination of high-temperature confocal scanning laser microscopy and a synthetic physical property tester. The experimental results showed that the change in slag electrical conductivity can characterize the homogenization process of the modifying agent in molten steel slag, and the dissolution process of the modifying agent is controlled by solute diffusion in the slag. The concentration difference between the boundary layer and the bulk of the slag is the primary driving force of the dissolution process. By increasing the reaction temperature, the SiO 2 particle dissolution rate in slag can be significantly increased. Moreover, the experimental data and model calculations revealed that the SiO 2 dissolution rate was the fastest when the total Fe (T.Fe) content was 14% and the acidity coefficient (M k ) was 1.5. The dissolution factors were defined to quantitatively evaluate the dissolution mechanism of particle by studying the dissolution process of slag with different components.
