We report the temperature dependence of the average structures of 0.4Li2MnO3–0.6LiMn1/3Ni1/3Co1/3O2 during the 5th discharge process, where the structures are characterized via neutron and synchrotron X-ray diffraction analyses. In the cycle tests

Here, we propose a two-step pervaporation system with a high-silica CHA (chabazite) membrane, which has sufficient resistance to water and acid, to demonstrate the extraction and condensation of the formic acid formed by electroreduction of CO2. The

Abstract In this work, we focus on Mg–Fe–O and Mg–Ni–O with Mg-rich compositions as positive-electrode materials for magnesium rechargeable batteries, and prepare them by a thermal decomposition of precipitates obtained by a solution method.

La2NiO4+δ-based materials with a layered perovskite structure have attracted significant attention as air–electrode materials for use in solid oxide fuel cells. In particular, Ca-substituted materials, La2-xCaxNiO4+δ, have been investigated, as t

In this study, the projected density of states (PDOS) of the stable normal-spinel structure and stable Mg/Co mixed-cation spinel structure of Mg1+yCo2−xMnxO4 (x = 0, 0.5; y = 0, 0.5, 1) in the pristine and discharged states are obtained using first

We studied the average crystal structural change during charging and discharging of a 0.4Li2MnO3-0.6LiMn1/3Ni1/3Co1/3O2 battery cathode in combination with a Li-metal anode, graphite anodes, and three types of separators. Prelithiation of the graphit

It is widely recognized that heat-resistant separators improve the safety of lithium-ion batteries. However, it is not clear how the separator contributes to battery safety, or how much heat resistance is required. The state of separators when a shor

In the present study, αMgCo1.5Mn0.5O4-(1 − α)Mg1.33V1.57Ni0.1O4 was synthesized by a reverse co-precipitation method. The products were assigned to a spinel structure with a space group Fd3m based on powder X-ray diffraction analysis. Inductively
