High‐Resolution Mapping of Discharge Product in Li─O2 Batteries

Small Methods, EarlyView.
Li─O2 batteries promise exceptional energy density, but have several factors limiting performance, such as poor rate performance. To understand rate limitations, scanning electron microscopy with energy dispersive X‐ray spectroscopy and X‐ray nano‐computed tomography were employed to map the distribution of discharge products in discharged air ...

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, EarlyView.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.
