Layered transition-metal oxides are among the most promising cathode materials for sodium-ion batteries because of their high theoretical capacity and low cost. However, conventional designs rely on ...

Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their ...

The new redox Sulfint HP process desulfurizes natural gas efficiently at high pressures. The process, developed by Institut Français du Pétrole (IFP) and Le Gaz Intégral (LGI) in association with Le ...

Iron-chromium redox flow batteries are pivotal in addressing the challenges of renewable energy sources, such as solar and wind, which often suffer from inconsistency in energy supply. These batteries ...

An international research team has developed a new concept for redox flow batteries that uses iron and chromium ore for redox chemistry. “We are in the preliminary stages of exploring the economic ...
