A proprietary molten-salt electrolysis (MSE) process originally designed for battery manufacturing has now been re-optimized for North America’s first operational cobalt-refining plant. The DirectPlateTM MSE technology developed by Xerion Advanced Battery Corp. (Kettering, Ohio; www.xerionbattery.com; see Direct molten-salt electroplating cuts…
Biogas — produced from anaerobic digestion of organic matter — contains a mixture of gases, with methane and carbon dioxide as the predominant components. To use biogas as a fuel source, purification of the gas is typically needed to remove…
Researchers from the Lawrence Berkeley National Laboratory (Berkeley, Calif. www.lbl.gov), along with a host of collaborators, have made progress on an artificial photosynthesis system that converts CO2 into ethane and ethylene using nanostructured copper and perovskite. In a recent publication…
The ability to economically produce large scales of graphene will help to enable many high-performance applications, from smart packaging materials and medical devices to safer gas storage. A new process demonstrated at Southwest Research Institute (SwRI; San Antonio, Tex.; www.swri.org)…
Efficient and sustainable recycling of lithium-ion batteries is a crucial element in electrifying transportation. Black mass is a mixture of cathode and anode materials remaining after disassembly and shredding of end-of-life lithium-ion batteries (LIBs). Many valuable materials, including lithium and…
A dual process strategy bridging fermentation and electrochemistry is enabling the production of mid-chain carboxylic acids (MCCAs) — important and valuable precursors to a number of products — using inexpensive organic waste streams from breweries, distilleries and dairies. Developed by…
The extraction of alumina from bauxite is significantly impacted by the silica content of the ore — specifically the presence of silica in kaolinite (Al2Si2O5(OH)4). This is because traditional bauxite-beneficiation methods, such as washing, flotation and particle-size separation, also typically…
Aggregate — solid materials like sand, gravel and crushed stone — is combined with cement to make concrete, the world’s most widely used human-made material. But sand is in short supply, so there is a need for alternate materials to…
A new facility in Texas to manufacture high-purity graphene powder from acetylene has been announced by HydroGraph Clean Power Inc. (Vancouver, B.C.; www.hydrograph.com). At capacity, the facility will generate thousands of metric tons per year of sp2-bonded powdered graphene with…
Construction is planned for a pilot plant that will demonstrate a modular electrochemical technology for extracting rare-earth elements (REEs) and nickel from industrial wastes, such as coal ash. The startup Blueshift (Boston, Mass.; www.buildblueshift.com) recently announced venture capital funds that…
