Typically, to achieve the high graphite purity levels demanded by lithium-ion battery (LIB) applications, processors depend on hydrofluoric acid to remove silica impurities. Now, a new graphite-purification technology that eliminates the use of highly corrosive and toxic HF is being…
Kaji Technology Corp. (Osaka; www.kajitech.com) and Toray Industries, Inc. (Tokyo, both Japan; www.toray.com) have jointly completed developing and demonstrating an electrochemical hydrogen pump system earlier this year. This effort was part of a project, funded by the New Energy and…
Ethylene Toyo Engineering Corp. (Chiba, Japan; www.toyo-eng.com) has been awarded a contract for a project to construct an ethylene pilot plant, using waste-derived ethanol as raw material. The project is planned by Sumitomo Chemical Co. at its Chiba Works. Sumitomo…
A new demonstration plant will significantly scale up production of sustainable textile fibers made from cellulosic raw materials. TreeToTextile AB (Stockholm, Sweden; www.treetotextile.com), jointly owned by H&M Group, Inter IKEA Group, Stora Enso and LSCS Invest, has piloted a production…
A proprietary hydrometallurgical process known as Re-2Ox —originally conceived for the production of high-grade cobalt sulfate from mineral resources — is now showing promise in the field of battery recycling. “We did some preliminary test work and the technology was…
Last month, OMV AG (Vienna, Austria; www.omv.com) commissioned its ISO C4 demonstration isobutene plant at its Burghausen, Germany site. The plant is based on technology developed jointly by OMV and BASF SE (Ludwigshafen, Germany; www.basf.com), and has been producing high-purity…
As application demands evolve, battery materials have gotten more complex, incorporating not only lithium, but higher nickel, manganese and cobalt content, while also including various dopants like aluminum or zirconium and stabilizing coatings. Processing all of these disparate components into…
U.S. Vanadium LLC (Hot Springs, Ark.; www.usvanadium.com) has successfully demonstrated the ability to recycle the liquid electrolyte used in vanadium redox-flow batteries (VRFB), a rapidly growing commercial technology that promises to enable intermittent renewable energy technologies, such as solar and…
A closed-loop, long-duration energy-storage system (diagram) developed by Malta, Inc. (Cambridge, Mass.; www.maltainc.com) could provide a carbon-neutral path to industrial heating. “One of the exciting facets of this technology is that it generates a lot of discharge heat. When we…
Engineering design of a demonstration plant is underway for a process that pyrolyzes natural gas into hydrogen and solid carbon. The process was developed by C-Zero Inc. (Goleta, Calif.; www.czero.energy), a company set up in 2018 to develop and commercialize…
