Electrochemical Graphitization in Molten Salts (E-GRIMS): A Game Changer for Sustainable Graphite Production
Category: Other
Developers: Oak Ridge National Laboratory
Product Description:A cost-effective electrochemical process developed by ORNL and Solidion Technology Inc. can produce graphite from a variety of amorphous carbon sources. Demand and cost are growing for graphite, a critical material for energy storage devices. The process requires much less time and lower temperatures than the current commercial graphitization process. E-GRIMS enables the cost-effective production of high-quality graphite for a wide range of applications. Graphite is a critical material used in steelmaking electrodes, nuclear fuel cladding, and lithium-ion battery anodes. Global graphite consumption is estimated at 3 million tons per year, with prices ranging from $2,000 to $20,000 per ton, depending on quality. As natural graphite becomes increasingly scarce, the current industrial production method—based on a 200-year-old technology—remains slow, energy-intensive, and expensive. This underscores the need for a new graphitization approach capable of producing high-quality graphite from abundant amorphous carbon precursors. E-GRIMS addresses this need by producing graphite at lower temperatures, reduced costs, and shorter processing times than existing technologies. It offers tunability over key properties such as d-spacing and degree of graphitization, and, unlike conventional methods, it can graphitize virtually all carbon precursors. This flexibility allows the production of various graphite grades tailored for specific applications, including sustainable electric vehicle manufacturing and grid energy storage.
