Graphite mining and product company Ceylon Graphite has announced test results for its silicon-enhanced vein graphite anode material. In independent tests performed by Warwick University, Ceylon’s silicon-enhanced vein graphite yielded a specific discharge capacity (SDC) of 446 mAh/g in comparison to vein graphite’s typical SDC of 393 mAh/g. Ceylon’s 13% higher SDC was achieved in… Read more »

NOVONIX aims to reduce mining emissions with its GX-23 synthetic graphite product
Based on a life-cycle assessment being performed by sustainable mining specialist Minviro, NOVONIX says preliminary results suggest that its GX-23 synthetic graphite anode product generates a 60% decrease in CO2 emissions compared to graphite mining in two areas of China. The unfinished life-cycle assessment, which has not been subjected to third-party peer review, compared GX-23… Read more »
Syrah Resources to supply Tesla with natural graphite active anode material
Australia-based Syrah Resources has signed a binding offtake agreement with Tesla to supply natural graphite Active Anode Material (AAM) from its vertically integrated AAM production facility in Vidalia, Louisiana. Tesla will buy the majority of the proposed initial expansion of AAM production capacity at Vidalia at a fixed price for an initial term of four… Read more »
Battery testing start-up Novonix has spun off PUREgraphite to manufacture anode material in the US
Batteries are ubiquitous in our modern lives. Take a look around you and count how many items need be plugged in and recharged. If you’re at your desk, the answer might be four or five. If you’re out for a run, perhaps two or three. If you’re in a garage, there may only be one,… Read more »
Researchers demonstrate Li-ion anode with silicon-nanolayer-embedded graphite/carbon
Larger figure Researchers from South Korea’s Ulsan National Institute of Science and Technology (UNIST) and Stanford University have demonstrated the feasibility of a hybrid anode for Li-ion batteries using silicon-nanolayer-embedded graphite/carbon. In “Scalable synthesis of silicon-nanolayer-embedded graphite for high-energy lithium-ion batteries,” published in Nature Energy, Minseong Ko and colleagues explain that this architecture allows compatibility… Read more »
Chinese researchers develop aluminum-graphite dual-ion battery
A team from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences has developed a novel, environmentally friendly low-cost battery. In “A Novel Aluminum-Graphite Dual-Ion Battery,” published in Advanced Energy Materials, Yongbing Tang and colleagues present a new aluminum-graphite dual-ion battery (AGDIB) that they say offers higher energy density than conventional LIBs, as… Read more »
Talga enters US battery anode market through partnership with United Catalyst
Battery materials and technology company Talga has signed a strategic cooperation agreement with United Catalyst, marking its entry into the US market and laying the groundwork for potentially building new battery graphite recycling and anode facilities. The three-year agreement combines UCC’s capabilities in automotive recycling with Talga’s expertise in battery graphite and anode materials. The… Read more »
Nuvvon battery with solid polymer electrolyte passes nail penetration tests
US solid-state battery technology developer Nuvvon’s polymer electrolyte has passed a series of nail penetration tests, which create a short circuit inside the cell to determine if the battery catches fire or explodes. In two sets of tests, which were conducted at The University of Texas at Austin (UTA), traditional 1 Ah cells of commercial… Read more »
Video: Schaeffler’s all-solid-state battery module and other eMobility innovations
At this year’s Battery Show in Detroit, Charged spoke with four of Schaeffler’s subject-matter experts to explore the company’s innovations in electrification and energy storage. The discussion began with Rashid Farahati, Vice President of the Corporate Competence Center for the Americas. Farahati explained that while solid-state batteries promise higher energy density, safety and faster charging,… Read more »
Ateios Systems and Kodak unveil solvent-free battery electrode manufacturing process
Battery electrode supplier Ateios Systems has teamed up with materials and chemicals manufacturer Kodak to demonstrate a high-speed, solvent-free production process for the manufacturing of high-energy electrodes for EV batteries. The system, powered by Atelos’s RaiCure platform, reaches a coating speed of 80 meters per minute, which the companies say is nearly three times faster… Read more »
