Graphex Group to increase graphite production in China
Graphite and graphene enrichment company Graphex Group plans to expand its production of spherical graphite (SG) and coated spherical graphite (CSG) in Jixi City. Beginning in early 2023 and continuing for the next three years, Graphex Group says it will expand its annual production of SG from 10,000 to 40,000 tons per year. The company… Read more »
Ascend Elements says it can extract 99.9% pure graphite from used Li-ion batteries
Ascend Elements, a vertically integrated battery recycling and engineered materials company, and Koura, a producer of fluoroproducts, have announced the launch of a proprietary process that yields battery-grade graphite material from spent lithium-ion batteries. Koura’s parent company Orbia is serving as a development partner to Ascend Elements to scale the company’s technology for commercial production,… Read more »
Ceylon Graphite’s silicon-enhanced vein graphite shows increased discharge capacity
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 »
