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 »

Sunrise New Energy receives approval for two Na-ion anode patents for EV batteries

China-based Sunrise New Energy, a manufacturer of anode material, has announced that its subsidiary, Sunrise (Guizhou) New Energy Materials, has received preliminary approval from the National Intellectual Property Office for two separate patents related to anode materials for sodium-ion batteries. Sodium-ion batteries use hard carbon anodes, but low specific capacity, compactness, and expansion limitations plague… Read more »

Amprius offers samples of its new 400 Wh/kg silicon anode battery platform

Amprius Technologies has announced an expansion of its product portfolio of silicon anode batteries. The new SiCore batteries are based on a proprietary silicon anode material system. Amprius claims its batteries deliver performance that surpasses that of today’s state-of-the-art graphite-based cells: specific energy up to 400 Wh/kg, and cycle life up to 1,200 cycles at… Read more »

24M says its new separator tech eliminates dendrites in Li-ion batteries

Battery manufacturing technology provider 24M has unveiled a new battery separator tech called 24M Impervio, which the company says can make EV batteries substantially safer by inhibiting the growth of dendrites (rootlike metal growths that can build up on the anode surface, potentially causing a short-circuit that can lead to a fire). 24M’s Impervio technology… Read more »

GDI announces third-party cell verification of its 100% silicon anode

Battery-makers are eagerly researching ways to incorporate silicon, which can potentially store 10 times as much energy as graphite, into anodes. Now silicon anode specialist GDI says it has developed a 100% silicon roll-to-roll processed anode for next-generation batteries, potentially enabling graphite-free battery cells that deliver far higher energy density, faster charging and greater safety… Read more »
