Ceylon Graphite has completed full-cell testing using spheroidized vein graphite materials in commercial-size pouch cells, and the company says the results meet OEM specifications. Ceylon Graphite says that in 2021-2023 testing, its Sri Lankan vein graphite anodes outperformed industry-standard commercial synthetic graphite and had outstanding repeatability. They attained 161 mAh/g discharge capacity, compared to the… Read more »

Researchers say novel SEI-forming binder for graphite can improve fast charging performance
A team of researchers from the Japan Advanced Institute of Science and Technology (JAIST) has demonstrated a new fast-charging technique that promotes Li-ion intercalation of active material through the use of a novel binder material. According to the studies, the binder material improves desolvated Li-ion transport through the solid electrolyte interface (SEI) and within the… Read more »
Magnis to supply US-processed graphite anode material to Tesla
Tesla has entered into a Binding Offtake Agreement with Australia-based Magnis Energy Technologies, “a vertically integrated lithium-ion battery technology and materials company,” for anode active materials (AAM). Magnis is developing a graphite mine in Tanzania where it plans to extract “ultra-high-purity natural flake graphite.” Tesla plans to purchase at least 17,500 tons per year (tpa)… Read more »
A closer look at graphite—its forms, functions and future in EV batteries
Q&A with Graphex CEO John DeMaio Reading the EV press, you might assume that lithium, cobalt and nickel are the stars of the battery show—they get a lot of coverage, as pundits debate the relative merits of NMC and LFP cathode chemistries and agonize over looming shortages. Meanwhile, over in the anode, there’s an unsung… Read more »
Graphex and Northern Graphite partner to produce graphite anode material in North America
Graphex Technologies, a processor of specialized natural graphite, has signed a letter of intent with Northern Graphite to aggregate Northern’s raw material supply capabilities with Graphex’s downstream processing expertise to deliver an end-to-end supply of graphite from mine to battery while on-shoring a critical mineral supply chain to North America. Graphex and Northern intend to… Read more »
Nouveau Monde Graphite, Panasonic and Mitsui to develop graphite project in Québec
Nouveau Monde Graphite, Mitsui and Panasonic Energy have entered into a framework agreement to enable the next development steps of NMG’s ore-to-battery-market integrated graphite project in Québec. The deal includes a multi-year offtake agreement between NMG and Panasonic Energy for a significant portion of NMG’s active anode material. Also, an investment of US$50 million from… Read more »
LG Energy Solution and Syrah Resources collaborate on testing natural graphite
LG Energy Solution (LGES) will work with Syrah Resources on the testing and verification of natural graphite anode material. Syrah’s facility in Vidalia, Louisiana, which is slated to begin production in 2023, will supply the natural graphite. “Our partnership with Syrah demonstrates our devotion to diversifying the critical minerals portfolio by directly procuring from local… Read more »
Ionic MT says its nano-silicon can replace graphite in EV batteries, improving performance
Battery material technology company Ionic Mineral Technologies has emerged from stealth mode to debut its halloysite-derived nano-silicon, Ionisil, which is meant to be used as a drop-in replacement for graphite in lithium-based batteries. Ionic MT is a vertically-integrated producer of nano-silicon, which it says can enable significantly longer range and faster charging for EVs. The… Read more »
Nouveau Monde Graphite commissions coating line for graphite
Nouveau Monde Graphite (NMG) has completed phase 1 of a two-part plan by finishing a coating line for the production of coated spherical purified graphite and beginning cold commissioning of a kiln and utilities. “Coating helps create a stable electrolyte interface-layer in the battery system and increase initial coulombic efficiency and discharge capacity, thus extending… Read more »
Britishvolt secures government funding for battery cell gigaplant, selects synthetic graphite supplier
Battery manufacturer Britishvolt has secured additional funding from the UK government’s Automotive Transformation Fund for a new battery cell gigaplant in Northumberland. “While the overwhelming majority of investment for the project will come from private sources, the ATF’s grant funding is very important in proving that the UK Government is confident that we will deliver… Read more »
