  • Nouveau Monde has received important and impressive test results for its advanced graphite-based anode materials.
  • Nouveau Monde’s anode material has outperformed leading Asian commercial producers – the Company’s reversible capacity (or energy density) performed at 365 mAh/g, above the 360 mAh/g of Asian peers, with similar charging efficiency, and well above the minimum customer specifications requirement of 350 mAh/g.
  • Multiple samples were produced by Nouveau Monde’s advanced international technical team, in partnership with its R&D consortium partners, and have now delivered to prospective lithium-ion battery customers for qualification testing.
  • This proprietary carbon coating technology will be incorporated into the Company’s demonstration plant at Becancour, Quebec.
  • Nouveau Monde is actively working with its partner, Forge Nano, to even further enhance the performance with their Atomic Layer Deposition ALD technology.
  • Nouveau Monde’s ability to control the entire value chain from graphite ore to the final coated anode material allows it to offer a high-quality and consistent product, representing an important and cost-competitive supply of non-Chinese sustainable anode product to the fast-growing lithium-ion battery market.
  • Nouveau Monde’s unique, high-quality and zero-carbon footprint anode materials are well placed to serve both the North American as well as European anode materials markets for decades to come.

MONTREAL, QUEBEC, November 12, 2020 –  Nouveau Monde Graphite (“Nouveau Monde” or the “Company”) (TSXV: NOUOTCQX: NMGRFFrankfurt: NM9) is pleased to announce that it has completed an important technical program on its proprietary coating process with its research and development consortium, internal experts and raw material suppliers. The primary objective of the program, operating since 2018, was to establish the optimal process operational parameters and design criteria needed to complete the engineering and procurement of a large-scale demonstration coating line. This process step is crucial in demonstrating the full value chain proposition as an integrated battery anode materials producer, from mine to market-ready coated spherical purified graphite (“CSPG”).

Eric Desaulniers, President & CEO, states, “The last few years of dedication to R&D and to forging partnerships with the leading research and battery anode experts is now allowing us to bring to market a high-quality ready-for-market battery anode material that compares very favorably with the established Asian supply chain. We will be able to respond to clients needs based on scale, cost-competitiveness, carbon-neutrality and product quality and performance efficiency.”

Furthermore, Arne H.Frandsen, Chairman of Nouveau Monde, commented: “This is an important announcement, confirming both the high quality of our anode product as well as our ability to produce those critical battery raw materials. With our substantial resource base in Québec and integrated value-chain, Nouveau Monde is well set to become a global leader in the supply of anode materials for decades to come”.

To confirm product quality and performance, the Company’s CSPG was benchmarked against the leading Asian commercial anode material that currently dominate the lithium-ion supply chain. A series of electrochemical tests made by the National Research Council of Canada revealed that under the same conditions in half-button cell batteries, the reversible capacity (a measure of the energy density for performance) obtained with Nouveau Monde’s anode material is 365 mAh/g compared with 360 mAh/g for the leading Asian standards. Importantly, the coulombic efficiency for the first cycle was similar for both products and within industry specifications. Further, the broader market minimum specification for reversible capacity is well below at only 350 mAh/g, highlighting the market opportunity for Nouveau Monde.

The importance of coating to Nouveau Monde

In a lithium-ion battery, coating is used to:

  • form a stable and passive carbon barrier around the high-purity spheronised graphite, which prevents the electrolyte from penetrating into the graphite and creates a stable electrolyte interface layer; and
  • increase first-cycle efficiency by decreasing the specific surface area of the particles, reducing the loss of lithium within the electrolyte interface.

Coating is considered the last value-added production step and will allow Nouveau Monde to provide high purity, battery grade anode material for the rapidly growing electric vehicle and renewable energy storage industries, securing significantly higher margins and cash flow for shareholders.
