OTTAWA, CANADA – Focus Graphite Advanced Materials, a company specializing in high-grade flake graphite and advanced graphite materials, has received notification that the Canadian Intellectual Property Office has allowed its patent application for innovative battery anode materials.
Patent Covers Silicon-Enhanced Graphite Technology
The granted patent, designated No. 3,209,696, is titled “Advanced Anode Materials Comprising Spheroidal Additive-Enhanced Graphite Particles and Process for Making Same.” This patent specifically protects proprietary processes and compositions for creating silicon-enhanced, spheroidal graphite particles. According to Focus Graphite, these materials are engineered to significantly boost critical performance metrics for lithium-ion battery anodes, including energy density, charging efficiency, and cycling stability.
The technology integrates silicon directly within the graphite particle structure. This approach aims to overcome key challenges faced by silicon-enhanced anodes, namely the volume expansion that occurs during charging cycles and the instability of the solid electrolyte interphase (SEI). By embedding silicon within the graphite matrix, the material is expected to better accommodate volumetric changes, thereby improving mechanical integrity. Furthermore, the surrounding graphite structure is designed to limit direct interactions between silicon and the electrolyte, a factor that contributes to enhanced cycling stability and extended battery lifespan.
Canadian Intellectual Property Office Confirms Novelty and Inventiveness
The Canadian Intellectual Property Office has concluded its examination, confirming that the patent claims meet all established Canadian requirements for patentability, including novelty and inventiveness. The patent is anticipated to be formally granted upon completion of the final administrative procedures.
Focus Graphite CEO Welcomes Patent Allowance
Dean Hanisch, Chief Executive Officer of Focus Graphite, expressed satisfaction with the patent allowance, stating, “The allowance of this Patent represents the culmination of years of focused research and development. The underlying technology was shaped under the guidance of Dr. Joseph Doninger, whose deep technical insight and commitment to innovation were instrumental to its success, and we are grateful for the work he contributed.”
Hanisch added, “With the Patent now allowed, we are well positioned to move forward with broader testing and advancement of this technology as part of our downstream strategy.”
This development marks a significant step for Focus Graphite as it progresses with its advanced materials strategy within the electric vehicle battery sector.
