Submission reinforces Grafoid's status as an industry-leading R&D Company that produces economically scalable graphene for use in development applications by leading corporations and institutions worldwide.

KINGSTON, ON / ACCESSWIRE / March 1, 2021 / Grafoid Inc. ("GRAFOID") and Focus Graphite Inc. (TSXV:FMS) (the "Company" or "Focus Graphite"), jointly announced today the submission of a Provisional Patent Application titled: "Advanced Anode Material Comprising Spheroidal Silicon Enhanced Graphite Particles And Process For Making Same". The present invention pertains to the field of electrode materials and in particular to processes for making materials for use as a new generation of lithium-ion battery anode material.

Due to the limitations of using silicon alone in battery anodes, adding silicon (Si) to graphite to increase the theoretical capacity limit in lithium-ion batteries has been gaining intellectual traction. There remains a need for a highly controllable process for the efficient incorporation of silicon into a graphite matrix to provide spheroidal Si-enhanced graphite particles that are suitable for use as advanced anode materials.

"The submission of this important provisional patent application is validation of Grafoid's and Focus Graphite's commitment to innovation and represents an important industry milestone," said Dr. Joseph Doninger, Director of Technology and Manufacturing at Focus Graphite. "We are very proud of this important milestone and the future product benefits that will be derived from this new lithium-ion battery anode material, in particular to the manufacturers of electric vehicles for increasing battery life and power."

For anode material to be considered battery-worthy, practical active material loadings on the anode should be on the order of 10 to 12 mg/cm2 (or higher). In an embodiment of the invention, the anodes comprised of silicon-enhanced spheroidal graphite have active material loadings falling in the range from 6.2 to 16.2 mg/cm2. The formation of spheroidal particles is beneficial to provide maximum packing density in the formation of the lithium ion battery anode materials, which will maximize both the Specific Energy (Wh/kg) and Energy Density (Wh/L) of a full battery cell level.
