Saint Jean Carbon Files Patent for Carbon Coating Lithium-ion Battery Grade Graphite
OAKVILLE, ONTARIO--(Marketwired - Dec 1, 2015) - Saint Jean Carbon Inc. ("Saint Jean" or the "Company") (TSX VENTURE:SJL), a carbon science company engaged in the development of natural graphite properties and related carbon products, is pleased to announce the filing of a patent for the carbon coating of spherical graphite that is used in lithium-ion batteries. This is an essential step in the entire process for creating spherical shaped graphite. First, the concentrate graphite is jet milled to approximately 2 microns larger than the desired final size material; as an example - 15 microns. Next, the material is purified to typically 98.9% gc. The material needs to be spherical shaped like a potato, dried, carbon coated and finalized with a material that has a tap density of 1%. The individuals currently employed by the Company have several years of experience and has spent many years working through this process and the final push with our industry and academic partners has helped greatly in making it a reality.
The reason that carbon coating spherical shaped graphite is to be used in lithium-ion batteries is that the graphite needs to have a sensitivity to propylene carbonate (PC) - based electrodes. PC is an essential solvent for the electrolytes of lithium-ion batteries. The carbon coating (>1wt%) keeps the graphite surface from having direct contact with the electrolyte. Today, there are a number of ways to coat the material. Popular ways include thermal vapour decomposition (TVD) and chemical vapour disposition (CVD). Our system is a continuous feed from the spherical shaping system into the drying (moisture removal) chamber where the pre sized material flows into a vacuum chamber. Once the moisture has been completely removed, the material is forced with air pressure into the high-pressure vessel. The vessels are lined with electromagnetic bars that create enough force to keep the graphite in colloidal suspension. A very small electrical charge is applied to the material. The material is introduced to the diamagnetic carbon through the feed port and blends with the oxygen. The carbon repels the magnetic field and is attracted to the graphite, dispersing onto the mildly charged graphite, creating a nano level coating. The material on a continuous feed enters the cooling chamber, and then through to the output holding chamber. See diagram below.

Paul Ogilvie, CEO, commented: "Having now created an end-to-end solution which marks a great milestone for Saint Jean. We believe we can be more competitive, cost effective and most of all work towards supply agreements with North American battery manufacturers. Presently, our proposed engineering model with our industry partners is to build the entire process at the location of the battery manufacturing facility to assure quality control and seamless integration with the assembly line."
The next steps in the process are: a number of add-on patents to be filed in the coming weeks, the secondary tests from Western University on our ferromagnetic graphene, and our industry partners' projects which are all moving along well. We continually test our raw materials for improvement in overall performance.
