Saint Jean Carbon Files Patent for Carbon Coating Spherical Graphite

Saint Jean Carbon Inc. (TSXV:SJL) announced that it’s filed a patent for the carbon coating of spherical graphite used in lithium-ion batteries.
As quoted in the press release:

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.

Paul Ogilvie, CEO of Saint Jean, 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.
