XG Sciences and Graphene Nanoplatelets

In previous articles, we highlighted the current investment potential of graphene and looked at companies such as Applied Graphene Materials (LON:AGM) which has risen 90% since their November 2013 IPO. Another privately held company involved in graphene production with impressive partnerships and a broad customer base is XG Sciences.

About XG Sciences

Founded in 2006, Michigan based XG Sciences claims to be a world leader and first-to-market with their production of low cost, high volume graphene nanoplatelets. Investors in XG Sciences include Hanwha Chemical, POSCO, and most recently Samsung Ventures. Cabot Corporation is also a non-exclusive licensee of their production processes and a development partner. XG Sciences was spun-off from Michigan State University from which XGS has licensed a portfolio of existing intellectual property. With 30 employees, the company has a 10,000 square foot R&D facility and a 20,000 square foot manufacturing facility. This $8 million manufacturing facility can produce 80 tons per year of graphene nanoplatelets at a cost of $40 – $50 kg for tonnage quantities. XG Sciences has 550+ customers in 32 different countries which include the likes of Boeing, Lockheed, Honda, 3M, and General Motors.

What are Graphene Nanoplatelets?

Graphene nanoplatelets are particles consisting of multiple layers of graphene. They represent a new class of carbon nanoparticles with multifunctional properties. xGnP® brand graphene nanoplatelets have a very thin but wide aspect ratio as seen below:

This unique size and shape makes these particles especially effective at providing barrier properties, while their pure graphite composition makes them excellent electrical and thermal conductors. The applications for these particles are many, and include composites, EMI shielding, inks, coatings, and electrodes. In April of last year, XG Sciences announced the launch of a new generation of anode materials for lithium-ion batteries with four times the capacity of conventional anodes. As a vote of confidence, late last year XG Sciences was awarded $1 million in funding from the U.S. Department of Energy (DOE) for continued development of its XG SiG™ high-energy lithium-ion battery materials. XG Sciences has a notable customer base, strong partnerships, production capacity, and is, more importantly, demonstrating viable commercial applications for their new graphene nanomaterial. Low cost, high volume production will help accelerate the commercial adoption of graphene nanoplatelets and XG Sciences is a company to watch closely as the graphene story unfolds.

    It would be great to see these graphene claims backed up with XRD often these materials are subjected to sonication and acid reflex as a consequence the outputs are related more closely to amorphous carbon due to the loss of crystallinity . OK a lot of researchers will try a few grams of these materials but end up disappointed as grain boundaries and defects handicap their potential and give elevated BET surface numbers as the defects and holes in what is basically nano graphite elevate the BET surface area figures.

    Thank you for the comments David. It would be good to know then how many of those 550+ customers are recurring.
