XG Sciences (XGS), a leading provider of graphene nanoplatelets, has demonstrated full battery cell cycle stability through more than 400 charge/discharge cycles with a charge storage capacity of 600 mAh/gram over a broad voltage window in its next generation silicon graphene (earlier post) (XG SiG) anode materials for lithium-ion batteries.
“We believe our latest material is the first commercially viable silicon and graphene based anode formulation to achieve this all important performance threshold. With charge storage capacity of up to 4 times today’s typical anodes, first cycle efficiency of 85-90%, low swelling and life that is more than double our previous generation, we believe this material will open many new markets for our customers with an affordable and safe anode formulation,” said Dr. Philip Rose, XGS CEO.

XGS produces the anode material through proprietary manufacturing processes and uses its xGnP graphene nanoplatelets to stabilize silicon particles in a nano-engineered composite structure.
Robert Privette, XG Sciences’ Vice President of Energy Markets, said that XGS is working with battery manufacturers globally to incorporate XG SiG anodes and xGnP graphene conductive additives into their products. Multiple battery formats and multiple battery design capacities are under test.
We foresee a wide range of applicable battery applications in any market where energy storage is a high priority—like handheld electronics, automotive, and industrial energy storage.—Rob Privette
In January 2014, Samsung Ventures invested in XGS. (Earlier post.)
XG Sciences is presenting in three upcoming industry conferences:
a presentation at the 32nd International Battery Seminar & Exhibition (9-12 March) in Fort Lauderdale, FL;
a presentation at the 2015 Next Generation Batteries Conference (21-22 April) in San Diego, CA; and
a poster at the US Department of Energy (DOE) Annual Merit Review Meeting (8-11 June) in Washington, DC.
XG Sciences is also partnering with Shmuel De-Leon and Prof. Doron Aurbach (Bar Ilan University) for a 3-day technical seminar on batteries, supercapacitors, fuel cells and electric vehicles. The three-day seminar will provide participants from all levels of the commercial supply chain as well as academic researchers with the opportunity to address the latest technologies and application requirements. XG Sciences will host the event at its Lansing, MI offices on 6-8 July.
