Graphene nanoplatelets used to make battery anode with four times the capacity available now at commercial scale

XG Sciences has launched a new generation of anode materials for lithium-ion batteries (LIB) with four times the capacity of conventional anodes. The new anode material is produced through proprietary manufacturing processes and uses the Company’s xGnP® graphene nanoplatelets to stabilize silicon particles in a nano-engineered composite structure. The material displays dramatically improved charge storage capacity with good cycle life and high efficiencies.

The graphene battery anodes are available immediately at commercial scale.

The exact performance of the new anode materials will depend on the specific battery formulations used by the cell manufacturer, noting that XGS has demonstrated capacity of 1500 mAh/g with low irreversible capacity loss and stable cycling performance in life tests.

Mike Knox, the XGS CEO, said that “in keeping with our focus on developing cutting-edge science for commercial applications, we engineered the nano-materials and processes to produce anode materials that are available today at commercially attractive prices.”

“As the world’s largest producer of graphene nanoplatelets, we have the capacity and production expertise to produce battery materials efficiently and effectively, and we have global production partners. For example, two of our strategic partners, POSCO and Hanwha Chemical, already manufacture electrode materials for lithium-ion batteries. One of our licensees, Cabot Corporation, recently introduced their first battery additive based on our technology. We are also proud to work with such diverse development partners such as Georgia Tech, several large battery manufacturers, and several of the US National Laboratories.”
