Wildcat Discovery Technologies Evaluates Graphene Nanoplatelets for XG Sciences, Inc.

Wildcat measures effect of three new graphene conductive additives on lithium-ion battery performance.

San Diego, CA, June 03, 2010 --( Wildcat Discovery Technologies, a technology company using combinatorial methods to rapidly synthesize and evaluate new battery materials, has completed a project for XG Sciences. Wildcat evaluated three versions of XG Sciences’ xGnP® brand graphene nanoplatelets as conductive additives for Lithium-ion battery electrodes, and also evaluated the effect of two nanotube materials and a carbon black.

Completed in less than a week, the project involved the formulation of LiFePO4 electrodes with and without XG Sciences’ graphene additives. Wildcat synthesized LiFePO4 using three versions of XG’s xGnP graphene materials, assembled the electrode material into cells and then evaluated them at five different charge/discharge rates. The performance of these cells was compared to LiFePO4 cells formulated with nanotubes and standard carbon black.

Two of XG’s graphene materials increased cell capacity by as much as 3% at rates near 1C vs. carbon black, but neither material was optimized during the study. XG Sciences is now planning a larger effort to optimize the material for energy storage applications. “Wildcat completed this work in a fraction of the time it would have taken us via other methods,” said Mike Knox, XG Sciences CEO. “We’re quite excited about the potential of our xGnP® brand materials based on these initial results.”
