Wildcat Discovery Technologies Evaluates Graphene Nanoplatelets 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.”

Wildcat Discovery Technologies is engaged in the discovery and sale of specialty materials for clean tech energy applications; particularly batteries. Utilizing combinatorial chemistry pioneered in the life sciences field, Wildcat has developed proprietary high throughput synthesis and testing workflows for the rapid exploration of new battery materials.

This technology enables Wildcat scientists to synthesize and evaluate thousands of materials in the time it takes most labs to evaluate only a handful.

XG Sciences, Inc. is a privately held corporation serving customers around the world. XG Sciences manufactures a variety of grades and sizes of its xGnP® brand graphene nanoplatelets for applications ranging from nano-composites to energy storage.

Its proprietary manufacturing methods allow it to produce an exceptionally pure form of graphene nanoplatelets in sizes of up to 25 microns or larger.
