The testing was conducted using "Lithium/graphite battery test cells", which is right up Panacis alley...
The spherical graphite has been evaluated in Lithium/graphite battery test cells and the performance of these cells demonstrated that it meets or exceeds current commercial performance requirements and that Bissett Creek graphite does not contain any impurities that negatively affect cell performance. Further test cycles are on-going. The cells were made and testing carried out in a highly qualified, independent laboratory.
