Coin cell tests on Focus Graphite Inc. (TSXV:FMS,OTCQX:FCSMF,FWB:FKC) Lac Knife Spherical Graphite yielded positive results: premium medium and fine grades exceed the performance of benchmark commercially available grades by significant percentages, and confirmed Focus’ capability to tailor lithium ion battery anode grade graphite and value added products to meet the most stringent customer specifications. Highlights:
  • Lac Knife SPG battery tests evaluate three proprietary formulations that responded very well to CR2016 coin cell performance testing
  • Large, medium and fine micron size produced outstanding performance metrics
  • Testing results on the premium medium and fine grades exceed the performance of benchmark commercially available grades by significant percentages.
  • Tests confirm Focus’ capability to tailor lithium ion battery anode grade graphite and value added products to meet the most stringent customer specifications
As quoted in the press release:
Two premium (medium and fine) grade SPG’s developed by Focus have achieved First Cycle Irreversible Capacity Losses of 1.44% and 1.01%, respectively, truly remarkable results. These lower ICL values of the SPG grades produced by Focus can lead to the production of higher capacity and longer life Li Ion batteries. Furthermore, the low surface areas of the premium coated grades of SPG at 0.48 and 1.14% m2/g can help to improve the safety of Li Ion batteries. The use of higher surface area carbons in these batteries can cause the temperature of the battery to increase and possibly result in the occurrence of thermal runaways.
