Focus Graphite Reports Zero Loss in Lithium-Ion Battery Capacity in Long-term Cycling Performance Testing

Focus Graphite Inc. (TSXV:FMS,OTCQX:FCSMF,FWB:FKC) announced excellent results from independent laboratory tests conducted to compare the long term cycling performance of Lac Knife surface coated spherical crystalline fine flake graphite with two commercial grades of coated crystalline flake graphite in the anodes of CR2016 coin cells.
As quoted in the press release:

The results presented are a follow up from data presented in Focus’ February 26, 2015 news release where similar tests were run on “as-is” minus 200 mesh fines of Lac Knife graphite which also showed to have excellent long term cycling performance.
Testing was conducted at a globally recognized laboratory in Europe. The name of the laboratory is being withheld because of commercial and competitive confidentiality.
Highlights:

• Coin cell tests run on purified uncoated and coated standard grades of Lac Knife spherical graphite (SPG) showed that both grades exhibited essentially no loss in capacity up to the limit of the tests of 110 cycles
• Coin cell tests run under the same formulation and conditions showed that the two commercial grades of coated flake graphite exhibited capacity losses of 4.35% and 6.43% up to the limit of the tests of 110 cycles.

Focus Graphite is the sole owner of the high purity Lac Knife natural flake graphite project in the Côte-Nord region of northeastern Québec.
The Company’s aim is to become one of the lowest cost producers of high-purity technology graphite. The purpose of its ongoing battery materials testing efforts is to validate the commercial viability of the high purity crystalline flake graphite recovered from its Lac Knife deposit, and to demonstrate that Lac Knife graphite holds the potential to improve the performance of anodes in Lithium Ion batteries.
The properties of the flake graphite recovered from the Lac Knife high quality and high carbon content graphite deposit, allow for the recovery of concentrate that grades 98% C even in the finer size fractions down to 200 mesh (75 microns) that are usually the most difficult products to sell. This holds the potential for Focus to create a high-margin business opportunity by providing customers with a finer grade, lower cost, value-added graphite product.

Focus Graphite Director of Manufacturing and Technology, Dr. Joseph E. Doninger, stated:

Of particular note is that these new results showing that the Lac Knife graphite exhibits excellent long-term stability, adds to the results reported in our February 2015 news release. That previous data presented Lac Knife’s graphite as exhibiting very high reversible capacities and very low first cycle capacity losses. Combined, these improved properties would make Lac Knife graphite an excellent replacement for both the synthetic and natural flake graphites currently being used in the manufacture of Lithium-Ion batteries.
