[{"type":"text","content":"OTTAWA, Sept. 28, 2017 (GLOBE NEWSWIRE) -- Focus Graphite Inc. (TSX-V:FMS) (OTCQX:FCSMF) (FSE:FKC) (“Focus” or the “Company”) is pleased to announce excellent results from ongoing independent laboratory tests comparing long term cycling performance of Lac Knife surface coated spherical crystalline fine flake graphite against commercially competitive standard grades of coated crystalline flake graphite in the anodes of CR2016 coin cells. The results presented are a follow up from data presented in Focus’ November 25, 2015 news release where similar tests were run on Lac Knife’ standard grade spherical graphite. Those tests exhibited essentially zero loss in capacity after 110 cycles versus two commercially competitive grades that showed losses of 4.4% and 6.4% over the same number of cycles. Testing was conducted at a globally recognized laboratory in Europe. The name of the laboratory is being withheld because of commercial and competitive confidentiality. Ongoing Life Cycle Testing On November 25, 2015 Focus Graphite published data showing that its Lac Knife Standard Grade of uncoated and coated spherical graphite exhibited essentially zero loss in capacity after 110 cycles versus two commercially competitive grades that showed losses of 4.4% and 6.4% over the same number of cycles. In a presentation to the International Battery Seminar in Fort Lauderdale, Florida on March 26, 2017, Dr. Joseph Doninger, Focus’ Director of Manufacturing and Technology presented long term cycling test results showing that the zero loss in capacity of the Standard Grade of coated spherical graphite lasted for 250 cycles and showed a loss of only 4.5% in capacity after 570 cycles compared with losses of 11.7% after 440 cycles and 10.5% after 510 cycles for a competitive supplier’s coated spherical graphite. He said that projecting these results suggests that Lac Knife’s coated SPG could last beyond 2000 cycles in full sized batteries. “A good rule of thumb to use in comparing the long term cycling performance of different graphites in Lithium Ion batteries is determining how many cycles a battery will last before losing 20% of its capacity,” Dr. Doninger said. 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 c...
