[{"type":"text","content":" Vancouver, March 02, 2023 (GLOBE NEWSWIRE) -- Ceylon Graphite Corp (“Ceylon Graphite”) (TSX-V: CYL) (OTC: CYLYF) (FSE: CCY) is pleased to announce that it has completed the world’s first full cell testing using spherodized vein graphite materials in commercial size pouch cells following automotive “Original Equipment Manufacturer” (OEM) standards. Ceylon Graphite’s vein graphite anode material exceeded comparable anodes made with industry standard commercial synthetic graphite and were able to achieve excellent reproducibility in the tests carried out from 2021 through to 2023. This is the first time that spherodized vein graphite materials were tested in a lithium-ion battery full cell. The tests were conducted at a leading global, independent test facility, Warwick Manufacturing Group (WMG), part of University of Warwick’s Energy Innovation Centre. A summary of the test results, completed in February 2023 is highlighted below. Repetitive testing of Ceylon Graphite’s unique natural vein graphite material has achieved reproducible outstanding performance results compared to industry standard synthetic graphite: Discharge capacity of 161 mAh/g, as compared to the published industry standard of 153 mAh/g Small loss in capacity over 120 cycles We believe that the impressive performance of our vein graphite material is due to: High crystallinity of vein graphite originated highest C% in nature (above 90%) In-house purification technology (pending patent) without using any HF (Hydro fluoric) acids Ceylon Graphite proprietary spherodizing and formulation technology Ceylon Graphite has a mine to battery strategy that will maximize the value of our high-grade Sri Lankan vein graphite by transforming it into anode graphite for the rapidly growing lithium-ion battery market. These results provide us the opportunity to: Collaborate with potential customers looking for sustainable high-quality anode materials Position Ceylon Graphite in the Li-Anode graphite market and achieve potential near term sales Our latest results for the Full Cells: The cells were tested in a full cell system at a rate of C/5, meaning 5 hours to charge and 5 hours to discharge. Extended cycling exhibited reversible charge/discharge behaviour with less than 15% overall capacity loss over 120 cycles. The C/5 stable cycling gives an average reversible capacity of 161 ...
