Ceylan Graphite succeeds in producing high performance

Out Performs Leading Commercial Producers:

Average initial capacity of 435 mAh / g – Average reversible capacity of 382 mAh / g

VANCOUVER, British Columbia, September 27, 2021 (GLOBE NEWSWIRE) – Ceylan Graphite Corp. (“Ceylon Graphite”) (TSX-V: CYL) (OTC: CYLYF) (FSE: CCY) is pleased to announce that it has achieved a significant breakthrough in the performance of its vein graphite anode material (C 99.995%) in the cell part for the lithium-ion (“Li-ion”) battery market. When tested at a leading independent global facility, WMG, which is part of the Energy Innovation Center at the University of Warwick, the material of the Ceylon venous graphite anodes far exceeded comparable anodes manufactured. with standard commercial synthetic graphite. This is the first time in the history of battery research that commercial spherodized venous graphite materials are tested in a lithium-ion battery in a button cell.

The results gave a reversible capacity (RC) of 382 mAh / g, which is beyond what is expected for the best synthetic graphite currently in commercial use with an RC of 363 mAh / g. Data was collected from 5 separate button cells for Ceylon graphite and for materials from commercial synthetic suppliers. The galvanostatic graphs below illustrate these results:

The stable C / 5 cycle gave an average reversible capacity of 353 mAh / g with a standard deviation of 9 mAh / g over 25 cycles compared to the synthetic supplier 307 mAh / g. The batteries are tested at a rate of C / 5, which means 5 hours to charge and 5 hours to discharge, achieving approximately 2+ full cycles per day

The exceptional performance of Ceylon vein graphite over synthetic graphite currently in commercial use is due to the high crystallinity of Sri Lanka vein graphite. The first results prove the suitability of our material for lithium-ion battery anodes for autonomous or possible mixing with synthetic graphite.

Ceylon CEO Don Baxter said: “I expected very good results from our first battery tests, but I was delighted to see that my expectations were far exceeded by our graphite vein. These results constitute a very significant development for Ceylon. The unique characteristics of our Sri Lankan venous graphite combined with our proprietary processing technologies produce a Li-ion battery with significantly higher power and energy as tested by WMG. The Company believes that based on the results, Ceylon Graphite will set a new industry standard. In addition, we believe that the end-to-end power consumption of the process of producing battery grade anode material from vein graphite is the lowest, compared to synthetic and flake graphite, due to the fact that the Sri Lankan graphite does not require primary treatment. , due to the high in situ content greater than 90% Cg. “

The test results and Ceylon’s unique position in the market create opportunities for large-scale development, business partnerships and sales of advanced materials. Ceylon’s significant resource positions and our energy products division (Ceylon Graphite Technologies (UK)) will enable the Company to become a stand-alone battery technology company, with exclusive access to a unique and high-grade battery grade graphite. lower cost performance of our wholly-owned deposits in Sri Lanka.
