[{"type":"text","content":" VANCOUVER, British Columbia, Feb. 26, 2020 (GLOBE NEWSWIRE) -- Ceylon Graphite Corp. (“Ceylon Graphite” or the “Company”) (TSX-V: CYL) (OTC: CYLYF) (FSE: CCY) is very pleased to announce excellent results of Spheronization test work carried out at an independent facility with vein graphite from our K1 mine. All analyzed parameters of the manufactured spherical graphite product are in the range of typical comparable products. SEM images display well rounded spherical graphite particles similar to products on the market. Spheronization is a sizing and shaping process that micronizes and rounds the vein graphite particles. Spheronization is done to optimize the particle surface area to achieve the highest performance in the anode. The Scanning Electron Microscopy (SEM) picture below shows smooth, spherical particles. This is significant as presently all-natural spherical graphite is produced from flake graphite. Ceylon has not yet undertaken electrochemical characterization of our vein graphite, however published papers indicate that vein graphite exhibits “many favourable characteristics such as high reversible capacity… Among the natural graphite varieties, vein graphite typically possesses very high crystallinity together with high natural purity, which in turn reduces the cost of purification.” Half-cell testing was carried out with vein graphite and “Galvanostatic charge-discharge, cycle voltammetry, and impedance analysis revealed a high and stable reversible capacity of 378 mAh/g, which is higher than the theoretical capacity of flake graphite at 372 mAh/g”. The study also observed low irreversible capacity acquiesces to high columbic efficiency of over 99.9%. The study concluded that “highly crystalline developed natural vein graphite can be presented as a readily usable low-cost anode material for Li-ion rechargeable batteries.” Ceylon Graphite also announces that Robert Marvin has resigned as a Director of the company. Donald Baxter, P.Eng., Director of Ceylon Graphite Corp., is the new Qualified Person as defined by National Instrument 43-101 (\"N.I. 43-101\") guidelines.
