SRG’s Graphite Demonstrates Excellent Electrochemical Characteristics

SRG Graphite (TSX-V:SRG) (“SRG” or the “Company”) today announced the results of electrochemical characterization of its spherical purified graphite (“SPG”) material produced from the Company’s Lola graphite deposit in the Republic of Guinea. The characterization tests were performed by Dorfner ANZAPLAN (“ANZAPLAN”) at their facility in Hirschau, Germany.
ANZAPLAN tested and reported on three main electrochemical characteristics of SRG’s SPG, important for the lithium-ion battery market: cyclic voltammetry which measures kinetics and hysteresis of the charge/discharge cycle, specific capacity and cycling performance.

ANZAPLAN Report: SRG’s Spherical Graphite Electrochemical Characterization Highlights

• Cyclovoltammetric measurements indicate that the kinetics of SRG’s purified spherical graphite makes it suitable as active material in lithium ion batteries
• Achieves remarkable reversible capacities of >365 mAh/g, which is very close to the theoretical maximum of 372 mAh/g
• Demonstrates above average cyclability, achieving a value of 356 mAh/g after 100 cycles at a cycle rate of 0.5C. This represents ~99% of initial capacity and 96% of theoretical capacity, which is better than the average value for typical uncoated spherical graphite products.
