Sarytogan Graphite Ltd (ASX:SGA) managing director Sean Gregory joins Proactive’s Jonathan Jackson after the company reported high performance for lithium-ion batteries utilising anodes of Coated Spherical Purified Graphite (CSPG) from Sarytogan Graphite. Coin-cell batteries made from CSPG have now cycled 100 times, demonstrating a significant improvement in performance due to the coating process. This enhancement has increased market pricing from approximately US$2,500 to US$8,000 per tonne. Gregory expressed satisfaction with the results, highlighting the premium pricing potential and the opportunity for direct relationships with battery manufacturers and OEMs. The coating process, which smooths the surface of the spherical graphite and reduces surface area, has now been incorporated into the pre-feasibility study, which is on track for completion by September 2024. Previously, Sarytogan reported superior battery performance using Uncoated Spherical Purified Graphite (USPG), with a reversible capacity of 342-347 mAh/g. The recent tests with CSPG showed an irreversible capacity loss (ICL) of 11%, close to the industry benchmark of 10%, and a reversible capacity of 354 mAh/g. The batteries retained 98.9% capacity after 100 cycles, suggesting over 1,600 cycles before reaching 80% capacity, a notable result for high-performance lithium-ion batteries.
