International Graphite (ASX: $IG6) Announcement Overview

International Graphite Limited (ASX: $IG6) has announced exceptional results from purification and electrochemical testwork on graphite concentrates from the Company's Springdale Graphite Project in Western Australia. The purification testwork on micronised and spheroidised Springdale concentrates exceeded the purity requirements of major lithium-ion (Li-ion) batteries, achieving results ranging from 99.96% LOI to 99.97% LOI. Additionally, electrochemical tests on an uncoated purified sample of Springdale graphite concentrate showed exceptional battery charging and discharging capacity.

Executive Commentary on Test Results

International Graphite Technical Director David Pass expressed satisfaction with the results, stating, 'The purification results demonstrate the potential for an optimised and simplified purification process to be used as an alternative to the traditional industry standard HF method. The electrochemical results are highly encouraging as a first phase sighter test program. These results will inform the optimisation of micronisation, spheroidisation, and purification testwork and flowsheet development for our planned battery anode facilities.'

Summary of International Graphite Announcement

International Graphite (ASX: $IG6) has achieved exceptional battery test results, surpassing the purity requirements of major lithium-ion batteries. The purification testwork on Springdale concentrates yielded impressive results ranging from 99.96% LOI to 99.97% LOI, exceeding the industry standard purity grade of 99.95%. The electrochemical tests demonstrated near theoretical-specific capacity for a graphite anode in Li-ion batteries of 372 mAh/g, indicating high stability and durability. The company plans to further optimize these results and conduct stress testing over longer cycles. International Graphite's Technical Director, David Pass, highlighted the potential for an alternative purification process and the promising nature of the electrochemical results, which will guide the development of their planned battery anode facilities.
