Ann: BKT achieves industry leading spheronising graphite yields, page-3

*  Finally, we have had exceptional feedback from end users from the announced 130-cycle battery cell results that confirmed our graphite has the potential to enable battery manufacturers to produce more stable lithium-ion batteries (LIBs), at a lower cost with a longer cycle life.

* higher purity 99% TGC concentrates were provided to Dorfner Azaplan for spheronising and chemical purification trials

* The flake concentrates delivered an optimised 60% spheronising yield – almost double the yield of current spheronising operations. This excellent result indicates significant cost savings that could be achieved by using Mahenge graphite as a feed stock

* Achieving 99.95% purity was easily achieved with low doses of two different acid compositions in tests C7 and C9. Acid purification of a 99% high purity spherical consumes much less acid than a low purity 95% concentrate. This offers spheronisers using Mahenge graphite cost savings in purification through time and reagent savings.

* Chemical purification trials exceeded the 99.95% TGC purity levels demanded by battery producers and demonstrated significant reductions in chemical consumption and processing time. This is attributable to the high initial purity of the precursor Mahenge flake.

* Importantly the shape, specific surface area (BET) and tap densities of the SPG exceed battery maker specifications.
