GraphPure™
Cost Effective + Environmentally Friendly + Sustainable = Game Changing
GraphPure™
Technology Overview
Unique Purification Process
A holistic approach that considers the processing cost, environmental impact and operational flexibility
Sequence Flexibility
GraphPure™ can treat graphite independent of particle size and shape, which provides significant opportunity to optimize the sequencing of unit operations.
Operating Conditions
Operating conditions are tailored for each NFG source based on specific impurity make-up
Reagent Regeneration
The processing reagents are cost-effectively recycled in-situ
Renewable Energy
No fossil fuels required and zero carbon footprint possible
Battery-Grade Graphite Confirmed
Demonstrated (>99.95% purity) at pilot scale on multiple graphite types. Anode performance on par with reference in LFP and NMC batteries.
At A Glance
Our Integrated Technology Package
At the heart of our Integrated Technology Package is the GraphPure™ purification technology. Our technology removes the key technical bottleneck inhibiting growth of the non-Chinese LiB-grade NFG graphite market.
However, to meet LiB-grade graphite specification, the NFG must also be appropriately sized and shaped (termed micronized and spheronized) and coated with amorphous carbon.
GGT will supply the option for a fully Integrated Technology Package that will include micronization and spheronization equipment from existing suppliers and carbon coating from its partner Rain Carbon with GraphPure™.
The Integrated Technology Package will provide GGT’s clients with a complete solution to transform NFG into LiB-grade graphite.

The Status Of
GraphPure™ Technology
We have successfully demonstrated GraphPure™ at the bench and pilot scale. The key technical and cost drivers have been identified and a techno-economic model developed, which is used to underpin the technology development and commercialization strategy.
