Renascor Achieves Battery-Grade Graphite Production
Key points
- Renascor produced battery-grade purified spherical graphite at 99.97% purity
- Demonstrates the HF-free purification process at demonstration scale
- Supports ongoing discussions with offtake and strategic partners
Full summary
Renascor Resources has produced battery-grade purified spherical graphite (PSG) at its demonstration plant in Adelaide, South Australia, achieving a purity of 99.97% carbon. This milestone validates the scale-up of Renascor's hydrofluoric acid (HF)-free purification process. The company has used third-party graphite in initial batch trials, with plans to use its own Siviour graphite in future trials. This achievement supports Renascor's ongoing discussions with potential offtake and strategic partners and positions the company as a competitive ex-China source of battery-grade PSG.
Guidance
Renascor estimates operating costs of approximately US$459 per tonne for its purification process.
Outlook
Renascor plans to continue batch trials using both third-party and Siviour graphite to optimize the process and produce samples for prospective customers. The company also aims to progress to multi-tonne trials to assess long-term performance and generate further data for commercial plant design.
