Giyani Metals Advances to Phase 2 of C4V’s Battery Qualification After Successful High-Purity Manganese Testing
Battery-grade manganese producer Giyani Metals Corp has announced that its high-purity manganese oxide (HPMO), produced at the company’s Johannesburg demonstration plant, has successfully met Phase 1 qualification standards set by US-based battery technology firm Charge CCCV (C4V).
The achievement allows Giyani’s HPMO to progress to Phase 2 of C4V’s Digital DNA Supply Chain Qualification Program, marking a key milestone in the company’s path toward commercial offtake agreements.
Qualification Success Highlights Giyani’s Progress
Giyani, the developer of the K.Hill battery-grade manganese project in Botswana, has created a proprietary hydrometallurgical process to produce high-purity manganese for use in electric vehicle (EV) and energy storage system (ESS) cathode materials.
Unlike laboratory-scale samples, the HPMO tested by C4V was produced at industrial scale at Giyani’s demonstration plant in South Africa.
The company will supply additional quantities of HPMO for Phases 2 and 3 of C4V’s qualification program.
Next Phases: Cell Testing and Performance Evaluation
Phase 2 testing—expected to take about five months—will involve single-layer pouch cell testing to evaluate long cycling, stability, and rate performance.
Phase 3 will follow, focusing on multi-layer pouch cell testing over approximately six months.
“These Phase 1 results mark an important milestone for Giyani,” said interim executive chairperson Nigel Robinson on October 21.
“Our HPMO not only meets the required specifications but also performs strongly in C4V’s coin cell analysis. This is a crucial step toward validating our product through independent third-party testing and advancing offtake discussions.”
C4V Confirms Positive Performance
During Phase 1, C4V conducted coin cell analysis of Giyani’s HPMO to assess electrochemical performance, including first-cycle efficiency, capacity, charge/discharge efficiency, and density.
The results confirmed that Giyani’s material met all Phase 1 standards, qualifying it for the next stages.
“We’re encouraged by the strong performance of Giyani’s HPMO,” said C4V supply chain VP Baasit Ali.
“The product aligns with our material and electrochemical benchmarks, and we look forward to progressing through the next qualification phases and deepening our collaboration.”
