Montreal, Quebec–(Newsfile Corp. – June 16, 2026) – Manganese X Energy Corp. (TSXV: MN) (FSE: 9SC) (TRADEGATE: 9SC) (OTCQB: MNXXF) (“Manganese X” or the “Company“) is pleased to provide an update on its battery materials qualification program with Charge CCCV LLC (“C4V“). The Company’s high-purity manganese material has advanced to Phase 3, the final stage of C4V’s battery qualification program: Multi-Layer Full Pouch Cell Evaluation. This commercial-level testing is part of C4V’s Digital DNA Supply Chain Qualification Program.
C4V has informed the Company that its initial engineering analysis indicates Manganese X’s high-purity manganese material meets the initial rigid specifications and performance requirements for advancement to this final testing phase. The Phase 3 Multi-Layer Full Pouch Cell Evaluation is expected to take approximately six months, with interim performance updates anticipated during the program.
Manganese X’s battery-grade manganese material is sourced from its Battery Hill project, one of the largest manganese deposits in North America. The Battery Hill project is at prefeasibility stage and is located near Woodstock, New Brunswick, Canada.
CEO Martin Kepman stated, “Receiving confirmation that our high-purity manganese material has met Phase 3’s initial stringent specifications and performance requirements, reinforces our confidence in Battery Hill’s ability to supply a critical material for the North American electric vehicle battery and energy storage markets. This important advancement brings us closer to establishing a strategic partnership with C4V and may support future commercial discussions, including possible offtake agreements. Our material’s durability and stability could potentially set a new benchmark for battery performance. We are excited to advance into Phase 3 testing to further demonstrate its commercial application.”
Phase 2 testing with U.S. battery technology innovator C4V delivered strong results, with 70% capacity retention after 4,600 cycles. Based on the Company’s understanding of industry benchmarks, this indicates better cycle life than conventional NMC-based EV battery chemistries and compares favourably with Lithium Iron Phosphate (LFP) and Lithium Manganese Iron Phosphate (LMFP) chemistries. These findings highlight the potential of Manganese X’s high-purity, battery-grade manganese as a strategic material for the global Electric Vehicle and Battery Energy Storage System (BESS) markets.
Phase 3 Testing:
Phase 3 of C4V’s qualification program, is evaluating the Battery Hill material in multilayer pouch cells (3Ah design) to meet end-user product requirements. Successful results from this final phase will further validate the material’s performance in advanced battery designs, paving the way for commercial adoption.
