Manganese X Energy Announces Breakthrough Phase 2 Battery Test Results with 70% Capacity Retention After 4,600 Cycles and Advances to Phase 3 Testing with U.S. Battery Innovator C4V

Executive Summary

• Manganese X Energy Corp. announced successful completion of Phase 2 battery testing with Charge CCCV, achieving 70% capacity retention after 4,600 cycles – more than double the life of conventional NMC batteries.
• The results support advancement to Phase 3, which will evaluate the material in multilayer (3 Ah) pouch cells and move the company closer to a strategic partnership and potential binding offtake agreement with C4V.
• The high‑purity manganese used is sourced from the Battery Hill project, positioning Manganese X as a prospective domestic supplier for EV and BESS markets.

Key Details

• Phase 2 Outcome: 70% capacity retention after 4,600 full charge‑discharge cycles (60 min charge / 60 min discharge / 5 min rest).
• Performance Comparison: Cycle life >2× that of conventional NMC chemistries and superior to LFP and LMFP benchmarks.
• Testing Partner: U.S. battery innovator Charge CCCV (C4V) under its Digital DNA Supply Chain Qualification Program.
• Next Milestone – Phase 3: Evaluation in multilayer pouch cells (3 Ah design) to meet end‑user product requirements; successful results will further validate commercial adoption potential.
• Strategic Implication: Positive test data strengthens Manganese X’s case for a strategic partnership and possible binding offtake deal with C4V.
• Resource Basis: High‑purity manganese derived from the Battery Hill project in Woodstock, NB – one of the largest MnCO₃ deposits in Canada/US.
• CEO Comment (Martin Kepman): “These exceptional test results validate the superior quality of our Battery Hill manganese… could lead to securing a potential binding offtake deal.”
