(TSXV: MN) (FSE: 9SC) (TRADEGATE: 9SC) (OTCQB: MNXXF) (\"Manganese X\" or the \"Company\") is pleased to announce it is advancing to the final Phase 3 of Battery Testing following the successful completion of Phase 2 testing with U.S. battery innovator company Charge CCCV (C4V), which resulted in an exceptional outcome of 70% capacity retention after 4,600 cycles. This performance represents more than double the cycle life of conventional NMC-based EV batteries and significantly outperforms even robust Lithium Iron Phosphate (LFP) and Lithium Manganese Iron Phosphate (LMFP) chemistries. These breakthrough results underscore the potential of Manganese X's High-Purity Battery Grade Manganese, serving as a game-changing material in the global EV and Battery Energy Storage System (BESS) market segments.Manganese X's battery-grade manganese material is sourced from its Battery Hill project in Woodstock, New Brunswick, Canada. The rigorous commercial-level qualification standards were set and tested by US battery innovators in C4V as part of its Digital DNA Supply Chain Qualification Program. Manganese X CEO Martin Kepman stated, \"These exceptional test results validate the superior quality of our Battery Hill manganese and not only brings us closer to establishing a strategic partnership with C4V but could lead to us to securing a potential binding offtake deal. Our material's durability and stability could potentially set a new benchmark for battery performance, and we are excited to advance to Phase 3 to further demonstrate its potential in multilayer pouch cell designs.\"Exceptional Phase 2 ResultsFigure 1: Phosphate family cycle life comparison and relative performance vs. BMLMP (C4V test result).To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/2487/265412_12a8cada8465fa62_002full.jpgPhase 2 testing focused on evaluating the long-term performance and durability of Manganese X's high-purity manganese in C4Vs single-layer pouch cells, representative of commercial battery designs for various end applications in ...
