Manganese X Energy Corp. (TSX-V: MN) (FSE: 9SC) (TRADEGATE: 9SC) (OTCQB: MNXXF)  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.”

Phase 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 EV and BESS market segments. The results were outstanding, with the material achieving 70% capacity retention after 4,600 full charge-discharge cycles. Each cycle consisted of a 60-minute charge, a 60-minute discharge, and a 5-minute rest period, between charge and discharge, demonstrating remarkable stability and resistance to capacity fade.

Battery Hill: A Premier Manganese Resource

The High Purity manganese tested was produced from the Company’s Battery Hill project, recognized as one of the largest manganese carbonate deposits in Canada and the United States. This resource underpins Manganese X’s mission to supply sustainable, high-quality materials for the growing EV markets.

Next Step: Phase 3 Testing
Manganese X is now proceeding to Phase 3 of C4V’s qualification program, which will evaluate the material in multilayer pouch cells (3Ah design) to meet end-user product requirements. Successful results from the final phase will further validate the material’s performance in advanced battery designs, paving the way for commercial adoption.

About Manganese X Energy Corp.
Manganese X’s mission is to advance its Battery Hill project into production, thereby becoming the first public actively traded manganese mining company in Canada and US to commercialize EV compliant high purity manganese, potentially supplying the North American supply chain. The Company intends on supplying value-added materials to the lithium-ion battery and other alternative energy industries, as well as striving to achieve new carbon-friendly more efficient methodologies, while processing manganese at a lower competitive cost.
