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
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
Montreal, Quebec – September 09, 2025 – Manganese X Energy Corp. (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 Results

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.
