Manganese X Energy (TSX-V:MN) has secured approval from the US Patent Office for its proprietary purification process of manganese sulphate — a critical material used in the production of lithium-ion batteries for electric vehicles and stationary energy storage systems.
The patent complements the company’s continuing development of the Battery Hill Project in New Brunswick, Canada, and its downstream high-purity manganese processing and commercialisation strategy.
CEO Martin Kepman says the granting marks a milestone, following the recent patent acceptance in South Africa.
“We continue to position Manganese X as a vertically integrated North American supplier of battery-grade manganese,” Kepman says.
“This achievement reinforces the strength of our technology and our commitment to building a secure and scalable domestic supply chain.”
Manganese X has also applied for patent protection in Canada, Mexico, and Australia.
High-purity manganese sulphate is a critical cathode precursor material used in lithium-ion battery chemistries, as well as emerging high-manganese formulations designed to improve performance and reduce reliance on costly or supply-constrained metals.
These advanced battery technologies play a key role in powering electric vehicles and are increasingly deployed in grid-scale energy storage, renewable energy integration, backup power systems, and a broad range of industrial and commercial applications.
