Manganese X Energy Joins POSCO and NRC in Advanced Battery Cathode Research

Manganese X Energy (TSXV: MN | OTCQB: MNXXF) has entered into a research collaboration with the National Research Council of Canada, POSCO, E3 Lithium and NiVolt Technologies.

10 kg of high-purity manganese sulfate (HPMSM) have already been successfully produced from our Battery Hill ore and supplied to the research project for the development of next-generation lithium-manganese-rich (LMR) cathode materials.

This is an important development for Manganese X and its shareholders.

POSCO, one of the world's leading battery materials companies, will conduct technical verification and performance assessments of the materials.

The collaboration provides an opportunity to demonstrate the potential of Battery Hill manganese in advanced battery applications and strengthen our position in the North American battery supply chain.

It's another meaningful step toward potential future commercial applications.
