· JVASP-55472· NaMnPO4

Sodium manganese phosphate (NaMnPO4) is an inorganic ceramic compound composed of sodium, manganese, and phosphate ions. This material is primarily investigated as a cathode material for sodium-ion batteries and energy storage systems, where its crystal structure and redox properties make it a candidate for next-generation battery chemistry that offers cost and resource advantages over lithium-based systems. While still largely in research and development phases rather than high-volume industrial production, NaMnPO4 represents the broader family of phosphate-based ceramics that are being explored to enable more sustainable and domestically sourced energy storage solutions.
