Na3Mn2P2C2O14

Na3Mn2P2C2O14 is a complex sodium manganese phosphate-carbonate ceramic compound that belongs to the polyanion framework family of materials. This compound is primarily of research interest as a potential cathode material for sodium-ion batteries, where its mixed-valence manganese chemistry and structural framework offer opportunities for ion transport and electrochemical cycling. While not yet established in high-volume industrial production, materials in this compositional family are being investigated as alternatives to lithium-ion systems, particularly for stationary energy storage and cost-sensitive applications where abundant sodium-based chemistries are advantageous over lithium.
