MSE PRO™ Sodium Manganese Phosphate (NaMnPO4) Powder for Sodium Ion Battery Cathode

Sodium-ion batteries (SIBs) have been recognized as one of the most potential technologies for low-cost rechargeable batteries due to the abundant resource of sodium from ocean or iron sand. SIBs possess a similar cell configuration and working mechanism for energy storage with lithium-ion batteries (LIBs). However, Sodium ion (Na+) intercalation and storage, owing to larger ionic radius of 1.02 Å and heavier weight of 22.99 g.mol−1 compared with Li+ (0.76 Å & 6.94 g.mol−1), are more challenging than Li-ion batteries. 

High-performance phosphate-based electrodes including transition metals such as
manganese and iron have been proven as potential SIB cathode materials due to their solely inexpensive fabrication. Sodium manganese phosphate (MaMnPO4) goes through reversible redox Mn3+/Mn2+ pair with a Na+ diffusion process.

The NaMnPO4 particle powders are covered with 3 wt% carbon to improve the electrical conductivity and electrolyte wetting.

More SIB cathode materials such as Sodium Iron Phosphate (NaFePO4) and Sodium manganese Oxide (Na0.44MnO2) are also available from MSE Supplies LLC, please contact us.
