MSE PRO Sodium Manganese Phosphate (NaMnPO₄) Powder for Sodium Ion Battery Cathode, 50g

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 (Na_0.44MnO₂) are also available from MSE Supplies LLC, please contact us.
