Sodium Manganese Iron Phosphate (NaMnxFe1-xPO4), often abbreviated as NMFP, is an advanced polyanionic cathode material developed for sodium-ion batteries (SIBs). By combining iron and manganese within the olivine phosphate framework, NMFP offers an excellent balance of high operating voltage, good cycling stability, enhanced safety, and cost-effectiveness.
As a cobalt- and nickel-free cathode material, NMFP is considered an ideal candidate for next-generation energy storage systems. VIMATERIAL offers NMFP powders in various proportions. Contact us for more information.
Formula: NaMnxFe₁₋xPO₄ (the Mn/Fe ratio can be adjusted depending on performance requirements).
Appearance: Typically black powder
Density: ≥ 3.3 g/cm³ .
Specific Capacity: > 100 mAh/g.
Structure: Crystallizes in an olivine-type crystal structure, providing stable sodium-ion insertion and extraction pathways while maintaining excellent structural integrity during charge and discharge.
Cathode Material for Sodium-Ion Batteries: It is primarily used as a cathode material in sodium-ion batteries, offering high energy density, long cycle life, and enhanced operational safety. It serves as an attractive alternative to lithium-based cathode materials, particularly in applications where raw material cost and resource availability are important considerations.
Grid Energy Storage Systems: Due to its excellent cycle stability, thermal safety, and low material cost, NMFP is well suited for stationary energy storage systems, including renewable energy integration, smart grids, and backup power applications.
Electric Mobility: It is increasingly being explored for electric vehicles, electric two-wheelers, low-speed electric vehicles, and commercial transportation, where safe operation, long service life, and cost efficiency are essential.
Industrial and Portable Energy Storage: The material is also suitable for industrial power systems, portable energy storage devices, telecommunications backup power, and other applications requiring reliable and durable battery performance.
Handling: Handle under normal laboratory and industrial conditions. As a fine powder, appropriate protective equipment should be used to minimize dust inhalation.
Storage: Store in a cool, dry environment away from excessive moisture and contaminants. Proper sealing is recommended to preserve material quality and ensure consistent electrochemical performance during long-term storage.
Q1: What is the difference between NMFP and NFP?
A: NMFP contains both manganese and iron, while NFP (Sodium Iron Phosphate) contains only iron. The addition of manganese increases the operating voltage and improves the energy density of the battery.
Q2: What applications is NMFP powder suitable for?
A: It is widely used in:
Q3: Is carbon coating available?
A: Yes. Carbon-coated NMFP powders are available to improve electronic conductivity and enhance battery performance. Different carbon coating contents can be customized based on customer specifications.
Q4: Do you provide customized specifications?
A: Yes. Customized specifications are available, including:
