Overview of Metal Powder Material Lithium ion Battery LiFePO4 Anode Material
Metal Powder Material Lithium ion Battery LiFePO4 Anode Material comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.
Key Characteristics of Metal Powder Material Lithium ion Battery LiFePO4 Anode Material
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Metal Powder Material Lithium ion Battery LiFePO4 Anode Material
Lithium iron phosphate (LiFePO4), also known as LFP, is a popular anode material in lithium-ion batteries due to its safety, high capacity, and good thermal stability. Here are some key parameters for LiFePO4 anode material:
1. **Chemical Formula**: LiFePO4
2. **Nominal Voltage**: 3.2-3.6 V (vs. Li+/Li)
3. **Specific Capacity**: ≈170mAh/g (at higher C-rates) to ≈180mAh/g (at lower C-rates)
4. **Cycling Stability**: Excellent long-term cycle life, typically over 2,000 cycles at 80% depth of discharge (DoD)
5. **Safety**: Lower risk of thermal runaway compared to other lithium-ion anode materials like graphite
6. **Rate Capability**: Moderate rate capability, but not as fast as graphite (good for moderate to high power applications)
7. **Electrochemical Reaction**: During discharge, LiFePO4 loses Li+ ions to form Li0.9FePO4, while during charge, it takes up Li+ ions to reform LiFePO4
8. **Particle Size**: Fine particle sizes (typically submicron or nanoscale) improve the surface area for better electrochemical performance
9. **Density**: ≈7.2 g/cm³, which is relatively low compared to graphite but contributes to lightweight battery design
10. **Environmental Impact**: LFP has a lower environmental impact due to the non-toxicity of its elements
Please note that these values may vary depending on the specific synthesis method, processing conditions, and the quality control measures of the manufacturer.
