Physical Properties

ParameterValueDescription
Average Particle Size (D₅₀)5μm / 9μmTwo specifications are available. The 5μm and 9μm grades meet different processing and battery performance requirements.
Specific Surface Area (SSA)4m²/g (for 9μm grade); 6.0m²/g (for 5μm grade)The moderate specific surface area helps balance the formation of the solid electrolyte interphase (SEI) film and the rate of sodium - ion adsorption.
True Density1.48g/cm³Ensures good compactibility when preparing anode electrodes, which is conducive to improving the energy density of batteries.
Average Interlayer Spacing (d₀₀₂)0.38nmWider than that of graphite, this spacing significantly enhances the diffusibility of sodium ions and optimizes the charge - discharge response speed of the battery.
Moisture ResistanceLowIt can be compatible with water - based binders such as SBR/CMC, reducing the environmental impact and cost of electrode preparation processes
