Hard Carbon Type-2 for Sodium-Ion Battery Anodes

1. Basic Information


Item Details
Product Name Kuraray Hard Carbon Type - 2
Application Anode material for sodium - ion batteries (SIBs)
Raw Material Eco - friendly natural plant - based precursors
Form Powder
Package Specification 200g per bottle; kilogram - scale packaging is available upon request
Storage Requirement To prevent moisture absorption, the product should be stored in a vacuum box under dry conditions


Physical Properties

Parameter Value Description
Average Particle Size (D₅₀) 5μm / 9μm Two 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 Density 1.48g/cm³ Ensures good compactibility when preparing anode electrodes, which is conducive to improving the energy density of batteries.
Average Interlayer Spacing (d₀₀₂) 0.38nm Wider than that of graphite, this spacing significantly enhances the diffusibility of sodium ions and optimizes the charge - discharge response speed of the battery.
Moisture Resistance Low It can be compatible with water - based binders such as SBR/CMC, reducing the environmental impact and cost of electrode preparation processes
