Packaging, Storage and Global Logistics Compliance

Sodium-ion hard carbon materials demand rigorous moisture protection and safe handling during international transit. We ensure your materials arrive in pristine condition:

Moisture-Barrier Packaging: Multi-layer moisture-proof vacuum aluminum foil packaging combined with inner polyethylene (PE) bags to prevent ambient moisture adsorption.

Flexible Quantities: Available in standard laboratory sample sizes up to industrial bulk drums or custom super-sacks.

Global Shipping and Regulatory Support: Provided with complete Non-Dangerous Goods declarations (or compliant hazardous materials documentation where applicable), Material Safety Data Sheets (MSDS/SDS), and full export customs clearance documentation.

Recommended Storage Guidelines: Store in a cool, dry, well-ventilated environment away from direct moisture and humidity sources. Keep containers hermetically sealed when not in use.

FAQ

Q: What makes hard carbon superior to conventional graphite in sodium-ion cells?

A: Conventional graphite struggles with thermodynamic sodium intercalation due to larger sodium ion radii. Hard carbon features an expanded, disordered turbostratic carbon structure and a developed nanopore network that facilitate favorable insertion and adsorption mechanisms for sodium storage.

Q: Can I request customized hard carbon particle size distributions?

A: Yes. We offer customization options for specific particle size cuts (e.g., tailored D50 or narrow span) and surface treatments. Contact our engineering team with your specific requirements.

Q: What is the standard lead time for sample and bulk orders?

A: Standard laboratory sample quantities are typically available from stock or within a short lead time. Bulk production lead times depend on volume and custom specifications; our team will provide a clear schedule upon inquiry.

Q: How should hard carbon anode powders be stored?

A: To maintain electrochemical integrity and prevent moisture absorption, store materials in their original sealed packaging within a dry, climate-controlled environment. Refer to the specific product TDS for detailed guidelines.
