Na-HC01 Irregular Hard Carbon

Overview

HC Anode Active Material (C) Powder is an irregular hard carbon material specifically developed for sodium-ion battery (SIB) anodes. This material exhibits a disordered carbon microstructure with low graphitisation, enabling efficient sodium storage through pore filling and adsorption mechanisms rather than classical intercalation.

Hard carbon is widely regarded as the benchmark anode material for sodium-ion batteries, owing to its high reversible capacity, stable cycling behaviour, and compatibility with conventional carbonate-based electrolytes.

Working Principle

Unlike graphite, hard carbon accommodates sodium ions through a combination of:

• Adsorption on defect sites and surface functional groups, and
• Filling of nano-pores within the amorphous carbon matrix

This dual storage mechanism enables stable sodium insertion/extraction without significant structural degradation.

Key Features and Specifications

• Chemical composition: Carbon (C)
• Structure: Irregular, non-graphitised hard carbon
• Reversible capacity: ~250 mAh/g
• Physical form: Black powder
• Particle morphology: Irregular flakes (SEM-verified)
  
  

Compatibility and Integration

This hard carbon anode material is compatible with:

• Coin cells, pouch cells, and laboratory-scale SIB assemblies
• Standard sodium salts (NaPF₆, NaClO₄) in organic electrolytes
• Slurry-based electrode fabrication using PVDF or water-based binders

It is routinely evaluated using potentiostats, battery cyclers, and electrochemical test cells available through ScienceGears.

Typical Applications

• Sodium-ion battery research and development
• Academic and industrial electrode optimisation studies
• Half-cell and full-cell electrochemical evaluation
• Next-generation grid-scale energy storage research
