Na-HC02 High sphericity Hard Carbon

Overview

HC Hard Carbon Anode Active Material (C) Powder is a high-sphericity hard carbon specifically engineered for sodium-ion battery (SIB) applications. Unlike graphite, hard carbon possesses a disordered, turbostratic carbon structure with enlarged interlayer spacing, enabling efficient and reversible sodium-ion storage. Sodium ions are stored through a combination of adsorption at defect sites and pore filling mechanisms, resulting in stable cycling and high reversible capacity.

Key Features and Material Specifications

• Chemical composition: Elemental carbon (C)
• Reversible capacity: 250–300 mAh g⁻¹
• Morphology: Highly spherical particles for improved packing density
• Purity: ≥99.9%
• Electrochemical behaviour: Low voltage plateau and stable solid electrolyte interphase (SEI) formation

The high sphericity enhances electrode uniformity, reduces internal resistance, and improves rate capability, making the material suitable for both laboratory-scale research and pre-commercial development.

Compatibility and Processing

This hard carbon powder is compatible with standard sodium-ion battery fabrication processes, including slurry casting with common binders and electrolytes. It integrates seamlessly with coin cells, pouch cells, and cylindrical cell formats used in electrochemical testing.

The material pairs effectively with potentiostats, battery cyclers, and electrochemical test stations supplied by ScienceGears, enabling precise characterisation of capacity, impedance, and cycling stability.

Typical Applications

• Sodium-ion battery anode research
• Next-generation grid-scale energy storage
• Low-cost and sustainable battery development
• Academic and industrial electrochemistry studies
