Innovation

Full-stack process innovation, from raw material to finished product

Technical Advantages

Continuous process innovation is at the heart of Tianhongji

Secondary Granulation Process

Built on our proprietary granulation platform, we precisely engineer particle size and morphology from premium coal-based needle coke. The resulting isotropic structure raises compaction density, cycle life, and rate capability — adaptable to power, ESS, and fast-charge systems.

Continuous Graphitization & Green-Power Manufacturing

Our continuous graphitization furnaces, coordinated with smart box-furnace controls, reduce per-ton energy use by over 20% versus traditional Acheson lines. Powered by Xinjiang green electricity, our products carry a lower carbon footprint to meet EU CBAM and other low-carbon procurement requirements.

Surface Coating & Modification

A multi-layer toolkit of pitch coating and CVD surface modification reshapes SEI formation, lifting first-cycle efficiency and suppressing gas evolution and Li-plating — a critical enabler for fast-charging and silicon-carbon composite anodes.
