Brunp Battery Materials Project Expands CATL’s Recycling and LFP Supply Chain

Brunp Battery Materials

Brunp battery materials project development has advanced in Yichang, Hubei province, as Guangdong Brunp Recycling Technology broke ground on a 500,000 t/yr production complex. The project carries total investment of 6.1bn yuan, or about $840 million.

The new plant is designed to produce 300,000 t/yr of iron phosphate, 180,000 t/yr of nickel sulphate and 12,000 t/yr of cobalt sulphate. Construction is scheduled for completion in the second half of 2027.

Brunp battery materials project investment strengthens the upstream materials platform behind China’s battery industry. Brunp is a controlling subsidiary of CATL, the country’s largest battery producer, and focuses on recycling, resources and battery materials.

Yichang Base Builds Scale Across LFP and Recycling

The Yichang base will become a major integrated battery materials hub once the new project is operational. It will have 750,000 t/yr of iron phosphate capacity, 450,000 t/yr of lithium iron phosphate capacity and 500,000 t/yr of battery recycling capacity.

Brunp has already made several investments in Yichang since entering the city in 2021. The company launched a 450,000 t/yr LFP factory in December, reinforcing the site’s role in China’s expanding phosphate-based battery supply chain.

This matters because LFP batteries continue to gain share in electric vehicles and energy storage systems. Large-scale iron phosphate and LFP capacity gives CATL-linked supply chains stronger control over cost, material availability and recycling integration.

Recycling Capacity Deepens China’s Battery Materials Control

Brunp Recycling processed more than 200,000t of power batteries in 2025. The company now plans to raise total recycling and processing capacity to more than 1mn t/yr by 2030.

The strategy reflects a wider shift in battery materials sourcing. Recycling is becoming a strategic source of nickel, cobalt, lithium and other battery inputs, especially as governments and manufacturers seek lower-carbon and more secure supply chains.

The Yichang project also adds nickel sulphate and cobalt sulphate capacity, linking recycling with precursor material production. However, weaker upside in metals prices has limited buyer appetite in China’s black mass market, even as NCM payables edged higher in early March.

The Metalnomist Commentary

Brunp’s Yichang expansion shows how CATL is tightening control over the full battery materials loop, from recycling to LFP and sulphate production. The project also underlines China’s advantage in building scale across both primary materials processing and circular battery supply chains.
