CATL locks in massive $17.2B LFP supply deal with Ronbay to secure future battery materials
News, 15 January 2026
China’s Contemporary Amperex Technology Co. Ltd. (CATL), the world’s largest electric vehicle (EV) battery maker, has signed a landmark long-term agreement with Ningbo Ronbay New Energy Technology to secure its future supply of lithium iron phosphate (LFP) cathode materials a key component for EV batteries. Under the deal, Ronbay will deliver approximately 3.05 million tonnes of LFP materials to CATL’s operations from the first quarter of 2026 through 2031, with total contract sales expected to exceed RMB 120 billion (roughly $17.2 billion). This agreement stands out as one of the largest material supply contracts in the global battery industry, reflecting the intense competition for reliable access to essential EV raw materials.
The scale of this supply pact highlights both the growing demand for LFP batteries known for their cost advantages and safety characteristics and CATL’s strategy to lock in upstream resources as EV adoption accelerates worldwide. Industry reporting notes that Ronbay, which entered the LFP materials space in 2025, is gearing up for this substantial production volume while the Shanghai Stock Exchange has asked the company to clarify aspects of its production capacity and risk factors related to raw material price volatility and fulfillment capabilities.
Beyond securing raw material supply, CATL is also deepening its involvement in the battery materials ecosystem. The company plans investments in other LFP material suppliers, such as Fulin Precision Machining, underscoring a broader effort to strengthen its supply chain foothold and mitigate potential bottlenecks. This aggressive procurement and investment strategy comes against a backdrop of rising battery costs including recent surges in battery-grade lithium prices which have put pressure on manufacturers globally to ensure steady, cost-effective access to critical inputs.
Overall, this deal not only signals CATL’s commitment to scaling EV battery production but also marks a notable shift in how major battery makers are proactively managing supply chain risks in a rapidly evolving global EV market.
