Ronbay Expands Global Cathode Material Output in 2024

Chinese battery materials manufacturer Ronbay significantly boosted battery cathode active material (CAM) output and sales in 2024. The company produced 137,351 tonnes of CAM, a 34% increase year-on-year, driven by strong electric vehicle (EV) sector demand.

CAM sales reached 121,688 tonnes, up 16%, including 120,000 tonnes of NCM (nickel-cobalt-manganese oxide). Ronbay is the world’s largest NCM producer, holding 12% of global market share, according to industry data.

Diversification and Global Expansion Underway

Ronbay also produces LMFP and sodium-ion CAM, expanding its portfolio after acquiring Tianjin Skylandone in 2022. The firm’s total CAM capacity reached 200,000 t/yr by the end of 2023, with facilities across China and South Korea.

The company is constructing a 40,000 t/yr NCM plant in South Korea, set to begin trial production in the first half of 2025. It is also building a 20,000 t/yr NCM facility in Poland and establishing operations in the US to serve growing Western battery markets.

EV Sector Growth Fuels CAM Demand

China’s new energy vehicle (NEV) production and sales both grew by over 34% in 2024, CAAM reported. This growth reinforced Ronbay’s strong CAM performance and supported its aggressive expansion strategy.

Ronbay aims to produce 130,000–150,000 tonnes of CAM in 2025, targeting both domestic and global battery manufacturers.

The Metalnomist Commentary

Ronbay’s expansion reflects a clear upstream strategy to meet diversified battery chemistries and regionalized supply needs. As NEV markets boom, the globalization of CAM production will be a defining trend in battery materials over the next decade.
