Ronbay Secures Major Sodium-Ion Battery Cathode Order, Strengthening Market Presence

Ningbo Ronbay

Expanding Sodium-Ion Battery Cathode Production

Ningbo Ronbay, a leading Chinese battery cathode active material (CAM) manufacturer, has secured a 3,000-tonne order for sodium-ion battery cathode material from an undisclosed client. The company announced the deal on January 20, reinforcing its position as a key player in China’s sodium-ion battery market.

Ronbay has been heavily investing in sodium-ion cathode materials, committing 3 billion yuan ($413 million) in September 2023 to construct a 50,000-tonne-per-year production complex, which is set to launch by 2026. This investment aligns with the growing global demand for sodium-ion batteries, expected to reach 23GWh in 2025.

China’s Sodium-Ion Battery Industry Gains Momentum

China’s leading battery manufacturers, including CATL, BYD, and Hithium, have accelerated their sodium-ion battery production. BYD, for example, started construction on a 30 GWh per year sodium-ion battery plant in Xuzhou, Jiangsu province, in early 2024. These expansions indicate increasing market confidence in sodium-ion battery technology, particularly for two-wheeled and three-wheeled vehicles, energy storage, and power applications.

The Chinese government has also actively promoted sodium-ion battery development as part of its 2021-2025 energy strategy, emphasizing the battery’s cost advantages, resource abundance, and environmental benefits compared to lithium-ion batteries. However, despite strong governmental backing, sodium-ion battery shipments in 2024 fell short of earlier expectations due to higher manufacturing costs compared to lithium-ion and lead-acid batteries, according to Chinese research institution EV Tank.

Ronbay’s Role in the Growing Sodium-Ion Market

With this latest order, Ronbay strengthens its leadership in sodium-ion cathode production, ensuring steady market growth despite industry challenges. The company’s large-scale investment and expanding production capacity position it to capitalize on rising sodium-ion battery adoption while supporting China's push for alternative battery technologies.

As demand for low-cost and sustainable energy storage solutions rises, sodium-ion batteries could play a crucial role in diversifying the global battery supply chain, particularly as a viable alternative to lithium-ion technology.
