[Sodium Battery: Prussian Blue Sodium Battery Completes Thousand-Ton Capacity Construction]

Wu Kai, an academician of the Chinese Academy of Engineering and chief scientist of CATL, said at the 2026 Equipment Power Forum that the company will achieve mass production of a series of sodium-ion battery products this year. Compared with lithium-ion batteries, sodium-ion batteries have abundant raw material resources and lower costs. Looking ahead, lithium-air batteries will be CATL's future direction. Wu Kai explained that lithium-air batteries use lithium as the negative electrode and oxygen from the air as the positive electrode reactant, offering ultra-high theoretical energy density and representing the next global battleground for next-generation batteries.

On May 21, the Nanping Municipal Bureau of Ecology and Environment issued a notice accepting the application for the environmental impact report assessment of the high-performance sodium-ion battery cathode material and new battery system integration project by Fujian Nate Energy Technology Co., Ltd. The total investment for this project is 150 million yuan, with a construction period of 24 months, scheduled from April 2025 to March 2027. The project plans to build a production line with an annual capacity of 10,000 tons of high-performance sodium-ion battery cathode materials, as well as a production line with an annual capacity of 1GWh for new battery system integration manufacturing, along with supporting battery PACK assembly operations.

According to customs data released on May 20, 2026, China’s phosphate ore imports stood at 207,000 mt in April 2026, rising 13.5% month-on-month from 182,000 mt in March. April total import value hit US$19.741 million, a MoM increase of 35.7% versus US$14.552 million in March. The average import unit price was US$95.5 per mt, up 19.6% from US$79.9 per mt in March.
