On June 1, CATL (03750.HK) rose 3.22% in regular trading, trading at HKD 761.5 per share, with trading volume reaching HKD 718 million. The gain was driven by a major announcement from the company's chief scientist regarding sodium-ion battery commercialization.

On the news front, Chinese Academy of Engineering academician and CATL Chief Scientist Wu Kai explicitly stated at the Equipment Power Forum that CATL will achieve mass production of a series of sodium-ion battery products this year. The company has previously announced breakthroughs in four major industry bottlenecks — extreme moisture control, hard carbon gas generation, aluminum foil adhesion, and self-generated anode mass production — with its sodium-ion battery expected to enter full-scale production supply in Q4. The company has invested nearly RMB 10 billion cumulatively in sodium battery R&D. Additionally, CATL recently secured a 3-year 60GWh sodium-ion battery strategic order with Hybridon — the world's largest sodium-ion battery order — signaling robust commercial traction for the technology.
