According to Yonhap Infomax, LG Chem (KRX: 051910) said during its Q2 2026 earnings call on July 31 that it is developing high-power sodium-ion battery materials with a target of mass production by the end of 2027, and plans to commercialise long-life, high-capacity materials in earnest in 2029. The report also notes that LG Chem previously signed a joint development agreement with China’s Sinopec for sodium-ion battery materials, which predates this statement. The information was provided by management on an earnings call and reflects public remarks.
This is a company target and plan (earnings-call statement), not accomplished mass production. The report discloses no capacity, customer or order details for the high-power materials, and the timeline could shift with technology validation, cost trends and customer adoption. “Targeting end-2027 mass production” should not be read as existing production or confirmed shipment arrangements.
