SEOUL, November 04 (AJP) - South Korea’s LG Chem said Tuesday it has formed a partnership with China’s largest energy and chemical company, Sinopec, to develop key materials for next-generation sodium-ion batteries, a technology seen as a promising alternative to lithium-based systems.
The two companies signed an agreement on Oct. 30 to jointly research and produce cathode and anode materials for sodium-ion batteries, known as SIBs. The collaboration aims to strengthen supply chain stability and improve cost competitiveness as global demand for electric vehicles and energy storage grows.
Sinopec, a state-run energy giant with operations spanning oil and gas exploration, refining, petrochemicals, and new energy, has increasingly turned its focus toward advanced materials and cleaner technologies. For LG Chem, the partnership underscores its ambition to expand its portfolio beyond lithium-ion batteries, which currently dominate the electric vehicle market.
Sodium-ion batteries offer several advantages over their lithium counterparts: the raw materials are more abundant and less expensive, performance remains stable in colder temperatures, and the technology poses lower safety risks. Analysts view them as particularly well-suited for large-scale energy storage systems and lower-cost electric vehicles.
Global sodium-ion battery capacity is expected to expand from about 10 gigawatt hours in 2025 to 292 gigawatt hours by 2034, according to industry data. China is projected to account for more than 90 percent of production by the end of the decade.
LG Chem and Sinopec plan to explore various business models in the sodium-ion sector, targeting applications in grid-scale storage and affordable electric vehicles while also expanding into eco-friendly energy and high-value chemical materials.
“As a leading global battery materials company, LG Chem has provided differentiated solutions in the global battery market,” said Shin Hak-cheol, the company’s chief executive, in a statement. “Our collaboration with Sinopec will help us develop next-generation battery materials on time and strengthen our portfolio in line with future customer strategies.”
