In February 2026, the solid-state battery industry accelerated its transition from pilot-scale trials to mass production, with sulphide electrolytes becoming the primary technological focus, and the national standard set to be released in July. Pilot lines such as those of Guoci Materials and Xinjie Energy were commissioned in rapid succession; 500 Wh/kg high-energy-density products were released one after another, and demand for dry-process electrode equipment surged.

[SMM Daily Review: Spot Lithium Carbonate Prices Fell Sharply on March 3] The SMM battery-grade lithium carbonate index price fell sharply from the previous working day. Futures side, after the most-traded contract opened at 170,000 yuan/mt in the morning session, it fluctuated downward throughout the session and at one point touched the limit-down price of 150,800 yuan/mt.

Overall, market inquiries were active and transaction momentum increased significantly.

According to industry sources on the 3rd, POSCO Argentina, a subsidiary of POSCO Holdings, will commence operations of the first-phase lithium brine plant by the end of this month, despite partial delays caused by supply issues involving key replacement components. Initial utilization rates are expected to start at around 60%, with full-scale operations targeted after the third quarter following equipment optimization and operational improvements. The company anticipates reaching near full capacity from July to August.
