[SMM Weekly Review] Battery Cells for Energy Storage in the Second-Life Application Market Remained in Undersupply, with Structural Price Increases, 2026.03.16-2026.03.19
This week, the second-life battery market showed clear structural divergence. On the cost side, although lithium carbonate prices saw a temporary uptick this week, they trended downward overall; nickel sulphate prices edged down slightly, while cobalt sulphate prices remained stable. The cost side was mainly affected by fluctuations in lithium carbonate prices. On the supply side, driven by terminal energy storage demand, inventories of new battery cells at battery cell manufacturers were critically low, and the supply of Grade A battery cells was heavily diverted, causing supply in the second-life battery market to remain tight. On the demand side, 280Ah and 314Ah energy storage battery cells were subject to concentrated procurement in the market, resulting in severe shortages and noticeably rising prices. Meanwhile, demand in the EV sector remained weak, inventory was relatively sufficient, and second-life power battery cell prices stayed stable.
