In 2026, the correction in lithium carbonate prices drove up lithium battery production costs. Coupled with uncertainties in lithium resources supply, cost pressure across the new energy industry became increasingly prominent. Leveraging the advantages of abundant sodium resources, balanced distribution, and controllable costs, sodium-ion batteries have leapt from being a “backup option” for lithium batteries to a key direction for industry breakthrough...

Current manufacturer expectations for this month and April remain cautious, with some companies having already lowered their April production forecasts.

Raw material side, spot lithium carbonate prices fluctuated this week, cobalt sulphate prices remained temporarily stable, and nickel sulphate prices dropped slightly.

In the spot market, during this week (March 16, 2026-March 20, 2026), downstream battery enterprises gradually resumed operations to full production, and transactions in the spot primary lead market gradually improved. This week, mainstream transaction prices for primary lead in Henan were quoted at parity or slight premiums to the SMM #1 lead average price. Supply in Hunan was relatively tight, and smelters and suppliers quoted premiums of 30-50 yuan/mt over SMM #1 lead, with transactions concluded on just-in-time demand. This week, secondary refined lead was held firm and sellers were reluctant to sell due to losses on production and other factors. After downstream operations gradually resumed, just-in-time procurement mainly focused on primary lead, and spot transactions in the primary lead market improved slightly WoW.

SMM News, March 20: This week, secondary refined lead was mostly quoted at premiums of 0-75 yuan/mt against the SMM #1 lead average price, with some cargoes available for delivered premiums of 50 yuan/mt. Affected by falling lead prices, downstream wait-and-see sentiment, and relatively cautious procurement, suppliers showed weak willingness to sell, and overall market transactions were sluggish. This week, secondary lead smelters lowered scrap battery purchase prices, easing raw material cost pressure, and losses narrowed WoW; as of March 20, 2026, the theoretical comprehensive profit/loss for large-scale enterprises stood at -337 yuan/mt, versus -541 yuan/mt for small and medium-sized enterprises (the model's by-product revenue did not include tin and antimony). As smelters that resumed production continued to release capacity, ample supply weighed on lead prices. Combined with the wide range of cargo types available to downstream enterprises, spot order premiums for secondary refined lead are expected to narrow next week, while actual prices will still depend on changes in raw material costs. > Subscribe to View Historical SMM Metal Spot Prices

On the evening of March 18, 2026, at Chery Automobile Battery Night 2026 in Wuhu, Anhui, Chery unveiled its Rhino all-solid-state battery technology. It had completed the development and pilot production of a 60Ah, 400Wh/kg all-solid-state battery cell and was advancing toward an ultra-high energy density of 600Wh/kg.

[SMM Weekly Review of the Lithium Battery Electrolyte Market: Electrolyte Prices Remained Temporarily Stable This Week (2026.3.16-3.19)] From March 16 to March 19, 2026, electrolyte prices remained temporarily stable. Considering the overall trend in cost-side changes and the supply-demand pattern, electrolyte prices are expected to remain temporarily stable in the short term.

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.

This week (March 13, 2026–March 19, 2026), multiple enterprises in the solid-state battery sector were active: Dali Times commenced construction of a 2 GWh specialized semi-solid-state battery base; EVE’s Longquan Phase III/IV all-solid-state batteries rolled off the line in Chengdu; Chery released its 600 Wh/kg Rhino all-solid-state battery technology。
