Lithium Carbonate Market Weekly Review: 8.31-9.3 spot lithium carbonate prices rose first then fell, overall downward trend [SMM Weekly Review]

Today, SMM battery-grade lithium carbonate spot prices edged down from the previous working day. The lithium carbonate 2701 contract opened higher at 156,000 yuan/mt today, then moved sideways above the average price line in early trading, reaching an intraday high of 158,000 yuan/mt. Around midday, bears stepped up selling pressure, sending prices off a cliff and below the average price line. In the afternoon, prices consolidated on a weak note at lows; despite a brief rebound, they failed to break above the average price line, hitting a low of 149,500 yuan/mt. Near the close, prices consolidated at lows in the 149,800–150,000 yuan range, ultimately closing down 3.71% at 149,900 yuan/mt, with open interest down 1,517 lots.

This week, China's lithium carbonate supply continued to recover, mainly driven by the completion of maintenance and gradual production resumptions at some lithium chemical plants using spodumene, lepidolite, and salt lake sources, while the recycling segment maintained normal production. In terms of market transactions and inventory changes, with the start of the month, upstream lithium chemical plants successively shipped long-term contract volumes. A small number of lithium chemical plants showed increased willingness to sell spot orders as prices rose above 160,000 yuan/mt this week, leading to a reduction in inventory. Downstream material plants, despite a continued increase in consumption, saw basically stable inventory as long-term contracts and customer-supplied materials were successively delivered, and their willingness to purchase spot orders gradually strengthened as prices fell below 155,000 yuan/mt. Traders saw a slight inventory drawdown as upstream spot shipments edged up and downstream spot purchases remained normal.

SMM Daily Review: Lithium Carbonate Spot Prices Edge Down on September 3

A leading petrochemical plant halted one production resumption line yesterday, and today another line started producing LDPE. In the short term, the enterprise's production schedule will maintain parallel production of one high-pressure material line and one PV material line. After this line adjustment, the plant's PV material output scale has contracted somewhat.

On August 31, 2026, the Huaneng Shaanxi Shenmu 100,000 kW PV power generation project achieved full-capacity grid connection, marking that the installed capacity of Huaneng Shaanxi New Energy Branch exceeded 3 million kW.

Since the commencement of the Shenmu project, in the face of multiple challenges such as frequent windy and sandy weather in northern Shaanxi, complex terrain and landforms, constrained construction conditions, and tight schedule periods, all builders have united their efforts, overcome difficulties, and pursued excellence. They strictly implemented safety production and quality control requirements, scientifically coordinated construction plans, optimized construction process flows, and orderly advanced key tasks including booster station construction, solar panel mounting bracket installation, module laying, collector line installation, and equipment debugging and calibration. Through refined management, standardized construction, and regularized problem-solving, they efficiently resolved various difficulties and bottlenecks during the construction process, steadily advanced the project construction progress, and successfully completed the perfect conclusion from first grid connection to full-capacity grid connection, fully demonstrating Huaneng's speed, Huaneng's responsibility, and Huaneng's quality.

[Solid-state battery: Tianneng Battery achieves large-scale delivery of semi-solid-state 314Ah battery cells, with multi-technology systems making breakthroughs in stages] On 28 August 2026, Tianneng Battery disclosed in its H1 2026 semi-annual report that the semi-solid-state 314Ah battery cells produced in cooperation with WELION New Energy have achieved large-scale batch delivery and have been successfully applied first to grid-side ESS equipment. The company has laid out multiple new-type battery technology routes, including solid-state batteries, sodium-ion batteries and hydrogen fuel cells, and its "lithium-lithium-hydrogen-sodium + solid-state" multi-technology system is accelerating its formation, with the industrialisation process showing a staged progression of "sodium-ion battery demonstration and verification, solid-state battery deployment in multiple scenarios, and accelerated commercialisation of hydrogen fuel". The company's lithium battery business has significantly accelerated its push to go global, with residential ESS outside China as a key breakthrough direction. For specific H1 financial data, please refer to the full report. Semi-solid-state battery: solid-liquid battery.

[Solid-State Battery: EcoPro BM Forms All-Solid-State Battery Team Covering the Full "Raw Material-Material-Battery Cell" Chain, Targeting Commercialization by 2027] On August 26, 2026, EcoPro BM held a kick-off meeting in Gyeonggi Province, officially forming an "all-solid-state battery team" covering the full "raw material-material-battery cell" chain. The project is led by South Korea's Ministry of Trade, Industry and Energy, and EcoPro BM was selected in early August, along with four other enterprises, as a third-phase "super subcontractor" company. Team participants include the Korea Electronics Technology Institute (KETI), the Korea Institute of Science and Technology (KIST), Pohang University of Science and Technology (POSTECH), Hanyang University, and others. EcoPro BM plans to develop sulphide-based solid electrolytes based on high-purity lithium sulphide, with the goal of commercializing sulphide-based all-solid-state batteries by 2027. Reported by Yonhap News Agency and other South Korean media on August 31.

At Intersolar South America in Brazil (Aug 25-27), around 20 Chinese energy storage companies exhibited. Chuneng New Energy signed agreements with four partners, including MOUs with Argentina's Intermepro and Brazil's ION Energy and JSN Energia, plus a 1.5GWh cell framework deal with Windey Energy to supply cells for its first overseas storage plant in Bahia, Brazil. With a fragile grid, a 20.6% curtailment rate and the world's second-highest residential power prices, Brazil will launch Latin America's largest national storage tender (about 18GW in round one) in December 2026, drawing CATL, Trina, Hithium, CLOU, Gotion and Great Power to expand locally.

On Aug 30, Xibei Power signed a high-performance sodium-ion battery production base project in Zigong High-tech Zone, Sichuan, with a total investment of 250 million yuan. Upon completion, it will have an annual capacity of 0.5GWh and is expected to generate 500 million yuan in annual sales, with phased expansion planned toward a long-term capacity of 10GWh.

According to Ecora Royalties’ 2026 interim results released on September 2, the company received 266 tonnes of cobalt through its Voisey’s Bay cobalt stream in the first half of the year, up about 90% from 140 tonnes in the same period of 2025. Ecora said the ramp-up of underground mining operations at Voisey’s Bay is now substantially complete.
Driven by higher cobalt volumes and stronger prices, the project’s portfolio contribution after stream costs rose to US$13.5 million in the first half, up 230% year on year, while the average realized cobalt price increased to US$28.4/lb from US$16.5/lb a year earlier.
Meanwhile, Vale Base Metals is studying an expansion of the Voisey’s Bay concentrator’s processing capacity from around 2.8 million tonnes per year to 3.8 million tonnes per year. The related pre-feasibility study remains underway, with a final investment decision targeted around 2028. The project also plans both underground and surface drilling in 2026 to optimize the mine plan, support resource expansion and potentially extend mine life.
Ecora also said planned maintenance is scheduled at the Voisey’s Bay concentrator in the third quarter and at the Long Harbour refinery in the fourth quarter.
