[SMM Tin Morning Briefing: The Most-Traded SHFE Tin Contract Opened Sharply Lower in the Night Session and Remained Rangebound at Low Levels, While Trading in the Spot Market Was Relatively Mediocre]

This week，the solid-state battery industry showed a dual-engine momentum driven by "intensive breakthroughs on the technology front and targeted solutions on the policy front." CATL disclosed a sulphide patent, Zhongkeyuanben's 20Ah all-solid-state battery passed third-party detection, and Dreame Technology released a 450Wh/kg product; Guangdong took the lead in incorporating diversified solid-state battery technology routes and eVTOL scenarios into provincial-level action plans.

This week, prices for some Grade-B battery cells in the second-life battery market rose. Cost side, lithium carbonate prices fluctuated more sharply this week and showed an overall upward trend, directly pushing up battery cell production costs; nickel sulphate prices edged up, while cobalt sulphate prices remained stable, providing mild support on the cost side and lifting overall cost pressure somewhat. Supply side, the market was clearly boosted by energy storage demand, enterprises showed relatively strong willingness to sell, and circulating supply was steadily released; coupled with rising lithium carbonate prices, enterprises' expectations for higher costs strengthened, and overall pricing sentiment remained firm to slightly stronger. Demand side, demand for second-life Grade-B battery cells recovered significantly, mainly driven by the energy storage market, as downstream energy storage projects commenced and supporting demand continued to be released, noticeably boosting procurement enthusiasm.

As of this Thursday, the average SMM battery-grade nickel sulphate price rose WoW. Demand side, some producers recently began making inquiries, and procurement sentiment improved somewhat, but as downstream orders remained unclear, they still took a wait-and-see attitude toward high-priced nickel salt. Supply side, due to uncertainty in Indonesian MHP supply recently, some producers expected raw material costs to rise and raised their offers accordingly. Looking ahead, Q2 is about to begin. Attention should be paid to support from the raw material side for nickel sulphate prices. Inventory side, this week the inventory index at upstream nickel salt smelters remained at 4.7 days, the inventory index at downstream precursor plants fell from 7.4 days to 7.1 days, and the inventory index at integrated enterprises declined from 7 days to 6.8 days. In terms of buyer-seller balance, this week the Willingness to Sell Sentiment Factor at upstream nickel salt smelters remained at 1.8, the procurement sentiment factor at downstream precursor plants remained at 2.7, transaction sentiment recovered slightly, and the sentiment factor at integrated enterprises remained at 2.4. (Historical data is available in the database.)

[SMM Daily Brief Review of Coking Coal and Coke] In terms of supply, coke producers' profits were weak, coupled with the relatively small room for coal mines to offer concessions, which did not fully restore coke producers' profits. As a result, their willingness to increase output was low, and they maintained normal production. On the demand side, the Two Sessions are about to conclude, and steel mills that had previously imposed voluntary production restrictions are expected to resume production, which may increase demand for coke. However, due to the slow destocking speed of finished steel products, steel mills remained cautious toward coke and adopted a purchase-as-needed strategy. In summary, with steel mills purchasing cautiously and coke producers' cost downside room limited, the coke market may remain temporarily stable in the short term.

On the demand side, the EV battery market has seen order contractions compared to earlier expectations, impacted by lackluster new energy vehicle sales both domestically and internationally.

[SMM Weekly Survey of the Aluminum Downstream Sector: Downstream Aluminum Operating Rate Continued to Rebound to 61.9%, with High Prices Suppressing the Peak "Golden March" Season] This week, the weekly operating rate of leading downstream aluminum processing enterprises in China rose 2.4 percentage points MoM to 61.9%, overall extending the post-holiday recovery trend, with all segments rebounding MoM, and the industry as a whole entering a normal production pace.

Refined Cobalt: This week, spot refined cobalt fluctuated rangebound around 430,000 yuan/mt. On the supply side, mainstream smelters slightly lowered ex-factory prices, while traders' spot-futures price spread remained stable: regular brands were at discounts of 2,000 yuan/mt to parity, and high-end brands at premiums of 5,000–8,000 yuan/mt. On the demand side, cost pass-through downstream remained sluggish, with market participants mainly staying on the sidelines. Only sporadic rigid-demand restocking emerged, and transactions had yet to gain volume. Fundamentally, the arrival period for cobalt intermediate products remained unclear, and the structural tightness in raw materials was unchanged, leaving support at the bottom still in place. Looking ahead, as restocking demand is gradually released, refined cobalt prices are still expected to have upside room. Cobalt Intermediate Products: This week, cobalt intermediate product prices continued to hold steady. On the supply side, miners' export progress was slow, holders temporarily held back offers, and spot cargo available for circulation was scarce. On the demand side, raw material shortages at smelters worsened. Although purchase willingness remained, both buyers and sellers stayed cautious due to unstable supply and unclear downstream orders, and the market continued to see "offers but no trades." Overall, export delays cast doubt on the timing of bulk arrivals, and the structural tightness in raw materials in China may worsen further; once downstream orders are finalized and procurement restarts, intermediate product prices are still expected to have upward momentum. Going forward, attention should be paid to export progress in the DRC and the pace of demand recovery. Cobalt Sulphate: This week, spot cobalt sulphate prices held steady. On the supply side, supported by tight raw materials, most smelters kept offers firm in the 95,000–98,000 yuan/mt range; small smelters and traders under capital pressure had already completed cashing out from last week to early this week, and low-price offers in the market narrowed. On the demand side, uncertainty over downstream orders persisted, with most enterprises remaining on the sidelines. Post-holiday stockpiling willingness had yet to start, with only sporadic rigid-demand restocking and priority given to lower-priced cargoes. In the short term, the market remained in a period of social inventory digestion, with rangebound adjustments dominating; however, the raw material supply bottleneck in the DRC remained unresolved, domestic supply tightened periodically, and cost support still existed. After low-priced inventory is depleted, prices are expected to resume their rise.

[SMM Lithium Battery Electrolyte Market Weekly Review: Electrolyte Prices Remained Temporarily Stable This Week (2026.3.9-3.12)] From March 9 to March 12, 2026, electrolyte prices remained temporarily stable. Considering the overall trend in cost-side changes and the supply-demand pattern, electrolyte prices were expected to remain temporarily stable in the short term.

This week, ternary cathode precursor prices were broadly stable. Raw materials, nickel sulphate prices edged up today, while cobalt sulphate prices and manganese sulphate prices held steady. Discounts, for March orders, as raw material prices were expected to rise to some extent, some producers recently showed willingness to raise nickel discounts. Long-term contracts, as downstream orders remained unclear, acceptance of higher discounts did not improve significantly and was basically flat from February. Spot orders, discounts for some earlier orders had already been finalised before the Chinese New Year, while discounts for the remaining March orders rose slightly from February; production, precursor production schedules in March recovered overall from February, with some leading producers in China and producers with relatively large export orders maintaining high operating rates. Looking ahead, sulphate prices have recently remained generally firm and may provide further support for precursor prices from the cost side.
