[SMM Analysis] Lithium Battery Copper Foil: No Near-Term Supply Constraint, Structural Shortage Risks to Surface in 2027
[SMM Analysis] Lithium Battery Copper Foil: No Near-Term Supply Constraint, Structural Shortage Risks to Surface in 2027
Recently, news of tightening lithium battery copper foil supply has drawn attention from the industry and capital markets. Some worry that tight copper foil supply will immediately drag down battery capacity expansion and even affect end-user deliveries. In reality, however, the copper foil constraint will not materialize right away, and the real risk window may emerge next year. What is copper foil? Why is it so critical? Copper foil is the "conductive skeleton" of the lithium battery anode, an extremely thin copper film only a fraction of the thickness of a human hair. It accounts for a modest share of battery costs (about 10%-15%), but even slight quality fluctuations can affect battery yield and safety. More importantly, copper foil supply is not a case of "having capacity means having product"—a plant may plan annual production of 100,000 mt, but the volume that can actually pass battery maker certification and be supplied steadily is often discounted. The supply-demand gap does exist, but pressure is limited this year In 2026, China's lithium battery copper foil demand is about 1.37 million mt, while actual stable supply is about 1.35 million mt, leaving a gap of about 20,000 mt (corresponding to the copper foil raw material needed for about 50 GWh of lithium battery cells). Against an estimated global lithium battery cell production of about 3,400 GWh in 2026, this figure is not large, and in the short term battery makers can still buffer through inventory, adding suppliers, and adjusting production schedules. Therefore, copper foil will not become a hard constraint on lithium battery production increases this year; the impact will be seen more in tight production schedules at leading suppliers, greater difficulty in placing last-minute orders, and longer delivery cycles for certain specifications. Looking further ahead, however, pressure will rise: the gap in 2027 is about 40,000 mt (corresponding to the copper foil raw material needed for about 100 GWh of lithium battery cells), and it may continue to widen in 2028. Copper foil demand growth is outpacing supply growth, and the situation will tighten further over time. AI copper foil is "distracting" attention, but has not yet stolen the race Recently, AI servers and high-speed communications have been booming, and processing fees for high-end electronic copper foil have surged to 200,000-300,000 yuan/mt, nearly 10 times that of ordinary lithium battery copper foil. This will attract leading copper foil makers to shift capital and equipment toward high-end products, but such production lines have high technical barriers and long certification cycles, so they cannot be converted at scale in the short term. In other words, AI copper foil will not immediately crowd out lithium battery copper foil capacity, but it will raise the "opportunity cost" of lithium battery capacity expansion—when copper foil makers make new investments, they will prioritize the more profitable high-end electronic copper foil. Key judgment: this year can hold, next year depends on positioning The impact of copper foil shortages on the battery industry is progressive. Stage one (this year): inventory and flexible procurement can still hold. Battery makers generally have stockpiles and can also adjust through multiple suppliers, so short-term production increases will not be significantly constrained. Stage two (next year and beyond): if new capacity does not keep pace and long-term contracts are not locked in early, production may indeed be affected. New production line certification takes time, and once the gap widens, spot procurement will struggle to find stable supply sources, and certain specifications may see "capacity exists, but no spot cargo" situations. Stage three (long term): upstream and downstream will become deeply bound. CATL and partners such as Huike will jointly build 400,000 mt of copper foil capacity over the next three years, signaling that battery leaders are shifting from "annual tenders" to "direct participation in plant construction." In the future, battery makers wanting to secure supply will likely need to provide funds, orders, and joint R&D in advance. Conclusion The structural shortage of lithium battery copper foil is already established, but in the short term it will not significantly limit battery production increases, as enterprise inventory and procurement flexibility still provide buffer room. The real test will come in 2027 and beyond: if copper foil capacity expansion progress falls short of expectations and battery makers have not locked in long-term orders and capacity in advance, a tight balance of "orders but no materials" may emerge starting in H2 next year, thereby affecting production release. In summary, the copper foil supply constraint has not yet become the core contradiction this year, but it is shifting from an "option" to a "must-answer question." Battery makers that position long-term contracts and capacity binding in advance will gain a clear supply chain flexibility advantage next year.

[SMM Analysis] US Refined Copper Tariff Uncertainty Returns—What Does It Mean for Global Copper Scrap?
[SMM Analysis] US Refined Copper Tariff Uncertainty Returns—What Does It Mean for Global Copper Scrap?
[SMM Analysis: US Refined Copper Tariff Uncertainty Returns—What Does It Mean for Global Copper Scrap?] US refined copper tariff uncertainty is reshaping global copper flows. If tariffs proceed, a wider COMEX-LME spread could draw more cathode into the US and support scrap demand elsewhere. If delayed or cancelled, the spread may narrow and weaken scrap payabilities. However, low global scrap inventories and tight VAT-invoiced supply in China make a sharp correction unlikely.

[SMM Analysis]Downstream Demand Improves Marginally, Non-Oriented Silicon Steel Prices to See Modest Gains in September
Monthly Review & Outlook: Downstream Demand Improves Marginally; Non-Oriented Silicon Steel Prices to See Only Modest Gains in September August Price Review Source: SMM Non-oriented silicon steel prices remained generally weak in August. Prices of mainstream grades edged lower across the board, with both high-grade and medium-low grade products under pressure. The monthly average price of benchmark grade B50A800 fluctuated at a low level. Although the supply-demand gap narrowed slightly in August, supply remained relatively loose. Lacking strong support from downstream demand, prices had limited upward momentum. The market consolidated at low levels overall; declines slowed, yet no clear rebound emerged. Fundamental Analysis Source: SMM Domestic output of non-oriented silicon steel fell month-on-month in August, a notable drop from July, as steel mills proactively cut production schedules. By grade mix, medium-low grades accounted for 66%, high grades 19%, and new-energy grades rose to 15%. Compared with July, the share of medium-low grades declined while new-energy grades increased, and high-grade share stayed stable. Production capacity continued shifting toward high-end products. Production scheduling for September retains divergent features: medium-low grades will rebound to 69%, high grades fall to 18%, and new-energy grades dip slightly to 14%. Steel mills plan to raise output of medium-low grades in September while trimming the proportion of high-grade production. Overall, August production cuts eased supply pressure to some extent, yet the rebound in medium-low grade output in September reflects steel mills’ improved market expectations for the month. Source: Public data, SMM Output of major domestic home appliance categories fell seasonally in July, with production of air conditioners, refrigerators, washing machines and color TVs retreating from earlier peaks. Monthly consumption of non-oriented silicon steel by the home appliance sector declined accordingly. By consumption breakdown, air conditioners represented 65% of silicon steel use in home appliances, making them the largest consumer; refrigerators, washing machines and color TVs accounted for 20%, 11% and 4% respectively. Total silicon steel consumption by home appliances dropped month-on-month in July, dragged down primarily by weaker air conditioner demand. China’s new-energy vehicle output stayed robust in July. Production of new-energy passenger and commercial vehicles maintained strong resilience, while output of conventional fuel vehicles remained relatively steady. The automotive sector is a core consumer of non-oriented silicon steel. In terms of consumption structure, new-energy passenger vehicles made up 75%, new-energy commercial vehicles 22%, and traditional vehicles only 3%. New-energy models have become the dominant source of automotive silicon steel consumption. Monthly silicon steel consumption by the auto sector edged up month-on-month in July. High production schedules for new-energy vehicles underpinned silicon steel demand and offset part of the home appliance demand slump. Nevertheless, incremental demand from automobiles was insufficient to fully counterbalance the decline in home appliances, leading to only limited overall improvement in downstream demand for non-oriented silicon steel. September Price Outlook Looking ahead to September 2026, on the supply side, planned output of non-oriented silicon steel in China is set to rise, with growth concentrated in medium-low grades. For one thing, the traditional off-season is drawing to a close; downstream orders for home appliance and motor manufacturers are expected to pick up, boosting steel mills’ willingness to produce. For another, leading producers including Baowu lifted base prices by RMB 50 per tonne for September, showing clear intentions to prop up and raise prices. This is expected to restore steel mill margins and support production. On the demand side for home appliances: production continued slowing in August. Most manufacturers scheduled high-temperature shutdowns and equipment maintenance in early August. Orders and sales were mixed. Air conditioners and refrigerators saw weaker orders and sales due to sluggish end-market demand. Washing machines entered their peak season, yet demand fell short of expectations. For the automotive sector, market performance is projected to be weak early in the month and strong later. In early August, offline sales were hampered by high temperatures, typhoons and other weather disruptions. Demand started to release from mid-August onward. Multiple new models launched by leading new-energy original equipment manufacturers (OEMs) were priced in line with consumer expectations, driving notable increases in store foot traffic and orders, marking a market recovery. On the cost side, September marks the traditional “Golden September” consumption peak. With hot and rainy weather abating, end-user project construction and downstream restocking demand are anticipated to improve marginally. Hot rolled coil prices are projected to trend higher in September. In summary, SMM forecasts that medium-low grade non-oriented silicon steel prices will trend upward amid volatility in September 2026, with moderate upside potential.
