[SMM Separator Weekly Review] Supply-demand balance remains tight, coated products poised for price hikes

[SMM Analysis] Separator Market Prices Remain Stable Overall

Separator prices continued to consolidate this week, with quotation ranges for all specifications largely unchanged from last week. In terms of specific quotations, prices for high-end wet-process separator products remained firm: 5μm (5μ+2μ) was quoted at 1.57-1.87 yuan/m², mainstream quotations for 7μm (7μ+2μ) stood at 1.14-1.337 yuan/m², and 9μm (9μ+3μ) was quoted at 1.135-1.29 yuan/m². Prices are expected to edge up next week, mainly for 5μm+2μm coated and 7μm+2μm+3μm coated products. The upward momentum still stems from supply and demand. Data shows that separator production growth has remained below terminal production schedule growth, and the gap has not narrowed. On the demand side, there is also a structural shift: as capacity for large battery cells comes online, battery cell manufacturers are accelerating the transition from 7μm to 5μm. The 5μm specification places higher demands on production line yield and equipment, making effective supply even tighter than nominal capacity, and these products have the strongest pricing power. In our assessment, the price increase next week will most likely be led by 5μm+2μm, with 7μm+2μm+3μm following suit. The trend of switching to 5μm is unlikely to reverse in the short term, and the supply-demand tightness for high-end coated products will remain greater than that for base film, leaving further room for price increases.

Per MIIT data and customs statistics, China exported 3.69 billion lithium-ion batteries in Jan-Aug 2026, up 22.9% YoY. Value-added output of the electronics manufacturing industry grew 15.7% YoY, with revenue up 20.1% to RMB 12.8 trillion and total profit up 110% to RMB 847.5 billion. The strong battery exports reflect sustained overseas demand for power and energy storage batteries.

[SMM Analysis: Solid-State Battery Next Decade Series, 9 of 9: A Brand-New Track, Not a "Simple Sequel" to Liquid Lithium Batteries] The industrialisation of solid-state batteries is not a "capacity replication + minor technical adjustment" of liquid lithium batteries, but a systematic shift from resource logic, chemical logic, and material logic to patent logic. The most common mistake in understanding solid-state batteries through the framework of liquid lithium batteries is treating "planned capacity" as "effective supply," treating "technical routes" as "settled answers," and treating "first-mover advantage" as "ultimate victory.
