[SMM Analysis] Separator Market Prices Remain Stable Overall

The separator market remained largely stable this week. In terms of specific quotations, high-end wet-process separator prices held firm: 5μm (5μ+2μ) was quoted at 1.57-1.87 yuan/m², 7μm (7μ+2μ) mainstream quotations were 1.14-1.337 yuan/m², and 9μm (9μ+3μ) was quoted at 1.135-1.29 yuan/m². Supply side, newly added capacity in July was still driven mainly by upgrading existing production lines, leading to a slow growth pace. Top-tier players had accepted current quotation levels, and overall prices were expected to remain stable in July. However, divergence emerged across different products: base film prices saw limited gains, mainly because second- and third-tier enterprises maintained a relatively competitive pricing strategy; prices for coated products were relatively firm due to tight supply-demand conditions. From a supply-demand fundamental perspective, the separator market was still in a state of undersupply. End-use production schedules in July grew approximately 7% MoM, with both the EV and ESS sectors staying highly buoyant. Driven by this, separator production in July rose 3.71% MoM, but the production growth rate still lagged end-use demand growth, keeping a supply-demand gap in place. The industry’s overall operating rate stayed above 80%. Battery cell enterprises not only locked in mainstream separator capacity, but some long-term supply agreements further extended to second- and third-tier separator enterprises, pushing the industry’s overall capacity utilization rate to stay high. After a previous round of price adjustments took effect, the market entered a new price-implementation phase. Separator prices are expected to stay largely stable in the short term; the subsequent trend will depend on the pace of new capacity release and downstream acceptance of price increases.

[SMM Cobalt Morning Meeting Summary] Raw Material Prices Pulled Back, Ternary Cathode Material Fell Under Pressure

SMM Cobalt Morning Briefing: This week, the cobalt industry chain remained in the doldrums overall, with market transactions generally sluggish. Refined cobalt returned to grinding lower, and despite smelters raising EXW prices to 390,000 yuan/mt, downstream only maintained just-in-time procurement, affected by the summer break and traditional consumption off-season; cobalt intermediate product prices were temporarily stable, while the disagreement between miners holding prices firm and smelters’ low-price procurement remained significant. Demand for cobalt sulphate, cobalt chloride, and Co3O4 all saw no significant improvement, with downstream inventories ample, and restocking may have to wait until after August. Mainstream cobalt powder transaction prices fell to 460,000 yuan/mt, with some low prices reaching 440,000–450,000 yuan/mt. The market remained in a weak stage of seeking a bottom.

[SMM Cobalt Lithium Morning Meeting Summary] Raw Material Prices Under Pressure; Battery Production Schedules Continue to Grow

[SMM Cobalt-Lithium Morning Briefing: This week, prices in the new energy industry chain continued to diverge. The lithium industry chain was generally weak. The transaction center of lithium ore shifted lower alongside lithium chemical prices, and lithium carbonate fell to around 150,000 yuan/mt. Downstream firms bought the dip at low price levels, but upstream producers held prices firm and held back from selling, intensifying the market tug-of-war. Lithium hydroxide transaction prices declined in tandem, and overall trading remained sluggish. In the cobalt industry chain, demand was weak. Refined cobalt, cobalt sulphate, and cobalt chloride all lacked effective transaction support, while prices of intermediate products and Co3O4 temporarily held steady. Nickel sulphate inventory continued to decline, but downstream stockpiling willingness was insufficient, and prices still faced pressure.]
