• Did you know2024

  Dingsheng's aluminum rolling mills simultaneously produce: battery-grade cathode current collector foil (8 µm, 99.5%+ purity) that conducts electrons from lithium-ion battery cathodes in EV battery packs; electrolytic capacitor electrode foil (high-purity, etched to increase surface area) used in the power supply capacitors of every industrial motor drive, EV charger, and consumer electronics device; and pharmaceutical blister pack foil (20-25 µm) used to package virtually every pill and tablet dispensed globally. Three completely different regulatory and application worlds — electric vehicle batteries (UL, IEC, GB standards), electronic components (capacitor voltage/temperature ratings), and pharmaceutical packaging (FDA/EMA pharmaceutical packaging requirements) — all trace their aluminum input to the same Chinese precision rolling mills. A disruption in Chinese battery-grade aluminum foil supply (trade restriction, power curtailment, material shortage) would simultaneously affect global EV production, industrial electronics manufacturing, and pharmaceutical dispensing, because the same precision rolling capability and high-purity aluminum feedstock serve all three markets.

• Concentration2024

  Battery-grade aluminum foil production is concentrated in China at approximately 70-75% of global capacity, with Chinese manufacturers (Dingsheng, Nanshan Aluminium, Shengda Aluminium, Alcha International) dominating the supply for global EV battery manufacturers. Non-Chinese battery foil capacity is limited — Novelis (Indian/American ownership, US and European plants), Lotte Aluminium (Korea), and a few European producers together supply most non-Chinese demand, but at lower capacity and generally higher cost than Chinese producers. The EV battery supply chain's cathode current collector is therefore structurally dependent on Chinese aluminum rolling capacity in a way analogous to China's earlier dominance in rare earth processing: the raw material (aluminum) is global, but the precision conversion capability (battery-grade ultra-thin rolling) is concentrated in China. US and European battery manufacturers sourcing outside China face a meaningful cost penalty (15-25% price premium for non-Chinese foil) that directly affects battery pack economics and EV pricing. A Western trade restriction on Chinese battery foil would force US and European battery manufacturers to either absorb significantly higher foil costs or invest billions in new non-Chinese rolling capacity that takes 3-5 years to qualify and reach volume.

• Origin2024

  Dingsheng New Materials (鼎盛新材科技股份有限公司) grew from China's general aluminum rolling industry into a specialized battery materials supplier through the expansion of China's EV industry. The company's trajectory reflects a broader pattern in Chinese advanced materials: commodity aluminum rolling capability → precision foil rolling for electronics → ultra-precision battery-grade foil as the EV market created enormous demand for high-purity thin foil. Dingsheng invested heavily in ultra-thin rolling capacity (capable of achieving 6-8 µm at high speed and width) as Chinese battery manufacturers (CATL, BYD, CALB) scaled from niche to global dominance between 2015 and 2025. The company's rapid growth was financed in part by the strategic importance Chinese industrial policy placed on battery supply chain localization — battery-grade aluminum foil was identified as a critical material for China's EV ambitions, and domestic producers like Dingsheng received preferential financing, land, and power tariff conditions to scale. The result: China now produces approximately 75% of global battery-grade aluminum foil, with Dingsheng as a top-3 player.
