EV Update: CATL Anhui Phase III Breaks Ground — Supply Chain Impact
Event Overview
In September 2026, CATL (宁德时代, Níngdé Shídài) broke ground on Phase III of its Anhui battery manufacturing base in Feixi County (肥西县, Féixī Xiàn), Hefei. The CNY 6.8 billion expansion will add 25 GWh of annual battery cell production capacity, bringing CATL Anhui’s total capacity to 65 GWh and making it CATL’s second-largest production base outside of its Ningde headquarters in Fujian Province.
Phase III is dedicated to the production of Qilin 3.0 battery cells — CATL’s next-generation CTP (cell-to-pack) technology that achieves energy density of 280 Wh/kg at the pack level and supports 6C ultra-fast charging (0-80% in 8 minutes). The facility will also have a flexible production line capable of switching between LFP (lithium iron phosphate, 磷酸铁锂, línsuān tiě lǐ), NCM (nickel-cobalt-manganese, 镍钴锰, niè gǔ měng), and LMFP (lithium manganese iron phosphate, 磷酸锰铁锂, línsuān měng tiě lǐ) chemistries, with changeover time of under 72 hours.
For supply chain investors and material suppliers, Phase III represents a substantial demand injection that ripples through multiple upstream industries: cathode materials, anode materials, electrolytes, separators, current collectors, and production equipment. This article analyzes the supply chain impact of Phase III across three horizons: immediate (construction phase 2026-2027), ramp-up (production qualification 2027-2028), and steady-state (full production 2028+).
Phase III Facility Specifications
| Parameter | Phase I & II (Existing) | Phase III (New) | Combined |
|---|---|---|---|
| Capacity (GWh/year) | 40 | 25 | 65 |
| Investment (CNY) | 12.5 billion (Phase I+II) | 6.8 billion | 19.3 billion |
| Floor Area (m²) | 320,000 | 210,000 | 530,000 |
| Primary Chemistry | NCM 811, LFP | Qilin 3.0 (NCM/LFP/LMFP flexible) | Multi-chemistry |
| Cell Format | Prismatic 305Ah, 320Ah | Prismatic 385Ah (Qilin 3.0) | Dual-format capable |
| Production Lines | 16 lines | 10 lines (flexible chemistry) | 26 lines |
| Workers (projected) | 4,500 | 3,200 | 7,700 |
| Primary Customers | NIO, Tesla Shanghai, Chery | NIO (NT 3.0), VW Anhui, BMW | 3-4 major OEM anchor customers |
| Automation Level | 75% automated | 90% automated (lights-out capable) | 82% automated (blended) |
| Estimated Completion | Operational | Q1 2028 | N/A |
The Phase III facility is designed to Industry 4.0 standards with 90% automation, including AI-powered electrode inspection, robotic cell stacking, and fully automated formation and aging processes. The lights-out capability, while initially applied only to the electrode coating and cell assembly stages, will reduce per-Wh labor costs by approximately 30% compared to Phase II.
Construction Phase Impact (2026-2027)
Construction Materials and Equipment
The 210,000 m² Phase III construction will consume substantial quantities of industrial construction materials over a 15-month build period:
- Steel reinforcement (钢筋, gāngjīn): Estimated 45,000-55,000 tonnes, primarily sourced from Ma’anshan Iron & Steel (马钢, Mǎ Gāng), Anhui’s largest steel producer. The Ma’anshan-Wuhu-Hefei steel supply chain benefits directly from Phase III demand.
- Industrial concrete (工业混凝土, gōngyè hùnníngtǔ): 250,000-300,000 m³ of high-strength concrete, much of it supplied by Anhui-based ready-mix producers in Hefei and Lujiang.
- Cleanroom and dry room construction: The 25,000 m² dry room (dew point -50°C) requires specialized dehumidification systems from suppliers such as Munters (Sweden) or Cotes (Denmark), along with domestic alternatives like Chinalling (中国联领, Zhōngguó Liánlǐng).
- HVAC and environmental control: The facility requires 12 industrial-grade HVAC systems with precise temperature (±0.5°C) and humidity (±2% RH) control. Foreign and domestic environmental control contractors are competing for this segment.
- Power infrastructure: Phase III requires 80 MW of connected electrical capacity, including two new 110 kV substations and battery-grade power conditioning equipment. State Grid Anhui and local power equipment suppliers are key beneficiaries.
Production Equipment Supply Chain (2027-2028)
The equipment procurement phase, which begins approximately 6 months into construction and extends through commissioning, represents the highest-value supply chain opportunity of Phase III. CATL’s equipment procurement for a 25 GWh flexible-chemistry line is estimated at CNY 2.5-3.5 billion, distributed across the following categories:
| Equipment Category | Estimated Spend (CNY) | Share of Total Equipment TAM | Anhui-Based Suppliers | Foreign/Coastal Competition |
|---|---|---|---|---|
| Electrode coating & drying lines | 600-900 million | 24-26% | Limited (1-2 small Anhui makers) | Lead: Yinghe Technology (赢合科技, Shenzhen), Wuxi Lead (先导智能, Wuxi), Manz (Germany) |
| Cell stacking & winding machines | 400-600 million | 16-17% | None currently qualified | Lead: Wuxi Lead, Shenzhen Yinghe, Hirano Tecseed (Japan) |
| Formation & aging systems | 350-500 million | 14-15% | Hefei-based formation equipment start-ups emerging | Lead: Wuxi Lead, Hangke Technology (杭可科技, Hangzhou), PNE Solution (Korea) |
| Calendar & slitting machines | 200-350 million | 8-10% | Limited capability | Lead: Shenzhen Yinghe, Wuxi Lead, Komiyama (Japan) |
| Battery testing & inspection | 250-400 million | 10-12% | USTC spin-off incubation candidates | Lead: Wuxi Lead, Sieyuan (思源电气, Shanghai), Chroma (Taiwan) |
| Material handling & logistics automation | 200-300 million | 8-9% | Hefei-based AGV/AMR makers (e.g., Hefei CAS-Harvest) | Lead: Geek+ (极智嘉, Beijing), GreyOrange (India) |
| Dry room & environmental equipment | 200-300 million | 8-9% | Chinalling (Jiangsu-based, Anhui-adjacent) | Lead: Munters (Sweden), Cotes (Denmark) |
| Plant auxiliary (boilers, chillers, compressed air) | 100-150 million | 4-5% | Anhui-based industrial equipment suppliers | Lead: Multiple domestic and foreign suppliers |
The key takeaway for Anhui-based equipment suppliers is sobering: Anhui currently captures less than 10% of the battery production equipment spend within its own borders. The dominant equipment suppliers are headquartered in Shenzhen (Yinghe Technology), Wuxi (Wuxi Lead), or abroad (Manz Germany, Hirano Japan). However, the Phase III ramp creates a window of opportunity for local equipment suppliers to qualify during the next 18-24 months, particularly in formation and aging systems, material handling automation, and testing and inspection — segments where Anhui-based firms are emerging or have credible plans.
Steady-State Material Demand (2028+)
Once Phase III reaches steady-state production of 25 GWh annually, it will consume significant quantities of battery materials. At average cell energy density of 260-280 Wh/kg, 25 GWh translates to approximately 89,000-96,000 tonnes of finished cells per year. The material breakdown is as follows:
| Raw Material | Annual Consumption (25 GWh, tonnes) | Anhui Supply Capability | Supply Gap |
|---|---|---|---|
| Lithium carbonate (LCE equivalent) | 17,000-19,000 | Minimal (~500 t from pilot operations) | Large — sourced from Sichuan, Qinghai, or imported |
| Nickel sulfate (NiSO₄·6H₂O) | 9,000-11,000 (NCM lines only) | Moderate (~3,000 t from Tongling smelters) | Growing — new capacity being planned in Tongling |
| Manganese sulfate (MnSO₄) | 2,000-3,000 | Strong (~8,000 t from Anhui-based producers) | None — Anhui is a net exporter of Mn-based materials |
| Cobalt sulfate (CoSO₄·7H₂O) | 1,000-1,500 | Minimal (~100 t) | Large — sourced from DRC via Zhejiang or Fujian |
| Graphite anode (人造石墨) | 10,000-12,000 | Limited (~1,000 t) | Large — sourced from Hunan or Inner Mongolia |
| Electrolyte (电解液) | 7,000-8,500 | Moderate (~2,500 t from Hefei-based mixers) | Growing — Tinci Materials (天赐材料) and others considering Anhui plant |
| Separator (隔膜) | 35-45 million m² | Limited (~5 million m² from pilot lines) | Large — sourced from Shenzhen Senior (星源材质) or Yunnan Enjie (恩捷股份) |
| Copper foil (铜箔) | 5,500-6,500 | Moderate (~1,500 t from Tongling-based foil makers) | Moderate — under expansion in Tongling, potential to close by 2029 |
| Aluminum foil (铝箔) | 3,500-4,500 | Moderate (~1,200 t) | Moderate — Anhui-based foil producers scaling up |
The material supply analysis reveals a clear pattern: Anhui has strong capability in manganese-based materials and growing capacity in copper foil, but faces significant gaps in lithium resources, cobalt, graphite, and separator production. These gaps represent investment opportunities for upstream material producers. For suppliers of electrolyte, separator, and copper foil, establishing Anhui production capacity within the next 2-3 years would position them to serve not only CATL Phase III but also the broader Anhui battery ecosystem (Gotion, SVOLT, BYD FinDreams) with combined demand exceeding 100 GWh.
Supply Chain Implications for Key Segments
Cathode Precursor and Active Material Producers
Phase III’s flexible chemistry lines (LFP, NCM, LMFP) mean that cathode material demand fluctuates based on market conditions. This makes supply contracts more complex — suppliers must be able to switch between LFP and NCM precursor production on short notice. The LMFP chemistry, in particular, is a newer technology that requires specialized co-precipitation processes. Anhui-based cathode material producers who invest in LMFP precursor capability now will have a first-mover advantage when CATL’s LMFP lines ramp up.
Anode Material and Graphite Suppliers
Phase III’s Qilin 3.0 cells require high-energy-density graphite anodes with specific capacity >360 mAh/g, achieved through advanced coating and doping processes. The current anode supply chain is dominated by producers in Hunan (BTR New Energy, 贝特瑞) and Inner Mongolia (Shanshan, 杉杉股份). Given the value-to-weight ratio of anode materials, establishing a Hefei-area production base would reduce logistics costs and strengthen supplier relationships with CATL Anhui.
Logistics and Warehousing
Phase III is expected to generate approximately 1,500-2,000 truckloads of inbound raw materials and 800-1,200 truckloads of outbound finished cells per month at steady state. This volume creates demand for:
- Warehousing (仓储, cāngchǔ): 30,000-50,000 m² of temperature-controlled warehouse space within 30 km of the Feixi County facility for just-in-time material supply.
- Specialized battery logistics: DG-certified (dangerous goods) semi-trailers and containers for cell and battery pack transport. Anhui currently has limited certified capacity.
- Port and rail connectivity: Most of Phase III’s production will serve NIO’s NeoPark (20 km east) and Volkswagen Anhui (15 km south), but export-oriented cells will move via the Hefei-Ningbo rail freight service, which is being expanded to handle 400+ TEUs per week by 2028.
Conclusion
CATL Anhui Phase III is the largest single battery production investment in Anhui Province to date, and its supply chain implications ripple across construction materials, production equipment, raw materials, and logistics services. The analysis reveals both strengths and gaps in Anhui’s current battery supply chain ecosystem:
Strengths: Anhui has existing capability in manganese-based materials, copper foil production (via Tongling’s copper cluster), construction materials (via Ma’anshan steel and Hefei concrete), and emerging capability in material handling automation.
Gaps (investment opportunities): Anhui has significant gaps in battery production equipment (Anhui captures <10% of equipment spend), lithium raw materials, cathode precursor production, separator manufacturing, and specialized battery logistics. Each of these gaps represents a CNY 100 million+ investment opportunity for suppliers who move quickly.
The Phase III timeline — completion by Q1 2028 — gives suppliers an 18-24 month window to establish local capability, qualify CATL’s supplier certification process, and position themselves for Phase III steady-state supply contracts. Given that CATL typically signs 3-5 year supply agreements for raw materials and consumables, suppliers who enter the qualification process in 2026-2027 will secure positions that persist through 2031-2033.
