Essential Anhui EV Battery Supply Chain Resources

Anhui Province (Ānhuī Shěng, 安徽省) has emerged as a pivotal hub in China’s electric vehicle (EV) battery supply chain. With major production bases clustered in Hefei (Héféi, 合肥), Wuhu (Wúhú, 芜湖), and Ma’anshan (Mǎ’ānshān, 马鞍山), the province hosts an integrated ecosystem spanning raw material refining, battery component manufacturing, cell assembly, testing, and end-of-life recycling. This article presents a curated resource guide for investors, procurement professionals, and industry analysts seeking to understand and engage with Anhui’s battery supply chain.

Lithium and Raw Material Suppliers

Anhui is home to several key lithium processing and raw material firms that supply the broader battery manufacturing chain. Gotion High-tech (Guóxuān Gāokē, 国轩高科), headquartered in Hefei, is one of China’s largest power battery manufacturers and also operates upstream lithium refining and precursor production lines. Another major player is Tianqi Lithium (Tiānqí Lǐyè, 天齐锂业), which maintains processing and distribution operations in the province. These companies supply lithium carbonate and lithium hydroxide — critical precursors for cathode active materials — to battery cell producers across Anhui and beyond.

In addition to lithium, Anhui has significant manganese and cobalt processing capacity. The Hefei-based branch of Huayou Cobalt (Huáyǒu Gǔyè, 华友钴业) handles cobalt refining and ternary precursor production, serving the NCM (nickel-cobalt-manganese) cathode supply chain that dominates China’s EV battery output.

Cathode and Anode Material Producers

Cathode active materials are the most value-intensive component of a lithium-ion battery, accounting for roughly 30-40% of total cell cost. Anhui hosts a dense concentration of cathode producers. Easpring Material Technology (Dàngshēng Cáiliào, 当升材料) operates a major production base in Hefei focusing on high-nickel NCM cathode materials. Shanshan Advanced Materials (Shānshān Gāojí Cáiliào, 杉杉高级材料), a national leader in both cathode and anode materials, runs a significant anode graphite facility in Anhui’s Chuzhou (Chúzhōu, 滁州) industrial zone.

For anode materials, BTR New Material (Běitèxīn Cáiliào, 贝特新材料) operates large-scale natural and artificial graphite production lines in Wuhu. The company supplies major battery makers including CATL (Níngdé Shídài, 宁德时代) and BYD (Bǐyàdí, 比亚迪). Silicon-carbon composite anode capacity is also expanding, with Shanghai Putailai New Energy Technology (Pǔtàilái, 璞泰来) commissioning a next-generation anode plant in Ma’anshan in 2024.

Separator Manufacturers

Battery separators — the porous membranes that prevent short circuits while enabling ion transport — are a specialized segment where Anhui has carved out a strong position. Senior Technology Material (Xīngyuán Cáiliào, 星源材料), one of China’s “Big Three” separator makers (alongside Yunnan Energy and ShanghaiPutailai), has its main production base in Hefei. The company manufactures both wet-process and dry-process separators suitable for LFP (lithium iron phosphate) and NCM chemistries.

Another notable manufacturer is ZIM (Zhōngxiàng Xīn Cáiliào, 中翔新材料), which operates a biaxially-oriented polypropylene (BOPP) separator line in Ma’anshan with an annual capacity of 600 million square meters. These separator plants serve not only the Chinese domestic market but also export to South Korean and Japanese battery makers.

Electrolyte Companies

Electrolyte production in Anhui is led by Tinci Materials (Tiāncì Cáiliào, 天赐材料), the world’s largest lithium-ion battery electrolyte manufacturer by volume. Tinci operates a large-scale electrolyte plant in Hefei that produces formulations for LFP, NCM, and solid-state precursor electrolytes. The company also manufactures lithium hexafluorophosphate (LiPF₆, Liùfú Línsuān Lǐ, 六氟磷酸锂), the key electrolyte salt, at the same site — a vertical integration strategy that reduces cost and ensures supply stability.

Guangzhou Tinci Materials’ Anhui subsidiary has a combined annual electrolyte production capacity exceeding 200,000 tonnes as of early 2025. A secondary electrolyte blender, Capchem Technology (Xīnzhōubāng Gǔfèn, 新宙邦股份), operates a smaller but highly automated facility in Wuhu focused on high-voltage electrolyte formulations for EV applications requiring fast charging.

Key Battery and Component Manufacturers — Data Table

The following table summarizes major battery supply chain companies operating in Anhui Province, including their primary products, locations, and reported capacities.

Testing and Certification Laboratories

Anhui’s battery ecosystem is supported by a growing network of testing and certification labs. The Hefei Institute of Physical Science, part of the Chinese Academy of Sciences (CAS, Zhōngguó Kēxuéyuàn, 中国科学院), operates a battery testing and characterization facility that provides cycle life testing, thermal runaway analysis, and material purity verification for companies across the province. This lab is certified under the China National Accreditation Service for Conformity Assessment (CNAS).

In the private sector, TÜV Rheinland (a German testing giant) opened a battery safety testing center in Hefei in 2023, offering UN 38.3 transport testing, UL/CE certification, and performance benchmarking. The facility is strategically located near Gotion High-tech’s headquarters, enabling rapid certification turnaround for battery packs destined for export markets. Additionally, the Anhui Provincial Product Quality Supervision and Inspection Institute (Ānhuī Shěng Chǎnpǐn Zhìliàng Jiāndū Jiǎnyàn Yánjiūyuàn, 安徽省产品质量监督检验研究院) provides local mandatory testing services for batteries sold within China.

Battery Recycling Facilities

End-of-life battery recycling is a rapidly growing segment of Anhui’s supply chain, driven by China’s extended producer responsibility regulations and the coming wave of retired EV batteries. Gotion High-tech operates one of the province’s largest battery recycling facilities in Hefei, with a processing capacity of 50,000 tonnes per year. The plant uses a combined hydrometallurgical and pyrometallurgical process to recover lithium, nickel, cobalt, and manganese from spent LFP and NCM batteries, achieving recovery rates above 95% for cobalt and nickel.

Another major recycler is Brunp Recycling (Bāngpǔ Xúnhuán, 邦普循环), a CATL subsidiary that operates a large recycling campus in Wuhu. Brunp’s Anhui facility processes both production scrap (from battery cell manufacturing) and end-of-life battery packs, feeding recovered materials back into the cathode precursor supply chain. The provincial government of Anhui has designated EV battery recycling as a strategic emerging industry, offering tax incentives and land subsidies for new recycling facilities in designated industrial parks near Hefei and Wuhu.

Strategic Outlook

Anhui’s EV battery supply chain resources are distinguished by their geographic concentration and vertical integration. Within a 150-kilometer radius of Hefei, an investor can find lithium refining, cathode and anode production, separator manufacturing, electrolyte blending, cell assembly, testing laboratories, and recycling — a level of supply chain density rivaled only by the Ningde-Fuzhou corridor in Fujian Province. For companies looking to source battery materials or establish joint ventures in China, Anhui offers logistical advantages (the Yangtze River port system, high-speed rail, and proximity to Shanghai’s export terminals), a skilled technical workforce from local universities including the University of Science and Technology of China (USTC, Zhōngguó Kēxué Jìshù Dàxué, 中国科学技术大学), and proactive local government support.

As the global EV market continues its expansion, Anhui’s battery supply chain is poised to play an increasingly central role — not only as a manufacturing base for China’s domestic EV industry but as an export hub for battery materials and components serving markets in Europe, Southeast Asia, and the Americas.
