Synthetic Graphite Anode Material

BTR New Material Group Co., Ltd. (Shenzhen; SZSE: 835185; ~¥13B revenue 2023) is the world's largest producer of lithium-ion battery anode materials by volume, overtaking Shanshan Corporation around 2020-2021. BTR produces both synthetic graphite anode material (dominant product, ~70% of its anode volume) and natural graphite anode material (~30%). Its synthetic graphite anode is made by graphitizing petroleum coke or coal tar pitch precursors at ~3000°C in Acheson electric resistance furnaces, producing high-purity (99.9%+) spheroidized graphite with superior electrochemical performance versus natural graphite. BTR's customers include CATL, BYD, LG Energy Solution, Panasonic, Samsung SDI, and SK On. BTR operates multiple production bases across China (Shenzhen Bao'an, Guizhou, Shandong, Ningde) and is expanding into localized overseas production (BTR Korea JV, BTR Germany study). Estimated ~25% global synthetic graphite anode market share in 2023.

Shanshan Corporation (Ningbo; SSE: 600884) is one of China's oldest and largest battery anode material producers, founded in 1992 as the first commercial synthetic graphite anode manufacturer in China. Shanshan was formerly the world's #1 anode producer before BTR overtook it by volume. Shanshan's anode division (Ningbo Shanshan Co.) operates under the Shanshan Group holding structure. Synthetic graphite anode is produced at Shanshan's Changsha (Hunan), Baotou (Inner Mongolia), and Ningbo facilities. Shanshan is also a significant cathode material producer (NMC). Estimated ~18% global synthetic graphite anode market share in 2023. Major customers: CATL, Panasonic, AESC.

Putailai New Energy Technology Co., Ltd. (Nanchang, Jiangxi; SZSE: 688567; formerly known through its Jiangxi Zichen subsidiary) is the third-largest synthetic graphite anode producer in China by volume. Putailai operates large-scale Acheson furnace graphitization capacity at its Jiangxi and Sichuan production bases. Key differentiation: Putailai also produces anode manufacturing equipment (graphitization furnaces), giving it vertical integration advantages. Estimated ~13% global synthetic graphite anode market share in 2023. Customers include CATL, BYD, SVOLT. The company's Jiangxi Zichen brand is widely recognized in Chinese battery supply chains.

CNGR Advanced Material Co., Ltd. (Changsha, Hunan; SZSE: 300919) is a diversified battery materials producer that includes synthetic graphite anode material among its product lines, though CNGR is better known as a leading nickel-cobalt precursor and ternary cathode material producer. Its anode materials division contributes ~5-7% of global synthetic graphite anode supply. Customers include CATL, LGES, Samsung SDI. CNGR has also built significant overseas operations in Indonesia (nickel feedstock) and Finland (cathode precursor for European supply chains).

Resonac Holdings K.K. (Tokyo; TSE: 4004; formed 2023 by merger of Showa Denko K.K. and Hitachi Chemical Company Ltd.) is Japan's second-largest ABF substrate film producer after Ajinomoto Fine-Techno, and major semiconductor materials company. Resonac's semiconductor materials division produces ABF-equivalent build-up films under the brand name 'MCL' (Multilayer build-up resin for Core-Less substrates). The merger creating Resonac combined Showa Denko (industrial chemicals, graphite electrodes, specialty gases) with Hitachi Chemical (now Resonac Holdings; adhesives, printed circuit board materials, semiconductor packaging resins) — creating a $8B+ semiconductor materials company directly competing with Ajinomoto in FC-BGA substrates. Showa Denko had itself absorbed Hitachi Chemical in 2021 and rebranded to Resonac in 2023.

Novonix Ltd. (Halifax, Nova Scotia; ASX/Nasdaq: NVX; formerly known through its Dalhousie University spinout origins) is a North American synthetic graphite anode startup operating the only commercial-scale synthetic graphite anode production facility in North America. Novonix's Aiken, South Carolina facility (targeting 10,000 tonnes/year by 2025) uses a proprietary all-dry (no wet slurry) synthesis process that is significantly less energy-intensive than traditional Acheson furnace graphitization, and avoids the need for high-temperature furnaces sourced from China. Novonix received a US$103 million DOE Office of Manufacturing and Energy Supply Chains (MESC) grant in 2022 to scale U.S. synthetic graphite production. Customers include Phillips 66 (strategic investor), Samsung SDI (equity investor and offtake agreement). Novonix also operates a battery research services division in Halifax and a materials characterization business.

Group14 Technologies (Woodinville, Washington; private) produces silicon-carbon anode material (SCC55, a scaffold-based silicon-carbon composite) rather than pure synthetic graphite — but is directly substitutable for synthetic graphite as a lithium-ion battery anode and represents the primary technological threat to China's synthetic graphite dominance. Group14's BAM (Battery Active Material) facility in Moses Lake, Washington produces silicon-carbon anode using polysilane precursors and a proprietary hard carbon scaffold (manufactured from sustainable biomass sources). Group14 received a US$100 million DOE DERA grant in 2022. Investors include SK Inc. (South Korea), Lightrock, and OVH. BAM-1 (Moses Lake) produces ~2,000 tonnes/year; Group14 is scaling to BAM-2 targeting 120,000 tonnes. Silicon-carbon anodes can hold ~10x more lithium per gram than graphite but historically suffered from volume expansion; Group14's scaffold design addresses this.
