Cathode active material (NMC/LFP/NCA)

Japanese non-ferrous metals and mining company (TSE: 5713, HQ Tokyo); one of the world's oldest mining enterprises — its Besshi Copper Mine in Ehime Prefecture operated from 1691 to 1973, making Sumitomo Metal Mining older than the United States. Today SMM is a leading producer of nickel sulfate for Li-ion battery precursors (NMC/NCA pCAM). SMM operates Coral Bay Nickel Corporation (CBNC) and Taganito HPAL Nickel Corporation (THPAL) in the Philippines — high-pressure acid leach plants that process Philippine laterite nickel ore into mixed sulfide precipitate (MSP), which is then refined into nickel sulfate at the Niihama Nickel Refinery in Ehime Prefecture, Japan. SMM's integrated laterite-to-sulfate pathway (Philippines HPAL → Japan refinery) is one of the most established non-Chinese nickel sulfate supply chains for Korean and Japanese battery manufacturers (Toyota-Panasonic joint venture PPES; Panasonic Energy). SMM is also the world's leading producer of nickel hydroxide for NiMH hybrid vehicle batteries.

Umicore N.V. (Brussels; Euronext: UMI; ~$4B revenue) is a global specialty materials and recycling company whose Hoboken, Belgium precious metals refinery is a major European indium producer. Umicore recovers indium from complex lead/copper metallurgical residues and dusts at its Hoboken smelter near Antwerp — a unique secondary-metallurgy process that differs from the primary zinc-smelter byproduct route used by most producers. Umicore's indium capacity is ~50 tonnes/year, representing ~3% of global output and making Belgium a meaningful EU indium source. Umicore is also the world's leading recycler of battery materials (cobalt, lithium) and catalysts; indium recovery at Hoboken is one component of a broader complex metals recovery operation. Umicore's Hoboken plant is one of the most technically sophisticated non-ferrous secondary smelters in the world.

South Korean cathode active material company (KOSDAQ: 247540, HQ Cheongju, North Chungcheong; EcoPro Group subsidiary); world's second-largest NCA cathode producer and a significant NMC producer for Korean battery makers. EcoPro BM supplies Samsung SDI (which uses EcoPro NCA for its cylindrical cells in BMW and other EV makers) and SK On. EcoPro BM's single-crystal NMC811 and NCA products enable premium battery performance — particularly for the cylindrical 21700 and 46xx format cells used in high-performance EVs. EcoPro Group also includes EcoPro Materials (battery recycling) and EcoPro Innovation — building a Korean circular CAM ecosystem. EcoPro BM's stock price rose ~600% in 2021-2022 as Korean battery material demand surged, then fell ~70% in 2023 as lithium prices collapsed and EV growth decelerated — illustrating the extreme cyclicality of battery material stocks.

German chemical company (XETRA: BAS, HQ Ludwigshafen; ~€69B revenue); Battery Materials division produces NMC cathode active material at Schwarzheide, Brandenburg (former East Germany; site of a Nazi-era synthetic oil refinery, now a major BASF specialty chemicals site). BASF's Schwarzheide plant produces NMC622, NMC811, and high-voltage NMC cathode active materials for European and Korean battery manufacturers. BASF is the largest European-headquartered CAM producer. BASF also holds a stake in Norilsk Nickel (Nornickel) — Russia's largest mining company — through its Catalysts division which uses Nornickel palladium and rhodium in automotive catalysts: the same BASF that makes NMC cathode material also sources precious metal catalysts from the Russian company whose nickel and cobalt feed into battery supply chains. BASF Battery Materials won a production contract with BMW for its Neue Klasse EV battery cathode — one of the most important European CAM contracts of the 2020s.

Chinese battery cathode material company (SZSE: 300073, HQ Beijing); one of China's largest LFP (lithium iron phosphate) cathode material producers alongside Yunnan Yongkang Energy, Hunan Shenghua A&P, and others. Beijing Easpring produces LFP cathode for BYD's Blade Battery and for multiple Chinese and export battery manufacturers. LFP cathode — which eliminates cobalt (the ethically problematic DRC mineral) and reduces nickel dependence while offering superior thermal stability and cycle life — has undergone a renaissance since 2020: Tesla adopted LFP for its standard range vehicles in 2021; BYD's entire lineup uses BYD-manufactured LFP. LFP's re-emergence after a decade of being considered 'old technology' is driven by its lower cost (no cobalt), safety profile (no thermal runaway), and cycle life improvements from single-crystal manufacturing advances.

World's largest single STPP producer; 20-25% of global STPP market; 60,000 MT/year dedicated STPP capacity. China contributes ~80% of global STPP production, and Hubei Xingfa is the dominant Chinese producer. Also produces phosphoric acid, sodium hexametaphosphate (SHMP), and other phosphorus chemicals. Hubei province (also home to Three Gorges Dam) is a major Chinese chemical hub. Listed on Shanghai Stock Exchange. Serves food, detergent, water treatment, and industrial markets globally.
