Lithium Hydroxide (Battery Grade)

Albemarle Corporation (NYSE: ALB; HQ Charlotte, NC; ~$6B revenue 2023) is one of the world's largest lithium producers and the leading US-headquartered lithium hydroxide supplier. Albemarle produces battery-grade lithium hydroxide monohydrate (LiOH·H2O) at three primary locations: (1) La Negra complex, Antofagasta, Chile — converting Atacama brine-derived lithium chloride to LiOH; (2) Kemerton Lithium Hydroxide Plant, Western Australia — a JV with Mineral Resources Ltd (MRL) that converts spodumene from Greenbushes Mine to LiOH; Train 1 (50,000 t/year) commissioned 2022, Train 2 (50,000 t/year) commissioned 2023. (3) Kings Mountain, North Carolina — historically the world's largest lithium mine (operated 1953-1988), being restarted with US DOE/DOD support for domestic LiOH production. Albemarle is the preferred LiOH supplier for Tesla (NCA cathodes), BMW i-series, and multiple US and Asian battery makers requiring high-nickel chemistry. The 2023-2024 LiOH price collapse compressed Albemarle margins substantially; ALB stock fell ~75% from its 2022 peak.

Ganfeng Lithium Co., Ltd. (SHEX: 002460, HKEX: 1772; HQ Xinyu, Jiangxi, China; ~$5B revenue) is China's largest and the world's third-largest lithium producer, with dominant capacity in lithium hydroxide conversion. Ganfeng operates multiple LiOH conversion facilities in Xinyu (Jiangxi), Xinjiang, and Chongqing — collectively processing imported spodumene from Mount Marion (WA; 50% JV with Mineral Resources) and brine concentrate into battery-grade LiOH·H2O. Ganfeng supplies LiOH to BMW, Tesla, LG Energy Solution, CATL, and BYD for NMC-811 and NCA cathode manufacturing. Ganfeng's vertical integration — from Australian spodumene mining through Chinese conversion to battery material supply — exemplifies China's control of the LiOH processing chain. Ganfeng also produces lithium metal (for solid-state battery anodes) and other specialty lithium chemicals. Source: Ganfeng Lithium Annual Report 2023.

SQM (Sociedad Quimica y Minera de Chile; NYSE/Santiago: SQM; ~$10.5B market cap 2025; HQ Santiago, Chile) produces battery-grade lithium hydroxide monohydrate alongside lithium carbonate from the Salar de Atacama. SQM's Antofagasta chemical plant converts brine-derived lithium chloride concentrate to both Li2CO3 and LiOH·H2O for export. SQM is the world's largest single producer of lithium chemicals by volume. SQM's LiOH is produced via a causticization route (Li2CO3 + Ca(OH)2 → 2LiOH + CaCO3) rather than the direct spodumene route used by hard-rock converters. Battery-grade LiOH requires >56.5% LiOH content, low impurities (Na <0.005%, Fe <0.001%). In May 2024, SQM signed a public-private partnership with Codelco giving the Chilean state 50%+1 from 2025 to 2060. SQM produced 201,000 MT LCE total in 2024; LiOH accounted for a growing share as NMC-811 adoption accelerated. Source: SQM Annual Report 2023.

Tianqi Lithium Corporation (SHEX: 002466, HKEX: 9696; HQ Chengdu, Sichuan, China; ~$4B revenue) is one of China's two largest lithium producers and the builder of the first major lithium hydroxide refinery outside China. Tianqi owns 51% of Talison Lithium (Greenbushes Mine, WA; the world's largest hard-rock lithium mine) alongside Albemarle (49%). Tianqi's Kwinana Lithium Hydroxide Plant (Western Australia; 48,000 t/year design capacity) was the first large-scale LiOH conversion facility built outside China, completed ~2021 — but faced severe operational challenges including quality issues, staffing shortfalls, and equipment problems that kept utilization rates low for multiple years. Tianqi also operates LiOH conversion facilities in Sichuan and Jiangsu, China. Tianqi additionally holds 22.16% of SQM. The combination of Greenbushes mine control and Kwinana LiOH processing was intended to create a non-Chinese LiOH supply chain, but persistent Kwinana underperformance undermined this goal.

Mineral Resources Limited (ASX: MIN; HQ Perth, WA; ~$4B revenue) is an Australian mining services and lithium company that is a 40% JV partner with Albemarle in the Kemerton Lithium Hydroxide Plant in Western Australia. MinRes also operates the Mount Marion spodumene mine (50% JV with Ganfeng Lithium), contributing feedstock to the Chinese LiOH supply chain. Kemerton is a two-train LiOH plant (Train 1 and Train 2, each 50,000 t/year; 100,000 t/year total capacity) that converts spodumene from the nearby Greenbushes mine. MinRes experienced financial stress in 2024-2025 from debt load accumulated during lithium expansion; the company's founder Chris Ellison faced governance controversy. Despite these challenges, Kemerton remains one of Australia's largest industrial investments and one of the few large-scale LiOH plants outside China.

Arcadium Lithium was created January 4, 2024 from the all-stock merger of Allkem (Australian hard-rock/brine miner) and Livent (US lithium hydroxide/carbonate processor, formerly FMC Lithium). Livent's Bessemer City, NC plant was one of the only US-based lithium hydroxide processing facilities, producing LiOH from Argentine brine-derived feedstock. Rio Tinto acquired Arcadium in an all-cash $6.7B deal completed March 2025, making Rio Tinto the world's third-largest lithium producer. The acquisition gave Rio Tinto access to Livent's LiOH processing technology and North American LiOH capacity — now one of the only non-Chinese LiOH production points in North America. Arcadium/Livent had historically supplied BMW and other European automakers requiring battery-grade LiOH for NMC cathodes. Source: Rio Tinto acquisition announcement October 2024; Reuters.

POSCO Holdings (KRX: 005490, NYSE: PKX; HQ Pohang, South Korea; ~$60B revenue) is a global steel conglomerate that has built one of the few non-Chinese large-scale lithium hydroxide conversion chains. POSCO's lithium hydroxide strategy centers on POSCO Pilbara Lithium Solution (PPLS) — an 82:18 JV with Pilbara Minerals that completed South Korea's first dedicated LiOH plant at Gwangyang (Yulchon Industrial Complex, South Jeolla Province) in 2024, with 43,000 tonnes/year capacity. The plant imports spodumene from Pilbara Minerals' Pilgangoora Mine (WA) and converts via sulfuric acid pressure leach. South Korea's KORUS FTA status means POSCO-processed LiOH qualifies as FTA-country material under IRA FEOC rules — making it commercially valuable for US EV supply chains. POSCO's LiOH is targeted at LG Energy Solution, Samsung SDI, and SK On. Source: POSCO newsroom 2024; Pilbara Minerals ASX releases.
