Lithium hydroxide, primarily in the form of monohydrate (LiOH·H₂O), is a white crystalline powder that is highly hygroscopic. It is strongly alkaline and corrosive, requiring airtight storage to prevent moisture absorption. When exposed to air, it absorbs carbon dioxide and converts into lithium carbonate. It is readily soluble in water but only slightly soluble in ethanol. Due to its higher reactivity compared to lithium carbonate, it requires lower sintering temperatures, making it the preferred material for producing high-nickel ternary cathode materials. The industry chain encompasses upstream lithium resource mining and beneficiation, midstream lithium salt refining, and downstream cathode, battery, and end-use applications. China has a complete domestic closed-loop system, while global resources are dispersed, with refining and manufacturing concentrated in China.

Where to start

Two primary lithium sources supply upstream resources: hard-rock spodumene ore (the current main raw material for lithium hydroxide) and brine from salt lakes (a lower-cost future pathway), with a smaller supplementary amount from lepidolite. Spodumene hard-rock lithium extraction accounts for 64% of global lithium resources, concentrated in Australia, Africa, North America, and China's Sichuan region. The mining and beneficiation process involves open-pit mining, crushing and grinding, flotation purification, and production of 6% grade spodumene concentrate, the industry standard feedstock. Key global production areas include Australia, with major projects like Greenbushes, Pilgangoora, Wodgina, Mt Marion, Kathleen Valley, and Mt Holland. In Africa, Zimbabwe hosts projects like Sinomine Resource Group's Bikita, Shengxin Lithium Energy's Sabi Star, Huayou Cobalt's Acaidia, and Yahua Group's Kamativi. Mali has Ganfeng Lithium's Goulamina and Hainan Mining's Bougouni, while the Democratic Republic of Congo features Zijin Mining's Manono. Domestically, spodumene resources are mainly in Sichuan and Xinjiang, with projects like Jiajika, Yelonggou, and Lijiagou in Sichuan, and Dahongliutan and the Ruoqiang County Washixia South lithium mine in Xinjiang. Representative companies include Albemarle, SQM, and Livent overseas, and Tianqi Lithium, Yahua Group, Shengxin Lithium Energy, and Rongjie Stock in China.

Salt lake brines offer cost advantages, primarily producing lithium carbonate, with lithium hydroxide as a new process expansion. Production is concentrated in the "Lithium Triangle" of Chile, Argentina, and Bolivia in South America, and domestically in Qinghai and Tibet. The extraction process involves pumping underground brine, solar evaporation, adsorption/membrane separation for DLE (Direct Lithium Extraction), and impurity removal to produce lithium solution. Key production areas in South America include Chile's Atacama, along with Argentina and Bolivia. In China, key salt lakes are Qarhan, Dongtai Jinaier, Xitai Jinaier, Yiliping, Dachaidan, and Balun Mahai in Qinghai, and Zabuye in Tibet. While unit costs are much lower than ore, separating magnesium and lithium impurities is difficult. Direct production of battery-grade lithium hydroxide from brine is still being scaled up; currently, most salt lake companies first produce lithium carbonate, which is then causticized to convert it into lithium hydroxide. Representative companies include SQM, Ganfeng Lithium, Zangge Mining, Tibet Mining, and Salt Lake Industry.

Lepidolite serves as a domestic supplementary raw material, mainly located in Jiangxi province. Characterized by the sulfuric acid roasting method for lithium extraction from Yichun lepidolite ore, it has many impurities and low lithium content, serving only as a supplementary source for lithium salt production. Representative companies include Yongxing Special Materials, Jiangte Motor, Guoxuan High-Tech, Zijin Mining, and Dazhong Mining. Supporting materials include sulfuric acid, soda ash, quicklime, extractants, filter media, and beneficiation reagents, along with spodumene concentrate shipping logistics and salt lake evaporation facilities.

Why just 10 ASX 200 shares?

The midstream refining and processing stage takes upstream lithium ore and brine as raw materials to produce battery-grade lithium hydroxide monohydrate, with automotive-grade purity of ≥99.5% and strict control of heavy metal impurities at the ppm level. This is the highest technology barrier segment in the industry chain. The two mainstream production processes are the spodumene sulfuric acid method, which is the industry mainstream accounting for 74% of domestic capacity, and the lithium carbonate causticization method, a flexible supplementary route accounting for 26% of domestic capacity. The spodumene sulfuric acid method involves roasting spodumene concentrate at 1100°C for crystal transformation, sulfuric acid acidification leaching, multi-stage impurity removal, causticization reaction, evaporative crystallization, drying and sieving to produce battery-grade lithium hydroxide. Its advantages are high product purity, stable batch quality, and suitability for high-nickel ternary materials; its disadvantages include high energy consumption, large solid waste volume, and reliance on Australian spodumene concentrate as raw material. The lithium carbonate causticization method uses industrial-grade lithium carbonate produced from salt lakes or lepidolite, plus quicklime, undergoes causticization displacement, and then purification and crystallization to produce lithium hydroxide. Its advantage is flexible switching of lithium carbonate raw materials, making it a common process for salt lake companies; its disadvantage is an extra processing step, resulting in higher overall costs than the direct ore method. Comparing the two processes, direct lithium hydroxide production from spodumene is the domestic mainstream process, offering high product purity suitable for battery-grade lithium hydroxide but highly dependent on spodumene concentrate. The lithium carbonate causticization method is the mainstream process for salt lake companies, with costs depending on lithium carbonate prices; it is widely used by SQM and Livent overseas. Direct electrolysis of lithium hydroxide from salt lakes skips the lithium carbonate intermediate step, using DLE brine directly to electrolyze lithium hydroxide, offering significant cost reduction potential, but it is currently in small-scale pilot trials with capacity gradually coming online.

Product classification includes battery-grade lithium hydroxide (the mainstream demand), specifically supplied for high-nickel ternary materials like NCM622, NCM811, and NCA, with strict impurity control, accounting for 90% of lithium hydroxide consumption. Industrial-grade lithium hydroxide is used in lubricating greases, aviation lubricants, and alkaline batteries, while high-purity/nuclear-grade lithium hydroxide serves the military and special materials sectors, a niche high-end market. Global nominal capacity stands at 1.185 million tons per year, with China's capacity at 976,000 tons, accounting for 82% of the global total, of which causticization capacity accounts for 26% and refining capacity for 74%. Overseas capacity is 209,000 tons, including operations like Kwinana in Australia and facilities in Chile and North America by Albemarle. In 2025, China's total lithium hydroxide production was 306,200 tons, a year-on-year decrease of 13.4%, compared to 2022-2024 outputs of 245,100 tons, 283,000 tons, and 353,600 tons, with year-on-year growth rates of 37.51%, 15.49%, and 24.92%, respectively. The 2025 annual production decline was primarily due to downstream demand for ternary batteries for vehicle installation growing only 3.7% year-on-year, and high domestic lithium hydroxide inventory levels accumulated in the first half of last year, leading to a destocking focus for the year. Industry-wide operating rates range from 45% to 50%, significantly below nominal capacity, displaying severe structural differentiation. Integrated companies with their own lithium mines operate at 70% to 90% capacity, while small and medium-sized smelters that purchase ore operate at 30% capacity or even undergo long-term maintenance due to high raw material costs, directly reducing output when facing losses. Flexible production lines can adjust production between lithium hydroxide and lithium carbonate; when the price spread between the two is inverted, companies reduce lithium hydroxide output and switch to producing lithium carbonate.

Historically, China is the world's largest lithium hydroxide producer and a major net exporter, with exports primarily flowing to Japan and South Korea. According to customs data, China's cumulative lithium hydroxide exports in 2025 were 53,900 tons, with cumulative imports of 18,400 tons, maintaining a net export pattern. In the first half of 2026, cumulative exports were 22,700 tons, and cumulative imports were 31,700 tons, shifting to a net import pattern. Monthly data shows that starting from the second half of 2025, domestic lithium hydroxide exports have continued to decline while imports have increased significantly, with monthly data frequently switching between net export and net import status, and the trade surplus shrinking substantially. Looking ahead, with the continuous deployment of overseas local refining capacity and geopolitical policy influences, the global trade flow of lithium hydroxide is expected to be restructured. According to SMM data, the current total social inventory of lithium hydroxide in China is approximately 34,000 tons of physical material, representing about 30 days of inventory coverage, which is in a neutral to low range. In terms of inventory structure, smelter inventories are limited, mostly consisting of long-term pre-orders, with companies actively maintaining low inventory levels. Trader circulating inventory is low, and downstream cathode material companies purchase on demand, unwilling to actively build up inventory. The competitive landscape is highly oligopolistic domestically, with a CR5 of approximately 72%, and China holds over 70% of global lithium hydroxide production capacity. The first tier consists of integrated leaders like Ganfeng Lithium, Tianqi Lithium, Yahua Group, and Shengxin Lithium Energy. The second tier includes Rongjie Stock, Jiangte Motor, Yongxing Special Materials, and Yongshan Lithium Industry. Overseas players are Albemarle, SQM, and Livent with their overseas refineries.

A broader perspective on the market

The downstream sector begins with the direct application of lithium hydroxide in high-nickel ternary cathode materials. The reaction involves lithium hydroxide plus a nickel-cobalt-manganese precursor, which is sintered at high temperature to produce NCM811, NCM9, or NCA. Why not use lithium carbonate? High-nickel materials require lower sintering temperatures, where lithium hydroxide's higher reactivity ensures more complete lithium embedding; lithium carbonate, at high temperatures, can cause nickel dissolution and cycling decay. Low-nickel ternary and lithium iron phosphate (LFP) only use lithium carbonate, not lithium hydroxide. Leading cathode material companies include Ronbay Technology, Easpring Material Technology, GEM Co., Ltd., XTC New Energy Materials, and Brunp Recycling (recycling). The next layer involves battery cell manufacturing, where cathode materials are combined with anodes, electrolytes, and separators to produce power batteries and energy storage batteries. Domestic battery manufacturers include CATL, BYD, Guoxuan High-Tech, CALB, EVE Energy, Sunwoda Electronic, SVOLT Energy, Farasis Energy, Hithium Energy Storage, and REPT Batto. Overseas players include LG Energy Solution, Panasonic, SK On, and Samsung SDI. The final end-use applications are predominantly in power batteries, which account for 75.4% of core demand. High-end electric vehicles, luxury models, and long-range EVs are equipped with high-nickel ternary materials, and electric vehicle demand in Europe and North America continues to drive lithium hydroxide imports. Economy cars primarily use LFP, which does not consume lithium hydroxide. Energy storage batteries, accounting for 18.3% of demand and the fastest-growing segment, use high-nickel ternary routes for long-duration storage, commercial and industrial storage, and grid frequency regulation, with demand growth accelerating year by year. Consumer electronics, at 3%, uses cylindrical ternary batteries in high-end laptops, drones, and wearable devices. Traditional industrial applications, at 3.3%, include high-temperature lubricating greases, aerospace lubricating oils, alkaline batteries, ceramics, and optical glass. The lithium battery recycling industry uses hydrometallurgical recovery from spent ternary batteries to regenerate lithium hydroxide, forming a closed-loop cycle, with companies like GEM Co., Ltd., Brunp, and Huayou Cobalt having established operations.

The industry chain's transmission logic and pricing are driven by cost, where the price of raw materials like spodumene concentrate and brine directly determines the cost of lithium hydroxide. Integrated companies with their own mines have strong anti-cyclical profitability, while companies that purchase ore experience highly volatile profit margins. The route differentiation is clear: lithium carbonate corresponds to LFP and low-nickel ternary materials, while lithium hydroxide is tied to high-nickel ternary materials, making industry demand entirely dependent on the penetration rate of high-nickel batteries. Geographic division of labor sees upstream resources concentrated in Australia, South America, Africa, and domestic regions like Sichuan, Qinghai, Tibet, and Jiangxi. Midstream refining is heavily concentrated in China due to its complete chemical industry support and low-cost manufacturing. Downstream demand is concentrated in the four major markets of China, South Korea, Japan, and Europe. The cycle linkage means that lithium ore, lithium hydroxide, ternary cathode materials, and new energy vehicle prices move in the same direction, making the industry highly cyclical. The pricing system uses SMM's battery-grade lithium hydroxide (coarse particle) mainstream spot quotation as the market benchmark. This is divided into long-term contract prices, which are locked in by major cathode manufacturers on a monthly or quarterly basis, and spot market prices. Long-term contracts generally trade at a slight discount to spot prices. The price linkage relationship shows that lithium hydroxide prices follow lithium carbonate fluctuations. Under normal conditions, lithium hydroxide trades at a premium of 6,000 to 12,000 yuan per ton over lithium carbonate. If this premium narrows to below 4,000 yuan per ton, companies using the causticization route stop switching production to lithium hydroxide, leading to supply contraction. Since lithium carbonate was listed for trading in China in July 2023, it has been priced at a premium to lithium hydroxide almost all the time, with the current premium of lithium carbonate over lithium hydroxide exceeding 11,000 yuan per ton.
