With the global energy transition and the advancement of sustainable development strategies, the new energy industry has become a key driver of economic growth and technological innovation. Among the many sectors within this industry, lithium battery technology has attracted significant attention due to its high efficiency and environmentally friendly characteristics, and it is widely used in electric vehicles, portable electronic devices, and large-scale energy storage systems. As the core raw material of lithium batteries, lithium's importance is increasingly recognized, earning it the title of "white petroleum of the 21st century."
However, with the rapid surge in lithium demand, traditional lithium mining methods are struggling to meet market needs and are facing dual challenges of environmental pressure and resource depletion. In this context, salt-lake lithium extraction technology has emerged as a major direction for lithium resource development due to its high resource utilization, low environmental impact, and cost-effectiveness. This technology leverages innovative chemical treatment and separation methods to efficiently extract high-purity lithium from lithium-rich salt-lake brine, enhancing resource utilization while providing a solid raw material foundation for the sustainable development of the new energy industry, contributing to the construction of a clean, low-carbon, and efficient energy system.
HAIPU Lithium Adsorbents
HAIPU offers lithium adsorbents across three categories: aluminum-based, titanium-based, and manganese-based. It is among the first suppliers domestically and internationally to industrially implement both aluminum- and titanium-based adsorbents.
Given the heterogeneous nature of salt-lake resources, HAIPU has upgraded its aluminum- and titanium-based products to the fourth and second generations, respectively, significantly enhancing adsorption capacity, adsorption rate, and low-temperature resistance. These products are suitable for diverse scenarios, including high-magnesium old brine, sulfate-magnesium subtype original brine, oilfield brine, direct lithium extraction from carbonate-type brine, and selective separation of lithium and sodium from mother liquors.
Aluminum-Based Adsorbents
Fourth-Generation HP160 Series: Particle size 0.5–2 mm, adsorption capacity ≥5.5 g/L, annual loss ≤5%. Suitable for pH 4–8, applicable for direct lithium extraction from old or original brine. Exhibits excellent sulfate resistance, fast adsorption rate, low impurity ions in the product solution, low water consumption, and hydraulic resistance, enabling operation without inert filler beads and improving equipment space utilization.
Fourth-Generation HP170 Micro Aluminum Series*: Particle size 0.2–0.4 mm, adsorption capacity 7 g/L, annual loss ≤5%. Suitable for pH 4–8, excellent sulfate resistance, ideal for scenarios requiring low water consumption.
Titanium-Based Adsorbents
Second-Generation HP180 Series: Particle size 0.5–2 mm, adsorption capacity ≥6 g/L, annual loss ≤10%. Suitable for pH 7–14, strong acid-alkali resistance, low dissolution loss, fast adsorption rate. Applicable for direct lithium extraction from carbonate brine and mother liquors. HAIPU's titanium-based lithium adsorbents represent the first industrial-scale application for lithium extraction from alkaline salt lakes worldwide.
HAIPU possesses the most comprehensive range of lithium adsorbent products in the industry, with strong R&D and product iteration capabilities. It can rapidly adjust and update its product line to achieve precise alignment with customer needs, supporting highly efficient industrial-scale production. Through continuous cycles of R&D, pilot testing, large-scale production, and product optimization, HAIPU consistently delivers high-quality, stable industrial products.
Technological Innovation Expands Application Scenarios
Most existing lithium adsorbents are only suitable for salt lakes in Qinghai, China, or in Argentina, South America. HAIPU's newly developed titanium-based adsorbents expand the application scope of lithium extraction technology, effectively reducing dissolution losses during lithium recovery to meet industrial application standards. This solves the low recovery issue of dry-granulated lithium materials and allows use in oilfield subsurface brine, carbonate-type salt lakes in Tibet, and overseas low-magnesium sulfate-type salt lakes.
Additionally, HAIPU's impurity-removal adsorption technology improves the quality and yield of the final lithium product. Combined with efficient extraction technology for rare elements like rubidium and cesium, it drives innovation across the full process of salt-lake resource extraction.
HAIPU's newly developed small-particle aluminum-based adsorbents are suitable for shallow-bed processes, optimizing bed filling and processing capacity to significantly increase adsorption exchange rates. Using HAIPU's patented shallow-bed adsorption equipment and adsorbents, high flow rates can be achieved, saving both adsorbents and water, which is especially beneficial in water-scarce regions such as Xinjiang and overseas salt-lake lithium projects.
Lithium Adsorbent Application Cases
HAIPU Salt-Lake Lithium Extraction Solution
HAIPU's salt-lake lithium extraction solution centers on proprietary lithium extraction materials. Lithium is selectively extracted from brine, followed by elution, enrichment, and impurity removal to effectively separate lithium from magnesium, sodium, boron, and other elements. HAIPU provides all core products, including lithium adsorbents, ion-exchange membranes, and impurity-removal resins, as well as supporting equipment design, manufacturing, installation, commissioning, and operation services. The process requires no chemical additives, ensuring environmental friendliness. After lithium extraction, other brine components remain unchanged and can be directly reinjected into the salt lake.
Compared with traditional salt-lake lithium extraction methods such as membrane, calcination, extraction, and evaporation-precipitation techniques, HAIPU's solution significantly improves lithium extraction efficiency while reducing energy consumption, achieving major breakthroughs in cost, lithium recovery rate, and production cycle. This innovative technology is suitable for direct extraction from complex raw brines in salt-lake regions.
