Due to its critical role in producing batteries, most prominently for electric vehicles (EVs), lithium hydroxide is in high demand across the world. As a way of remaining competitive, lowering costs, and responding to growing demand for cleaner practices, top companies are embracing innovation in production processes as the need for lithium products keeps growing. Learn how some of the foremost companies in lithium hydroxide are innovating their production processes.
New Manufacturing Methods: Streamlining the Process
New and improved manufacturing methods are one of the key developments in lithium hydroxide production. Extraction of lithium from spodumene ore, then refining and converting it into lithium hydroxide, is the classic way of producing lithium hydroxide. The traditional process, however, could be expensive and energy-intensive. Leading companies are simplifying the process by utilizing more effective approaches, such as Livent and Albemarle. Some companies, for example, have created technology to extract lithium directly from brine or ore via chemical or electrochemical processes. Direct Lithium Extraction (DLE) enables lithium to be extracted directly from brine or ore by means of chemical or electrochemical processes. This technique is revolutionizing the industry by lowering the cost of total production, increasing yield, and requiring less energy. In addition, companies are leveraging alliances and acquisitions to enhance these technological advancements. For instance, Albemarle’s acquisition of Rockwood Holdings helped expand its lithium production capabilities, including innovations in DLE.
Greener Ways: Practices towards sustainability
Green processes become more and more important to lithium hydroxide firms as there is a greater need for production to be sustainable. In addition to developing new production methods, firms are also looking for ways to reduce the environment footprint of their production. One firm that uses sustainable methods, is SQM, an international lithium producer. The business has recently put into place a process called solar evaporation ponds to remove water from brine with a high percentage of lithium utilizing the natural heat of the sun and depositing lithium salts on its surface. The process is an environmentally friendlier alternative to lithium extraction since it uses less water compared to the conventional evaporation methods. Some companies are also exploring recycling as a central component in their sustainability plan. Li-Cycle, for example, has developed a recycling system for lithium-ion batteries that recovers precious lithium and other metals to go into new batteries. This reduces not only waste but also demand for virgin materials, helping build a more circular economy for the production of lithium.
