Comparing conventional and novel lithium extraction methods for a sustainable future

Abstract

Nowadays, lithium is used everywhere such as in electric cars, to store energy and also in gadgets that people use regularly. Because the need for lithium is increasing, there are lots of worries about the extraction methods and exacerbating outcomes for the environment. Some ancient methods for example hard rock mining and brine evaporation are used but that also come with some negative outcomes such as wastage of water, harmful environmental consequences and extreme energy consumption. To navigate this matter, researchers have invented new and novel techniques which include nanomaterial-based adsorption, membrane filtration, electrochemical separation and photocatalytic processes. Well, these advanced technologies not only offer a high efficiency but also improve the selectivity, and they also reduce the environmental impacts in comparison to traditional methods. However, factors such as high costs, scalability, may limit the use of these techniques on a large scale. This essay reviews the traditional as well as emerging lithium extraction technologies to analyze the benefits, issues and future directions. To conclude, to have a sustainable lithium extraction not only requires a combination of advanced technologies but also need productive and recycling methods to ensure a long-term lithium supply chain.
