A recent advancement in lithium extraction has garnered significant attention within the scientific community. The researchers at the Korea Institute of Fusion Energy (KFE) have uncovered a more effective method for extracting lithium through the use of plasma technology. This pioneering approach has the potential to revolutionize the process of obtaining lithium, a vital component in various industries, particularly in the development of fusion energy.
Traditionally, the extraction of lithium involves combining sodium carbonate with lithium-containing saltwater to produce lithium carbonate. However, this method has its limitations, as it necessitates additional steps to separate lithium carbonate from sodium impurities. Consequently, researchers have been exploring alternative methods to streamline the extraction process.
One such alternative involves utilising carbon dioxide gas in place of sodium carbonate. While promising, this method has been found to have low extraction rates in lithium-rich brine. This is where the KFE’s research comes into play. Dr. Ji Hun Kim and Dr. Jong keun Yang have developed an innovative technique using carbon dioxide microwave plasma technology to substantially enhance the rate of lithium extraction.
The outcomes of their experiments are truly exceptional. Through a comparison of plasma technology with traditional extraction methods utilising simulated brine, the researchers discovered that plasma technology increased extraction rates by approximately threefold. In fact, while direct injections of carbon dioxide gas yielded a 10.3% extraction rate, the use of carbon dioxide plasma led to an extraction rate of 27.87%.
This research is especially significant as it is the first of its kind to demonstrate such a remarkable increase in lithium extraction rates through the use of plasma technology. The findings were published in DESALINATION, a highly esteemed academic journal within the field of water resources, further enhancing the research’s credibility.
Dr. Yang, the lead author of the research paper, underscored the impact of carbon dioxide plasma on lithium extraction rates. He emphasised the potential of heat and ions, electrons, and radicals generated by carbon dioxide plasma to enhance the extraction process. The team’s plans to expand their research into plasma lithium extraction processes represent a significant step forward in advancing this technology.
The implications of this research extend beyond the laboratory. President Suk Jae Yoo of KFE highlighted that this breakthrough opens up new possibilities for plasma technology, which has traditionally been associated with cutting-edge fields such as semiconductors. Additionally, he underscored the importance of lithium obtained from seawater in fusion energy generation and reiterated the institute’s commitment to further research in fusion energy development and fuel acquisition.
The Korea Institute of Fusion Energy (KFE) is a leader in nuclear fusion research, particularly with the development and operation of KSTAR, a superconducting fusion research device. The institute’s dedication to achieving groundbreaking research results, developing core fusion technology, and training exceptional personnel underscores its commitment to advancing the field of nuclear fusion.
As the KFE continues to spearhead efforts in ushering in the era of nuclear fusion energy, their innovative research into plasma-based technologies holds tremendous promise. By developing plasma technologies applicable in various industries, including high-tech, environment, and agriculture, the institute is striving to make a meaningful and lasting impact on society.
With the potential to transform lithium extraction and contribute to the advancement of fusion energy, the KFE’s research serves as a testament to the power of innovation and scientific discovery. As we look towards a greener and more sustainable future, the role of groundbreaking research in shaping our world cannot be overlooked.
