Researchers at INM – Leibniz Institute for New Materials in Saarbrücken, Germany, in collaboration with scientists from the Chinese Academy of Sciences in Shanghai, have developed a new electrochemical process for extracting lithium ions from seawater. In ACS Energy Letters, the German-Chinese team led by Prof. Volker Presser presents the process, which on the one hand requires little energy input and on the other hand ensures continuous separation of lithium.
