Postdoc Researcher – Electrochemical purification of lithium from industrial
Lithium is a critical raw material essential to battery technologies powering the global energy transition. However, during the refining process for battery-grade lithium carbonate or lithium hydroxide, an estimated 40–70% of the lithium extracted from ore is lost in wastewater streams. Addressing this inefficiency is vital to building a more sustainable and circular lithium economy.
We are seeking a motivated and skilled Postdoctoral Researcher to join a collaborative project between Dr. Xiaohua Li at the University of Groningen and our industrial partner IonIQs. The focus of this project is the development of advanced electrochemical purification methods to recover lithium from industrial wastewater.
In this project, the postdoctoral researcher will focus on the fundamental understanding and process optimization of an electrochemical cell system incorporating redox-flow electrodes and ion-selective membranes for Lithium purification. The goal is to selectively remove impurities—such as sodium (Na), calcium (Ca), and magnesium (Mg)—from lithium-rich wastewater streams, thereby enabling the recovery of high-purity, battery-grade lithium.
The project will be supervised by academic PIs at the University of Groningen and the industrial partner, ensuring strong mentorship and research guidance. The research will be conducted mainly at the IonIQs laboratory on the Zernike Campus of the University of Groningen, offering a unique opportunity to work at the interface of academic research and industrial innovation.
This project offers an excellent opportunity to contribute to a sustainable and circular lithium economy by integrating materials science, electrochemistry, and membrane technology.
