PhD Studentship: Next-generation electrolytes for aluminium-based batteries

at  University College London

STUDENTSHIP DESCRIPTION

Next-generation anode research is a rapidly developing field that seeks to replace Li-based anodes with alternative technologies (Na, K, Mg, Ca, Al) that offer higher capacity, improved safety or greater sustainability metrics. Amongst these, aluminium anodes offer unparalleled volumetric energy densities combined with extremely low cost, high earth abundance and well-established refining methods. However, the fundamental electrochemistry is limited by the difficulty of achieving a reversible 3-electron redox reaction with conventional electrolyte systems. Commercial electrolytes cannot coordinatively stabilise the Al3+ cation which results in large overpotentials and low coulombic efficiencies for its plating and stripping, these characteristics are untranslatable to devices. This project aims to develop novel electrolyte systems by combining computational discovery with robust syntheses, and assess their compatibility with the Al anode through electrochemical testing and materials characterization. This multidisciplinary approach aims to rapidly accelerate the commercial viability of the technology, delivering high scientific impact whilst providing a well-rounded skillset to the prospective student.
