The world urgently needs better battery technology to rapidly move towards a low‐carbon society. However, commercially‐available batteries currently do not store enough energy, have limited working lifetimes, and are too expensive to make large‐scale electrification viable. To design improved batteries, a better understand of chemical processes inside a battery during charging and discharging is needed. This requires measuring the flow of ions and electrons across multiple interfaces, buried within the battery. Abdulrhman’s PhD project will develop methodologies to study these interfaces using secondary ion mass spectrometry and X‐ray photoelectron spectroscopy. The project is co-supervised by Dr Alex Walton.
