Applications are invited to School of Engineering for a PhD in the field of additive manufacturing and electrochemistry for energy storage.
High-performance electronics and electric vehicles have accelerated the development of advanced energy storage device such as metal-air batteries [1-3]. Secondary solid-state zinc-air batteries (ZABs) have demonstrated high energy density and better operational safety compared with some rechargeable batteries . However, practical applications of ZABs are still seriously hindered due to the relatively poor performance of the air electrodes, such as sluggish reaction kinetics towards oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) and high overpotentials in both ORR and OER and hence low energy efficiency.
Considering that wearable electronics have become increasingly pervasive in daily life, the demand for solid-state energy storage devices is increasing . This project aims to develop a novel additive manufacturing technology to print solid-state ZABs. The PhD candidate will prepare some nano-sized electrode materials with controllable physical, electrical and chemical properties. The candidate will determine how the properties of the electrode materials enhance the activity towards ORR and OER. Finally, the candidate will evaluate the performance of the solid-state ZABs in terms of specific capacity, rate performance, energy and power densities, and cycle life.
