All solid-state zinc-air flexible battery by additive manufacturing (HUIOU20SF)


Project Description

Applications are invited to School of Engineering, UEA, 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 devices such as metal-air battery [1]. The secondary solid-state flexible zinc-air battery has demonstrated high energy density and better operational safety compared with some rechargeable batteries [2]. However, practical applications of zinc-air battery 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 [3].

Considering that wearable electronics have become increasingly pervasive in daily life, the demand for flexible energy storage devices is increasing [4, 5]. This PhD project aims to develop a novel direct-ink-writing technology to fabricate a solid-state flexible zinc-air battery. The PhD candidate will prepare some nano-sized electrode materials with controllable physical, electrical and chemical properties, determine how the properties of the electrode materials enhance the activity towards ORR and OER and evaluate the performances of the solid-state zinc-air battery in terms of specific capacity, rate performance, energy and power densities, and cycle life.

The project may be available at an earlier start point of July 2020 if an applications is submitted at the appropriate time and should be discussed with the primary supervisor in the first instance.

This is a PhD programme.

The start date of this project is October 2020.

The mode of study is full-time.

Entry requirements: Acceptable first degree in Chemistry, Engineering (or other related STEM subjects), the standard minimum entry requirement is 2:1.

Funding Notes

This PhD project is offered on a self-funding basis. It is open to applicants with funding or those applying to funding sources. Details of tuition fees can be found at View Website.

A bench fee is also payable on top of the tuition fee to cover specialist equipment or laboratory costs required for the research. Applicants should contact the primary supervisor for further information about the fee associated with the project.
