PhD Studentship: Laser Surface Engineering of Solid-state Batteries for Functionalisation of Electrochemical Performance

Applications are invited to undertake a 3.5 year PhD programme to explore new laser surface engineering methods for functionalising the electrochemical performance of solid-state batteries. 

In recent times, the most significant advancements have predominantly occurred in the realm of lithium-metal-oxide cathodes, while lithium anodes in SSBs have remained largely unchanged. Silicon, with its ability to provide a high charge capacity as the active material (AM) in anodes of all-solid-state batteries (ASSBs), has long been considered a promising medium for anodes. However, it may expand by up to 300% during charging, causing fluctuations, leading to internal mechanical stresses within the composite electrode, resulting in issues such as loss of electrical contact and delamination, thereby impeding its seamless integration into industrial battery production.

While numerous researchers are exploring various promising approaches to facilitate the incorporation of silicon alloys in electrodes, the potential implementation of additional porosity and functionalisation of surface textures through laser patterning remains an under-researched area. 

There is growing evidence in literature that, for example nanowire geometry in silicon anodes allows less swelling compared to spherical nanoparticles, therefore there is a need not only to functionalise the geometry of the silicon nanowire anode technology but also to produce a basic understanding of the geometrical/topographical effect of the nanofeatures on the battery performance. 

This exciting PhD project will benefit from direct involvement of academics working in the laser manufacturing and the battery technology fields. Upon completion of the PhD, the candidate will develop a wide range of technical and transferable skills ideal for pursuing their career both in academia and in industry.

Funding information:

The Wolfson School of Mechanical, Electrical and Manufacturing Engineering is offering a PhD studentship to fund one of three advertised projects commencing July 2025. Projects starting with the advert reference ‘SA24’ will be competitively assessed.

The funding award is for 3.5 years and provides a tax-free stipend of £19,237 per annum plus tuition fees at the UK rate. The studentship also offers a £2,000 Research Training Support Grant.  Due to funding restrictions, this Studentship is only available to those eligible for UK fees.

Entry requirements:

Applicants should have, or expect to achieve, at least a 2:1 Honours degree (or equivalent) in Manufacturing/Mechanical/Materials/Chemical Engineering or a related subject. A relevant Master’s degree and/or experience in one or more of the following will be an advantage: Advanced Processes and Technologies, Chemistry, Battery Technology/Materials.

English language requirements:

Applicants must meet the minimum English language requirements.

How to Apply: 

Apply online via the above ‘Apply’ button. Under programme name, select ‘Mechanical and Manufacturing Engineering’ and quote the advert reference number ‘SA24-WS-MP’ under the ‘Finance’ section of the application.

Applications must include a personal statement, up-to-date curriculum vitae (CV), details of two referees (one from your highest degree qualification), and certified academic certificates and transcripts for all completed degree programmes. Submission of a Research proposal is not essential but may strengthen your application.

Incomplete applications received after the advert closing date may not be considered for interview. Interviews are expected to be held in late April/May 2025. You will be contacted by the project supervisor if shortlisted for interview.

The School will use the selection criteria to help make a decision against your application.
