PhD Studentship Separating Ion and Electron Transport Kinetics in Aqueous Ion Storage Battery Materials

University of Southampton has an opening PhD position. The funds for this fellowship are available for 5 years. The deadline for applying is March 05, 2019.

PhD Description: During this project you will develop an understanding of the relative rates of electron and ion transport in aqueous metal-ion storage batteries; determining the factors that influence battery capacity, charging and discharge rates, and cycle life. Such electrodes represent a viable solution to grid-scale storage.

We will use operando energy dispersive EXAFS (EDE) to follow the changes in the oxidation state of the metal ions that make up the electrode material during charging and discharge in real time. The Prussian blue analogue (PBA) materials have been selected as exemplars of cathode materials for Na and Zn ion storage. They have good capacities, but increased mechanistic understanding is needed to fully understand their operation and direct a more rational approach to the design of the next generation of materials.

You will prepare the PBA materials, fully characterise them using a variety of methods including XRD and SEM, prepare these as battery electrodes and characterise their electrochemical performance as sodium and zinc ion storage electrodes. This will provide you with a range of skills transferrable to the study of other battery chemistries.

Starting with operando cell designs previously developed in our group you will adapt these so that the EDE data will be characteristic of the conditions of the optimised battery cell. You will then collect and analyse the EDE data and implement combined EDE and XRD on the I20 beamline. This will provide you with a range of skills transferrable to the study of other materials and catalysts.

You will be based at the University of Southampton in the laboratory of Prof. Andrea Russell. You will be seconded to the Diamond Light Source for approximately half of your time to work with Dr. Monica Amboage, to complete your EDE measurements and participate in developments on the I20 beamline.

The project is funded for 3.5 years and welcomes applicants from the UK and EU who have or expect to obtain at least an upper second class degree in Chemistry or allied subjects/relevant disciplines. Funding will cover fees and a stipend at current research council rates per annum. (201819 rates were 14,777 and should increase for 201920)

Due to funding restrictions this position is only open to UK students and EU students who meet the RCUK eligibility criteria
