1. Overall Mission

The overall aim of this PhD training is to develop understanding between the thermodynamic, fluid phase equilibria and electrochemical properties of a wide range of novel electrolytes for their uses in battery and supercapacitor applications. Specific objectives: (i) to measure simultaneously fluid phase equilibria through PVTxy measurements and electrochemical behaviours of a wide range of electrolytes; (ii) to investigate in situ the degradation of the electrolytes over the time by applying external stimulus (temperature, current, presence of gas, etc.); (iii) to determine the key parameters which improve the safety of formulated electrolytes (with or without the presence of an ionic liquid used herein as an additive); (iv) to develop an understanding of the relationship between the formulation of the electrolytes and their properties (volumetric, transport, thermal, phase equilibria and electrochemical behaviours, safety, etc.) by using different experimental and theoretical approached to link electrolytes macroscopic and microscopic properties.

2. PhD Programme and Methodology

The main challenge of this project is to: (i) provide information of the decomposition gaseous products during cycling of metal ion batteries and supercapacitors and how these are affected by electrolyte composition; (ii) design and formulate safer electrolytes; (iii) to collect data, under real conditions, essential to develop and test novel modelling tools. The overall programme is divided into four working packages (WPs) outlined below.

3. Eligibility

Qualifications: A Master in chemistry or related subject is necessary.

The highly-motivated student will have the opportunity to apply a variety of physical techniques (phase equilibrium; volumetric and transport properties; IR, Raman and NMR spectroscopies; DSC-TGA; various electrochemical properties, etc.) along with original thermodynamic models to design novel and safer electrolytes for energy storage applications.
