Modelling of battery slurry mixing using coupled continuum-discrete methods

Electrode slurry mixing is a critical step that irreversibly influences the subsequent steps in battery manufacturing. The process by nature is a complex phenomenon due to interplay between material constituents (containing both discrete phases and continuum medium) and process conditions (mixing speed and temperature). Understanding (and subsequently controlling) the role of individual factors and their combined effects will enhance the slurry uniformity that leads to consistent performance in battery electrodes. This project, therefore, will focus on simulating the slurry mixing process using combination of continuum and discrete approaches by coupled computational fluid dynamics (CFD) and discrete element methods (DEM).

<p style="margin-bottom:11px"><strong>Project Aims:</strong></p> <p>This project aims at simulating the slurry mixing process using combination of continuum and discrete approaches by coupled computational fluid dynamics (CFD) and discrete element methods (DEM) for detailed examination of the interactions between discrete phases (active material, conductive additives, and binder) and the surrounding continuous medium (solvent). The objectives are:</p> <ol> <li>Developing high-fidelity CFD-DEM simulations of mixing process;</li> <li>Simulating different impeller designs, speeds, and operational parameters to optimise energy efficiency and mixing time;</li> <li>Using the developed models for predicting how changes in mixer scale will impact slurry behaviour, helping to avoid scale-up issues in production.</li> </ol> <p><strong>Potential Impact</strong></p> <p>This project will provide a platform to conduct the fundamental research elements proposed and will enrich future research activities and be used as a springboard for future funding bids (e.g. EPSRC NIA for MJ and MB). Project also has a bigger societal impact by focusing on efficient electrified systems and reducing carbon emission.</p> <p>The set objectives and envisaged outcomes of this project will be potentially valuable to attract/engage with other local companies focused on ceramic processing (e.g. a current industrial partner working with MJ focused on fuel cell manufacturing).</p>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
