PhD in Mathematical Models For Improved Lithium Ion Batteries

The tuition fee is 24,433 USD per year; applications for the Sep 2026 intake close on Aug 31, 2026.

Lithium-ion batteries are key to the low-carbon economy, with a market value expected to reach $216.5Bn by 2028. This PhD project, based in the School of Mathematics and Physics, focuses on developing mathematical models to improve their peak current capabilities and cell lifetime.

Through this programme, you will develop versatile mathematical modelling skills, become an expert in a burgeoning technology, and join a thriving research community, including the Faraday Institute and industrial collaborators.

To tackle the intellectual challenge of optimizing battery performance, the project involves using partial differential equations and a combination of analytical and numerical methods. The successful applicant will work closely with experimentalists and industrialists to refine the models and inform design changes. The Faraday Institution community provides additional support and collaboration.
