Research Fellow in Mathematical Modelling Sodium-ion batteries

Research Fellow in Mathematical Modelling for Sodium-ion batteries

Location:

Portsmouth

Salary: £41,064 per annum

Contract type:
Fixed Term – Full‑Time, 37 contractual hours per week. Reference: REC. Duration: until 31 March 2030.

Applications are invited for the position of Research Fellow in the Applied Mathematics Group at the University of Portsmouth, School of Mathematics and Physics. The Fellow will work on the Multi‑scale Modelling Project funded by the Faraday Institution and will collaborate with a consortium that includes Imperial College London, University College London, Oxford, Southampton, Warwick, Birmingham, Bath, and Lancaster. The work will involve close collaboration with external collaborators and industrial partners.

The role focuses on developing advanced physics‑based continuum models for sodium‑ion batteries, particularly hard carbon anodes and phase‑changing layered oxide cathodes. The successful candidate will create a computational framework that bridges atomistic insights and cell‑scale behaviour, enabling improved understanding of multi‑mechanism sodium storage, phase transitions, and dynamic electrochemical response. The position offers an opportunity to contribute to next‑generation modelling tools that will accelerate design and optimisation of sodium‑ion battery technologies.

Applicants should hold a PhD (or equivalent research experience) in a highly numerate science subject. The main role is to develop a computational framework to test and validate models of sodium‑ion battery behaviour. Proficiency in computer programming (particularly Python) and knowledge of numerical methods for solving systems of partial differential equations are required. Familiarity with the electrochemistry of, and existing models for, sodium‑ion batteries is desirable.

A strong motivation for independent research and the ability to work with partners from other scientific areas is essential. Travel to work with partners is expected.

• Competitive salary, including incremental progression within your scale.
• Generous pension scheme.
• Generous leave entitlement of 32–35 days a year, plus bank holidays, and an additional Christmas closure.
• Family‑friendly policies supporting flexible working.
• Staff discounts and loyalty schemes.
• Staff car parking and discounted public travel.
• Excellent training and development opportunities.
• Staff wellbeing programmes.
• Recreation facilities, including discounted gym membership, food on campus schemes, use of the Library and staff social activities.
• Discounted learning.
• Start‑up business mentoring from expert entrepreneurs via our Entrepreneurs in Residence programme.
