safe operating windows, while the computational models intended to predict plating–stripping dynamics remain under-constrained by a lack of experimental evidence. This project addresses that gap directly.
Project overview
The successful candidate will develop a quantitative, non-destructive, in-situ diagnostic methodology for metallic lithium plating in industry-relevant cell formats. The approach is fundamentally based on diffraction and small-angle scattering techniques using both X-rays and neutrons, enabling the direct deconvolution of favourable bulk lithium-ion intercalation from unfavourable lithium plating. This multimodal combination probes the structural and spatial length scales relevant to the problem, with the sensitivity required to distinguish between the different forms of lithium present within a cell.
Beginning with single-layer pouch cells and then extending to larger cell formats, the student will systematically evaluate stimuli known to trigger plating, including cycling rate, negative-to-positive (N:P) electrode capacity ratio, and low-temperature operation, generating quantitative data to underpin both safer operating protocols and more accurate predictive models.
Significance
Lithium plating sits at the intersection of battery safety, performance, and the broader drive towards faster charging and extended cell lifetimes. Establishing a robust, non-destructive detection methodology will have direct implications for cell design, the definition of safe operating windows, and the next generation of physics-based degradation models grounded in measured rather than assumed parameters. This project offers a rare combination of fundamental scientific depth and clear industrial relevance.
Benefits to the candidate
Beyond the scientific outcomes, the student will gain hands-on experience working at the Battery Scale-up Facility at WMG, one of the UK's leading centres for battery research and manufacturing, alongside access to major international X-ray and neutron facilities like the Diamond Light Source and ISIS Neutron and Muon Source. This combination of industrial-scale and large-facility experience provides a distinctive and highly transferable skill set, well suited to a future career in academic research, industrial R&D, or the wider battery and energy storage sector.
Essential and Desirable Criteria
Eligible applicants must have or be expected to gain a minimum of a 2:1 class undergraduate degree in a relevant Science subject (e.g. Chemistry, Material science, Engineering, or Physics).
Prior experience with electrochemical, diffraction/scattering techniques is advantageous but not essential; what matters most is a genuine interest in quantitative experimental science and a willingness to engage with both large-scale facility work and applied battery research.
