Structural Energy Storage in Clay-Based Soils

About the Project

Structural energy storage is an emerging field with the potential to transform sustainable infrastructure in which materials are designed to simultaneously perform mechanical and energy storage functions. While early research has focused on composites and cementitious systems, this PhD project will investigate a largely unexplored alternative: natural clay soils enhanced with conductive and electrochemically active phases. Clay minerals possess charged nanoscale surfaces, rich pore-fluid chemistry, and unique physico-chemical interactions. These characteristics make them a promising yet under-studied platform for electrochemical energy storage. The aim of this PhD is to establish a fundamental, experimentally grounded understanding of how electrochemical functionality can be introduced into clay-rich geomaterials without compromising their mechanical performance in geotechnical applications.

Student activities

The PhD will combine laboratory experimentation, materials characterisation, and data analysis. The work will involve investigating the electrochemical behaviour of natural and engineered clays, performing electrochemical measurements alongside geotechnical and physical characterisation of the materials, and examining the interactions between mechanical behaviour and electrochemical processes. The project will focus on developing mechanistic understanding that can inform future large-scale or in-situ applications of clay-based energy storage.

Student benefits

The studentship will provide (i) interdisciplinary training across engineering, chemistry, and materials science, (ii) hands-on experience with advanced geotechnical, electrochemical and material characterisation techniques and (iii) opportunities to collaborate across departments and research groups at Imperial College London.
