Edmund Dickinson

Senior Research Scientist

Edmund leads the computational modelling and theory work of the Electrochemistry Group, focusing on predictive modelling of energy storage devices, electrochemical hydrogen technologies (fuel cells and electrolysers), corrosion phenomena and interfacial electrochemistry.

Biography

Edmund joined NPL in 2018, having spent six years supporting multiphysics modelling in British industry and academia at commercial simulation software company COMSOL. Previously, he studied chemistry at the University of Oxford and completed his doctoral research at Oxford in 2011, researching mass and charge transport phenomena in electrolyte solutions under the supervision of Prof Richard Compton.

Edmund has published 44 peer-reviewed papers (h-index: 22) in the field of numerical simulation in electrochemistry. With Richard Compton and Christopher Batchelor-McAuley, he is a co-author of the textbook Understanding Voltammetry: Problems and Solutions (Imperial College Press). He is a committee member of the Electrochemistry Interest Group of the Royal Society of Chemistry (RSC), and is a member of the Electrochemical Society (ECS).

Areas of interest

Through his work at NPL, Edmund aims to extend the scope and usefulness of electrochemical theory, including numerical simulation. His priority is the realisation of modelling results – and interactive models themselves – for use in industrial research and development by engineers and scientists who may be experts in their field but do not necessarily consider themselves “simulation experts”.

His current projects include:

  • development of multiphysics models of polymer electrolyte membrane fuel cells and electrolysers, including strict appraisal and review of existing literature work
  • analysis of electrochemical impedance spectroscopy (EIS) as a predictor of cell condition for lithium-ion batteries
  • establishment of theory underpinning in situ diagnostics for lithium-ion batteries and supercapacitors, considering novel electrochemical measurements and their combination combined with spectroscopic or thermometric techniques
  • creation of straightforward models of aqueous systems combining electrochemistry with complex acid-base chemistry – for example, the electrochemistry of steel cracks and crevices.

Edmund retains a strong interest in fundamental electrochemical theory: he believes that future developments of key practical relevance to electrochemical engineering depend on consolidation of theoretical approaches from traditionally separate disciplines, such as electroanalysis and chemical physics.
