Foivos is a Faraday Institution Research Fellow based across two departments in the Faculty of Engineering and Physical Sciences (FEPS), researching and developing cathode materials for lithium-sulfur batteries as part of project LiSTAr. He completed the MSc in 'Advanced Materials', here, at the University of Surrey and stayed on to conduct postgraduate research in FEPS, under a European Commission-funded PhD programme. His area of research was the fabrication, processing and testing of supercapacitors for electric vehicles. He carried out further, post-doctoral research on supercapacitors and graphene electrochemistry, at Imperial College London. Having also worked in the pharmaceutical industry, Foivos re-joined FEPS in late-2018 to conduct lithium-ion battery research.

The consortium will generate new knowledge, materials and engineering solutions, thanks to its dual focus on fundamental research at material and cell level, and an improved approach to system engineering. The project will address four key areas of research: cathodes; electrolytes; modelling platforms; and device engineering. In doing so, the LiSTAR consortium is seeking to enable rapid improvements in Li-S technologies, with the aim of securing the UK as the global hub for the research, development and deployment of this emergent technology.
The High Power Material Hybridised Battery (HiPoBat) project proposed a novel battery hybridised with high power electrode material at micro- and nano-level, with self-regulated voltage to a high and wide plateau, improved safety and prolonged lifetime. Innovative materials were designed and manufactured in this project so that synergetic effects of high power and high energy material features raised both power and energy density above the sum of the individual components. HiPoBat cells were fabricated, tested and subjected to many iterations of fine-tuning of material design and manufacture, also with the help of modelling and simulations. At the moment, the technology is undergoing scaled-up, to large prismatic cell level.
The aim the project was to use a coordinated approach that by simultaneously developing a suite of processing approaches (from emulsification, 3D printing, layer-by-layer deposition, aerogels) defined and addressed the many common scientific and engineering issues and was aimed to generate a synergistic effect that would push technological development.
The aim of project AUTOSUPERCAP was to develop supercapacitors of both high power and high energy density at affordable levels by the automotive industry, and of higher sustainability than many current electrochemical storage devices. There were several issues to achieve a high performance/low weight power system that not only had to be addressed by various groups of scientists and engineers but those issues had to be analysed and processed in an integrated framework.
This project investigated inkjet printing techniques for the fabrication of organic PV cells. It also explored the change of substrate temperature or charging to create transverse orientation and transverse needle-structure in PEDOT:PSS and other polymeric layers, as well as transverse orientation of multiwall carbon nanotubes (MWCNTs), and was aimed to improve PV cell performance.
The aim of the project was to abricate supercapacitor/EDLC cells with carbon-based fibrous and/or woven carbon fabric electrodes, utilising lithium/gel polymer electrolytes. The feasibility of combined improved performance and its correlation to carbon nanotube penetration into the carbon fabrics, was thoroughly investigated and reported.
