The Cutting – Edge Materials for Electrical Energy Storage and Efficiency Group is dedicated to the development of highly reliable, controllable and throughput deposition processes of next-generation materials (i.e. thin films, nanostructures and nanocomposites) for energy storage and efficiency technologies including fuel cells, batteries, capacitors and superconductors.
The Group offers growth manufacturing processes for pure/multi metals, alloys, oxides as well as carbon allotropes with:
Great degree of flexibility: Atmospheric Pressure Chemical Vapour Deposition (APCVD) system
Low cost: Spray Pyrolysis
High purity: Low Pressure Chemical Vapour Deposition (LPCVD) system
High-Yield & Up-scalable: Plasma Enhanced Chemical Vapour Deposition (PE-CVD) system
Substrate cleaning & modification: Ar/O2 Plasma source
In addition, the Group is offering material characterisation equipment for analyzing the properties of the materials developed by the above-mentioned growth equipment:
Structure: Fourier-transform infrared spectroscopy (Shimadzu)
Morphology: Scanning Electron Microscopy with Energy Dispersive X-ray analysis (JEOL 840)
Electrical: 2-point and 4-point probe conductivity/resistivity set-up
Electrochemical: Cyclic Voltammetry, Electrochemical Impedance Spectroscopy (AUTOLAB potentiostat/galvanostat)
Other: Contact angle measurement set-up, Photocatalytic measurement set-up, Electrochromic and thermochromic measurement set-ups, Shimadzu UV-VIS spectrophotometer, Ion chromatography, Gas chromatography
Services currently offered by the infrastructure: The scientific achievements of the growth manufacturing processes are summarized below:
Electroactive metal oxide (V2O5, VO2 (B), WO3, MnO2, α-Fe2O3) based structures suitable for the fabrication of electrodes for fuel cells, supercapacitors, Li+, Mg2+ batteries.
Metal oxide nano/microstructures (ZnO, TiO2, V2O5 and WO3) exhibiting significant photocatalytic action suitable for the degradation of gas and liquid pollutants.
Growth of thermochromic V1-xWxO2 layers with low transition temperature suitable for energy saving in buildings.
Growth of electrochromic WO3 layers with fast response and high coloration efficiency.
Our facilities are currently utilized by the Department of Chemistry (UCC), Department of Chemistry (Imperial College London), Department of Chemistry (University College London) and Luxembourg Institute of Science and Technology regarding the electrochemical characterization of their samples (V2O5, Doped V2O5, Si/Carbon Nanotubes/Stainless Steel, TiO2/Carbon Nanotubes/Stainless Steel and Perovskites). Through this collaboration, joint publications (e.g. Journal of Electrochemical Science and Engineering 10 (2020) 257, Molecules 25 (2020) 5558) and proposals have been recently submitted (Marie-Curie Research Fellowship), and others are in the submission process.
