LAB and RESEARCH
The Hardwick Group laboratory has two Renishaw Raman microscopes, used to investigate the structural changes of electrode materials.

HARDWICK GROUP LABORATORY AT THE University of Liverpool
The Hardwick Group laboratory in the Stephenson Institute for Renewable Energy at the University of Liverpool, has two inVia Renishaw Raman microscopes, used to investigate the structural changes of battery materials over charge discharge cycles. In addition, the laboratory has glovebox facilities for production of material electrodes and construction of cells for subsequent Raman and X-ray investigations.
The XMaS beamline at the ESRF is designed to perform high resolution XRD and XAS measurements.

The University of Liverpool, along with the University of Warwick manages the XMaS beamline, based at the European Synchrotron Radiation Facility (ESRF), in Grenoble, France. The beamline has been designed to perform high-resolution X-ray diffraction (XRD) and X-Ray absorption spectroscopy (XAS), primarily for studies of materials science over an energy range of 2.1–40 keV in a focused monochromatic beam mode. Future plans for the beamline include the integration of a Raman system for combined X-ray and Raman measurements.

The high performance inVia Raman spectrometer, with a research grade microscope is used to measure battery materials, aiding in the identification of suitable materials, determination of their structures, and detection of changes in the material structure when measured ex situ during charge discharge cycles, by observing and comparing full spectra and individual Raman bands.
The XMaS instrument includes a Huber 6 circle non-magnetic diffractometer and multiple detectors to perform XRD and XAS measurements.

The heart of the XMaS instrument is the Huber 6 circle non-magnetic diffractometer. This instrument can perform high resolution diffraction, scattering in both horizontal and vertical geometries. Also, a whole suite of detectors can be mounted onto this versatile instrument to perform XAS in both fluorescence and transmission modes. The X-ray beam arrives from the right of the image and passes through various beam conditioning components to the diffractometer to the left of the image.

laurence Hardwick
Laurence Hardwick is Professor of Electrochemistry and Director of the Stephenson Institute for Renewable Energy within the Department of Chemistry at the University of Liverpool. He received his MChem in Chemistry in 2003 from the University of Southampton and PhD in Chemistry from ETH-Zurich in 2006. Before joining Liverpool in 2011, he spent his postdoctoral time working at the Lawrence Berkeley National Laboratory and at the University of St Andrews investigating Li-ion battery electrode degradation mechanisms, lithium diffusion pathways through carbon and the chemical and electrochemical processes in Li-air cells.
His recent work has focused on the development of advanced in situ electrochemical surface enhanced infrared and Raman methodologies that examine electrochemical reaction mechanisms on a variety of electrodes interfaces which assist in our understanding on the function of metal-air and Li-ion batteries.

Yvonne Grunder joined the Department of Physics and the Stephenson Institute for Renewable Energy in October 2013 as a Royal Society University Research Fellow. In 2008 she obtained her PhD in Physics, which was carried out at the European Synchrotron Radiation Source in Grenoble (France), from the Technische Universität Berlin. She then took up postdoctoral positions, from 2008-10 at the Christian-Albrechts-Universität in Kiel (Germany) and from 2010-13 at the University of Manchester. Her research interests are focused on atomic scale understanding of the structure and reactions at electrochemical interfaces

Grace Elliott Sherratt is a PhD student in the Hardwick Group in the Stephenson Institute for Renewable Energy within the Department of Chemistry at the University of Liverpool, investigating combining Raman and X-ray techniques in operando for battery material characterization. She initially aims to bring together X-ray measurements of electrode materials, obtained on the XMaS beamline, with Raman measurements taken in Liverpool, working towards a combined operando system.

Paul has been working on the XMaS beamline in Grenoble since 1996. He has been part of a team developing x-ray instrumentation and sample environments for use on the beamline and many of these developments have been used at other facilities or commercialized. During the last five or so years, he has optimized the XMaS beamline to enable high quality X-ray Absorption Spectroscopy (XAS), in the energy range 2.1-40 keV to be acquired, whilst also being able to perform high resolution X-ray diffraction (XRD), that can to be easily measured in a wide range of sample environments.
