Abstract
Battery electrodes experience complex redox reactions upon cycling. Probing these electrode materials’ intricate phase behaviors is thus a prerequisite for a mechanistic understanding of their functionalities.  However, a fundamental study of these systems remains a practical challenge as their electrochemical reactions are often complicated by the formation of nanoscale/amorphous phases or structural defects such as distortion and disorder. These mechanistic and structural complexities give rise to significant challenges in characterisation, particularly on an atomic level. To combat these challenges, modern characterisation methodologies centering on pair distribution function (PDF) technique in combination with a variety of advanced analytical approaches will be presented via case studies of several electrode systems. The results offer significant insight from an atomic level upwards, helping to direct future efforts towards better materials design for improved device performances.
 
Biography
Dr Xiao Hua is currently a Faraday Institute Research Fellow working with Prof Serena Corr at the University of Sheffield. He obtained his PhD on the topic of electrode materials characterisation under the supervision of Prof Clare Grey at the University of Cambridge. Soon after completing his thesis, he joined Prof Ullrich Steiner’s research group at the Adolphe Merkle Institute to develop novel synthesis method for the preparation of mesoporous electrode materials. He was later awarded the Marie Curie Fellowship to work with Prof Andrew Goodwin at the University of Oxford to advance methodologies in the study of the local structures of functional materials.
