In situ investigation of the formation mechanisms of advanced materials during their preparation and subsequent structural transformation, together with their electronic transitions during operation, offers insights into the design of new materials with improved performance for energy conversion and storage systems. First a brief introduction to in situ spectroscopic techniques will be given, this will be followed by a discussion of the use of in situ spectroscopies to elucidate the formation and operational mechanisms of several advanced materials for energy conversion and storage reactions – for example the formation mechanisms of bimetallic nanoparticles (b-NPs) for energy conversion studied by in situ X-ray absorption spectroscopy (XAS). Such approaches allow the monitoring of changes in the alloying extent and surface composition of b-NPs, during the course of synthesis, both of which are pivotal in energy conversion and catalytic reactions. I will also report in situ spectroscopic observations of the structural transformation and electronic transitions of electrode materials and the formation mechanisms of the solid-electrolyte-interphase (SEI) on electrode surfaces during energy storage reactions. By the use of such spectroscopic methods as discussed here our understanding of the charge-discharge and SEI formation mechanisms of electrode materials in battery systems can be advanced in a rational manner to improve the performance of energy storage systems.
