ABSTRACT

This chapter summarizes some experimental facts for the problems related to enhanced ion dynamics in porous and related materials along with the history of research of the LiI-alumina composite. Historical view of how the research in nanoionics has been developed is useful to understand what factors affect the problems and what kind of methods can be used. The chapter also summarizes experimentally relevant facts for the structures obtained from the coagulation of colloids/particles, where the importance of dimensionality of the systems in colloidal systems and gels is shown. Especially, attention is paid to nanoionics with enhanced dynamics and factors modifying ionic properties in nanostructured composites for suggesting problems to be examined by molecular dynamics simulations. For the development of the field of nanoionics, further research for the nanoscopic mechanism of the enhancement is expected and molecular dynamics simulation seems to be suitable for such treatments.
