Asian society for solid state ionics (ASSSI) started holding Asian Conference on Solid State Ionics (ACSSI) as biennial event since 1988 beginning at Singapore. Since then, this chain of conference has been held in different Asian countries. Though it is an Asian conference, scientist and intellectuals from all over the world take active participation in this event making it truly international in technical content and quality of interaction. Present ACSSI is the 16th in the chain of ACSSI conferences. This is the 4th time, this conference is scheduled to be held in China and for the first time in the eastern part of China at Shanghai under the banner of Shanghai Institute of Ceramics, Chinese Academy of Sciences and Tongji University. This conference aims to hold high quality technical deliberations by inviting accomplished expert speakers in the subject area to provide and develop clarity of subject understanding among the junior researchers and young students. This conference will be a unique opportunity for budding scientists and youngsters for understanding the subject fundamentals important to analyze the pros and cons of the ionic materials for technological applications in devices. This knowledge is extensively utilized also to protect and/or predict the lifetime of structural materials in harsh operating conditions to improve the performance reliability when used as components in devices. Presently, this research area is very important for wider scientific community comprising physicists, materials scientists, chemists, technologists and engineers belonging to academia, R & D institutions and manufacturing Industries and hence, highly relevant for socio-economic growth and society.
