The Asian Society for Solid State Ionics (ASSSI) was conceived and founded in 1986 during a Workshop entitled "Materials for Solid State Batteries" held at the National University of Singapore. As one of the major activities of the Society, it was then decided to organize a series of biennial "Asian Conference on Solid State Ionics". The objective of the said conference being to bring together the concemed researchers from the Asian countries in order to exchange notes, ideas,foster friendship and collaboration and discuss future prospects. Even though,these biennial conference series are mostly attended by the scientists from the Asian region, consistently we have been having participation from our distinguished colleagues from Europe and USA as well.
