Title of Speech: Solid ionic conductor and solid-state battery
Abstract: Solid ionic conductors have attached tremendous attentions due to their potential capability to replace current organic liquid electrolytes. Furthermore, solid ionic conductors have also been studied for other type of energy storage devices through using their multi-functionality. One of examples is use of solid ionic conductors as Li ion conductor as well as separator to separate different types of liquid electrolytes in Li-air batteries. The key to success to use solid ionic conductors as electrolyte is ionic conductivity. However, most of current oxide-based solid ionic conductors possess about one to two orders of magnitude lower than those of liquid electrolytes. Therefore, increase in ionic conductivity is important. Moreover, Li ion transportation in current battery is through liquid-solid interface whereas the format of solid-state battery requires Li ions to transport through solid-solid interface, leading to large increase in the interface impedance. We at National University of Singapore and National University of Singapore Suzhou Research Institute have developed various type of solid electrolyte which have been used in Li-air battery and all-solid-state battery that can be operated at room temperature of 25oC. This presentation will provide an overview of current state of Li ion conductors and solid-state batteries.

Title of Speech: GOLD NANOWIRE-BASED E-SKIN WEARABLE SENSING TECHNOLOGY PLATFORM
Abstract: Next generation of electronic devices will be not only flexible but also stretchable, enabling applications impossible to achieve with existing rigid circuit board technologies. This needs new materials and new design principles. In this talk, I will discuss the Monash e-skin-based wearable technology platform including the electronic skin materials using gold nanowires, ionic liquid and bio-inspired design.

Title of Speech: Inorganic solid electrolytes for all-solid-state lithium batteries
Abstract: As a typical type of energy storage devices, lithium-ion batteries (LiBs) play a more and more important role in the modern life. However, organic polymer-based electrolytes are widely used in commercial Li-ion batteries, which may cause a large number of safety issues, considering the flammability, electrochemical stability, and leakage. Fires and explosions of LiBs have been reported throughout the world, and thus, safety has become one of the main obstacles for the wide application of LiBs. Therefore, the continued drive for high-performance lithium-ion batteries has imposed stricter requirements on the electrolyte materials and all-solid-state lithium batteries (ASSLiBs) have entered the field. In contrast to organic liquid electrolytes, solid inorganic ones show better thermal and chemical stabilities and also present a great advantage to the point that they can enable the use of high capacity electrode materials. Accordingly, a great deal of effort is underway to improve further the ionic conductivity and electrochemical/chemical stability of inorganic solid electrolytes and the solid electrolyte/electrode interface as well, thereby pushing them further for practical applications. In this talk, I will present our research breakthroughs in studying the preparation, structure, electrochemical properties, and potential applications of several important inorganic solid electrolytes, such as Li-oxide garnets like Li7La3Zr2O12 (LLZO), perovskite-type La2/3−xLi3xTiO3 (LLTO), and sulfide-based LGPS-type Li10.35Ge1.35P1.65S12.

Title of Speech: Mechanical Characterization of Materials by Digital Image Correlation Method
Abstract: Materials are often subject to forces (loads) when they are used. Understanding the mechanical behavior of materials is crucial for mechanical design and manufacturing. Currently, the displacement and strain fields of a deformed material can be measured by various methods such as interferometric method, strain-gauge method, and digital image correlation (DIC). Owing to the advantage of full-field, non-contact, macroscopic or microscopic scale, simple to use and cost effective for full-field displacement and strain measurements, digital image correlation techniques have been widely used in many fields in last decade. A self-designed DIC software program has been developed for years in Photomechanics Lab., NCKU. Considering the effect of correlation criteria, image distortion, and subset size on DIC vision system, a proper scheme is developed for obtaining more accurate measurement. Application of this scheme to mechanical characterization of semiconductor material, dental composite materials, and bio-tissue will be discussed and reported.
