Solid electrolytes have attracted enormous interest due to their wide applications in electrochemical devices such as sensors, and batteries. Solid electrolytes can be categorized into two different groups (ceramic or polymer electrolytes) depending on materials used. Ceramic electrolytes exhibit ionic conductivity higher than that of polymer electrolytes, however, brittle mechanical property of ceramic electrolytes is main obstacle for their easy application. In contrast, polymer electrolytes is flexible and can be easily applied to construct electrochemical devices, but their ionic conductivity is usually low. There have been numerous studies to increase ionic conductivity of polymer electrolytes by adding various plasticizers, and nanowires. To the best of our knowledge, nanowire’s shape-dependence on ionic conductivity has not been studied. Herein, we synthesized silver nanowires of various shapes (sphere, wire, triangle) and used them as additives to enhance ionic conductivity of chitosan-based polymer electrolyte. References [1] S. N.
