of electric vehicle ■

Because Lithium ion batteries have a high voltage and high energy density, lithium-ion battery have been intensively studied in order to meet the ever-growing demands of technologies ranging from electric vehicle and portable devices to grid-scale energy storages. However, since Lithium ion batteries use a flammable organic liquid electrolyte, there is a risk of explosion or fire. Safety is one of the most urgent concerns associated with further advances in next-generation high-energy batteries, making solid electrolytes among the most promising candidates to replace flammable and potentially dangerous liquid electrolytes. Because of these issues, all-solid-state lithium batteries have been proposed as a fundamental solution.

All-solid-state batteries never use any liquid cell components. Instead of using organic electrolyte, a lithium ion conductive ceramic, known as a solid electrolyte like poly-acrylonitrile(PAN), poly-vinylidene fluoride and
poly-ethyleneoxide, is used. Unfortunately, the ionic conductivity of a polymer electrolyte is, at a given temperature, at least 100 or 1000 times less than in a liquid or the better ceramic electrolytes.

For this reasons, our lab is going to research to develop high ionic conducting polymer consisted of silicon and carbon chain
