| Course description |
|
These new “polymer electrolytes” are recently winning interest as solid-state alternatives to liquid electrolytes for electrochemical device applications, which range from high-energy density rechargeable batteries to solar cells, ion sensors and electrochromic displays. Above all, secondary lithium batteries based on polymer electrolytes have the capabilities of outstanding performance in terms of easy processibility, mechanical stability, reliability and safety (non flammability and leakage). Solid polymer electrolytes (SPEs) are new electrolyte materials which consist of salt (ion source) and polar polymer such as polyether. In this lecture, you review the basics of polymer materials science learned in the undergraduate lectures. The lecture focuses on SPEs and proceeds fundamentals of history, structures/species, industrial needs and applications. You learn the mechanism of dissociation of salts, diffusion phenomenon, measurement techniques and recent research on SPEs. |
| Expected Learning |
| You can understand the basis of SPEs, especially material types, configurations for the energy storage device such as a lithium ion secondary battery and the principle of operation. |

| Refer to the books on polymers (such as Fiona M. Gray, Solid Polymer Electrolytes 〜Fundamentals and Technological Applications〜, VCH Publishers (1991), Fundamentals of Polymer Sciences and Electron Functional Polymers, etc.) in the library |
| Assessment/Grading |
| The grade evaluation in this online class is premised on all attendances, and comprehensively evaluates the attitude to learn, reports, and online tests. Standard study time set by our university is required to get the grade. Grade will be given according to the following criteria by comprehensive evaluation: S: 90 points or more, A: 80 or more and less than 90 points, B: 70 or more and less than 80 points, C: 60 or more and less than 70 points. |
| Message from instructor(s) |
| The SPEs have already used for batteries of laptop computers as in the gel state. From the viewpoint of electrical properties of polymer, there are unexpectedly many products applying piezoelectric and conductive polymers. Please try to learn hard to understand electric properties of polymer. |
