| Outline of Final Research Achievements |
Thermo-electrochemical cell, or thermocell is an electrochemical system that generates electric power from temperature differences by utilizing the thermal responsiveness of various redox equilibriums. With the support of this grant, we demonstrate novel thermocells that utilizes the thermal responsiveness of various molecular sciences.First, we created a field of "supramolecular thermocell", which based on the host-guest chemistry of redox-active compounds. A variety of host-guest systems were designed and demonstrated, and summarized into a review. Second, we demonstrated a thermocell based on the difference of ionic conductivity in ionic solids. Third, we studied thermocells based on the LCST phase transition. Other thermocells based on proton-coupled electron transfer reactions or interaction of micelles were also investigated.

| Academic Significance and Societal Importance of the Research Achievements |
本研究扱った熱化学電池は、申請時には非常にマイナーなデバイスであったが、我々の研究や、中国・韓国・オーストラリアの研究の進展もあって今では盛り上がりを見せている。実用化に向けた本格的な研究開発も始まっており、時宜をとらえた提案を支援頂き、本分野に日本の存在感を示すことが出来た。熱化学電池の研究の中でも我々のアプローチは超分子化学を用いるという点で独創的であり、注目を集めている。また熱化学電池の視点から検討することで、電荷の違いを認識するホスト材料、分子間相互作用の相転移といったコンセプトに至っており、超分子化学の展開という観点からも興味深いと考えている。
