Abstract
En 中文
The energy consumption has always been a core concern for modern economic society. However, industrial processes, automotive exhaust, and biological activities all emit a significant amount of unused waste heat, how to harvest this waste heat is crucial to the energy crisis. Thermoelectric conversion, as a green technology that directly converts heat into electricity, has garnered wide attention. In recent years, ionic thermoelectric (i-TE) materials have been vigorously developed due to their high Seebeck coefficient, flexibility, stretchability, and environmental friendliness compared to traditional electronic thermoelectric (e-TE) materials. In comparison to the longstanding research history of e-TE thermoelectrics, the i-TE thermoelectrics are still in infancy of expanding the upper limit at material level over the last decade. Here, the review systematically and carefully summarizes the i-TE materials from the perspectives of the basic concepts, classification of current i-TE materials, and performance optimization strategies. And the application of i-TE materials is further introduced. Finally, we summarize the advancements in i-TE development and propose the challenges and problems that need to be addressed in future research. This review provides additional insight in selection of active base materials and design concepts for i-TE materials evolution.
