Electronic thermoelectrics use semiconductors to convert waste heat into electricity. This is an established energy generation technology, for example, used by NASA to power the Mars Rovers. However, it is not very suitable for low-grade waste heat recovery due to poor power generation from small temperature differences.Ionic conductors generate much larger thermal voltages and are better suited to near room temperature operation. However, they cannot be used in the same mode of operation as this would require a continuous flow of ions. The innovative solution proposed is to couple the ionic conductor with an energy storage system that converts the ionic potential to an electronic one.This proposal will investigate novel ionic thermoelectric power generation devices consisting of an ionic conductor sandwiched between two energy stores, including supercapacitors and insertion materials. This is a novel approach targeted at recovery of low-grade waste heat, increasing the sustainability of industrial processes and reducing carbon emissions.

电子热电利用半导体将废热转化为电能。这是一项成熟的能源发电技术，例如，美国宇航局使用它为火星漫游者提供动力。然而，由于温差较小，发电效果较差，因此不太适合低品位余热回收。离子导体产生更大的热电压，更适合在接近室温的情况下运行。然而，它们不能用于相同的操作模式，因为这需要连续的离子流。提出的创新解决方案是将离子导体与能量存储系统耦合，将离子势转换为电子势。该提案将研究新型离子热电发电装置，该装置由夹在两个能量存储之间的离子导体组成，包括超级电容器和插入式电容器材料。这是一种新颖的方法，旨在回收低品位废热，提高工业过程的可持续性并减少碳排放。
