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.

电子热电学使用半导体将废热转化为电。例如，这是美国国家航空航天局（NASA）使用的一项既定能源生成技术，用来为火星流浪者供电。但是，由于较小的温度差异发电量较差，因此它并不适合低级废热恢复。离子导体会产生更大的热电压，并且更适合于近乎室温的运行。但是，它们不能以相同的操作方式使用，因为这将需要连续的离子流。提出的创新解决方案是将离子导体与一个储能系统搭配，该储能系统将离子电位转换为电子电位。该提案将研究新型的离子热电发电设备，该新型离子热电器发电设备由夹在包括超级电容器和插入材料在内的两个能量储存的离子导体组成。这是一种新颖的方法，目的是恢复低度废热，增加工业过程的可持续性并减少碳排放。
