Abstract

A type of functional material known as a thermoelectric material has the capacity to transform both heat and electric energy. Low-grade heat energy (heat less than 130 �C) may be converted into electric energy. Ionic thermoelectric materials perform better than conventional electrical thermoelectric materials. The See beck coefficient has strong application prospects in compact thermoelectric generators and solar power generation because it can create ionic thermoelectric potential that is 2-3 orders of magnitude larger than that of electronic thermoelectric materials. Ionic thermoelectric materials may be classified into ionic thermoelectric materials based on the Soret effect and thermocouple effect, according to the thermoelectric conversion mechanism. In recent years, there has been significant advancement in the study of ionic thermoelectric polymers, a novel family of materials with considerable potential for use in low-grade waste heat harvesting. In this work, we provide a brief overview of the operation of such materials, the key scientific developments, and the key performance evaluation standards. Ionic conductive polymer and ionogels are two categories of polymer-based ionic thermoelectric materials that we investigate. We also look at the more typical ionic liquid electrolytes as a comparison.
