Abstract
The efficient conversion of dissipated heat into useful electrical energy has emerged as a promising approach for sustainable energy technologies. Ionic thermoelectrics (iTEs) are particularly attractive because they generate substantial thermo‐voltages, effectively harvest low‐grade heat, and offer advantages such as cost‐effectiveness, easy scalability, and remarkable performance. Unlike liquid‐state platforms, quasi‐solid‐state iTEs exhibit properties that are critically governed by the polymer matrix and polymer‐ion interactions, which are closely related to the overall device performance. Consequently, the use of functional polymers effectively improves the characteristics and performance of quasi‐solid‐state iTEs. Therefore, this paper highlights the impact of the polymer matrix on performance and mechanical properties in iTEs from molecular‐, micro‐, to macro‐scale engineering.…
