Temperature adaptive self-regenerating ionic thermoelectric cycles for time domain thermal energy harvesting.

ABSTRACT: The rising demand for sustainable energy solutions has promoted significant interest in ionic thermoelectric materials, which convert low-grade waste heat into electrical energy through spatial temperature gradients. However, diurnal temperature variations, which offer potential for location-independent time-domain thermal energy, remain largely unexplored. To overcome the challenges of harvesting spatially limited thermal energy, this study presents an ionic thermoelectric cycle (t-ITC) designed for time-domain thermal energy harvesting, incorporating two gels with contrasting temperature coefficients. A temperature-adaptive self-regeneration (TASR) strategy is proposed to set the critical regeneration temperature (T_CR) at the midpoint of temperature fluctuations, facilitating
