The study introduces polyethyleneimine as an additive in a thermocell, enhancing thermopower from 1.4 to 7.76 mV/K. It achieves long-term stability and scalability by enabling thermosensitive adsorption-desorption, selective reactions, and Manning condensation, converting low-grade heat to electricity efficiently.
