ASTICO is a dual-partners project (including an international collaboration) addressing a key unmet meet need for the next generation of Ionic ThermoElectric SuperCapacitors (ITESC). Such an outcome can be realized through the development of 2 building blocks: (i) electrode materials combining both multiscale and controlled porosity (macroporous p/n type Electronically Conducting Polymers (ECP) filled by mesoporous Covalent Organic Frameworks) along with (ii) solid-states polymeric ionic liquids (PIL). Our first hypothesis is that the temperature gradient generated between two electrodes - exhibiting multi-scale porosity - will improve the thermal gradient and boost the thermodiffusion of electrolyte ions towards the interface, hence maximizing their adsorption with a concomitant EDLC/pseudocapacitive effect. As the second hypothesis, the difference in mobility of anions and cations can be significantly amplified if one of the charged species is immobilized onto polymeric chains while the other remains free. Our choice is to develop anionic PILs and cationic PILs in which one charged species is immobilized while the other free to move and vice-versa. We expect the better thermodiffusion process, hence the ionic Seebeck coefficient (iS) will be exalted compared to the best state-of-the-art known performance (iS=26.1 mV.K-1 for free Ionic liquid/PVDF mixture). After achieving strong understanding of the individual components, the associations of electrode material + PILs building blocks in a two-electrode configuration will give birth to the first All-Solid-state ThermoIonic SuperCapacitOr.
