This study investigated the effects of alkali metal salts and electrode materials on the thermoelectric properties of poly(vinyl alcohol) (PVA)-based ionic thermoelectric generators (i-TEGs). Single-walled carbon nanotube (SWCNT) electrodes exhibited n-type behavior, whereas Cu electrodes predominantly showed p-type behavior, highlighting the importance of electrode/electrolyte interfacial interactions. Furthermore, a lateral i-TEG employing dissimilar electrodes was successfully developed, enabling the conversion of through-plane heat flow into in-plane electrical current.
