Proton‐conducting hydrogel electrolytes with tight contact to binder‐free MXene electrodes for high‐performance thermally chargeable supercapacitor

Carbon Energy, Volume 6, Issue 11, November 2024.
A thermally rechargeable supercapacitor (TCSC) that contains proton‐type hydrogel electrolyte and Ti3C2Tx MXene@PPy electrode is fabricated. The TCSC device exhibits a large thermal power of 35.2 mV K−1 at 50% relative humidity based on the Soret effect and the stable thermovoltage output of ∼200 mV under different time scenarios.
