Figure 7. (A) Schematic of 4-stage charging-discharging cycle of TDC made of NaOH-PEO electrolyte and Au/CNT electrodes at a ΔT = 16 K (R_load = 100 kΩ). (B) V_oc of NaO-[CH2-CH2-O]_n-Na TDC during charging and discharging by applying a periodic heating source. (C) The charges being transferred during charging (black squares) and discharging (red circles) at different ΔT (R_load = 100 kΩ). (D) Schematic of a TDC made of PSSH polyelectrolyte and PANI electrodes. (E) Redox reactions of PANI during charging and discharging processes (switching between emeraldine salt and leucoemeraldine base). (F) α and electrical conductivity of PSSH TDC at various humidities and measured at different configurations, i.e., in-plane and out-of-plane. (G) 3-stage charging-discharging cycle of PSSH TDC at a ΔT = 5.3 K (R_load = 1 kΩ). (A-C) Reprinted with permission Ref.^[17]. Copyright 2016, The Royal Society of Chemistry.
