Figure 3. Thermoelectrochemical performance optimization and power output characterization. (A) Thermopower and (B) ionic conductivity of PAAm and P(AAm-AMPS) electrolytes as a function of DMSO volume fractions; (C) Current density-voltage and (D) power density curves of the optimized PSD-10 electrolyte measured under different ΔT; (E) Maximum power density (Pmax) and the normalized power density (Pmax/ΔT2) under the corresponding ΔT; (F) Thermal conductivity of different hydrogel electrolytes. PAAm: Polyacrylamide; AAm: acrylamide; AMPS: 2-acrylamido-2-methylpropanesulfonic acid; DMSO: dimethyl sulfoxide.
