a, b Optimized thermopower (Se) (a) and electrical conductivity (b) for the FTGA induced by different structures and additive materials. Data are presented as mean values ± s.d. For the measurements of Se and electrical conductivity, n = 3. c Property comparison of the electrical conductivity versus thermopower (Se) for various quasi-solid thermogalvanic thermocells. d–f Output voltage-current curves and their corresponding power densities at various temperature difference (ΔT) (d), corresponding maximum power density (Pmax) and specific output power density (Pmax/ΔT2) (e), and thermal energy conversion efficiency (η) and the Carnot-relative efficiency (ηr) (f). The cold side was fixed at 298 K. g Working mechanism of the enhanced thermopower in FTGA system through the selective crystallization of Gdm+ with [Fe(CN)6]4−. h Schematic solvation shell structures of [Fe(CN)6]3− and [Fe(CN)6]4− in FTGA.
