“…L TBL can be increased by decreasing the thermal dissipation rate from the electrode to the outside of the cell. In theory, an adiabatic condition can realize an infinitely large L TBL value, and Equation (3) can be simplified as Equation (4) (see Supporting Information for the derivations): ): references = a, [56] b, [58] c, [55] d, [58] e, [57] and f. [59] Notably, Equation ( 4) predicts that a large ΔT SS value over 1 K can be obtained under an ideal adiabatic condition (Figure S16, Supporting Information). To experimentally observe the effect of increasing the L TBL value, the entire ECP cell was covered with polystyrene foam to minimize the thermal dissipation from the cell (Figure S3, Supporting Information).…”

“…Typically, the VCR cycle shows COP values greater than 3, [54] and the commercial TEs show values between 0.5-1.5. [55][56][57][58][59][60] The COP of the ECP cell containing the static electrolyte can be calculated by Equation (5), which was derived from the equations originally developed for TEs. [51] COP =…”

“…A) Development of Δ T and the corresponding voltage change during the ECP cooling and heating cycle of the [Fe(CN) 6 ] 4−/3− cell, measured by the two‐wire sensing or the four‐wire sensing method. J = 15 mA cm −2 , L S = 11 mm, T = 312 K. B) COP values of the [Fe(CN) 6 ] 4−/3− cell obtained from two‐wire sensing or the four‐wire method, and their comparison with those values of the commercial TEs (Bi 2 Te 3 ): references = a, [ 56 ] b, [ 58 ] c, [ 55 ] d, [ 58 ] e, [ 57 ] and f.
