Abstract
A tertiary battery (TB) can be charged by heating or cooling via the difference in the electrochemical Seebeck coefficient α between the cathode and anode. Here, we investigated the battery resistance R and its effect on the performance of a laminate film-type Na1.48Co[Fe(CN)6]0.87 (Co-PBA)/Na1.76Ni[Fe(CN)6]0.94 (Ni-PBA) TB. We found that the charge-transfer resistance Rct and diffusion resistance Rdif are the dominant components of R, while the solution resistance Rs has a minor role. Regardless of the solute type, R varied inversely proportional to the Na+ concentration M. In a high-R TB, the thermal voltage VTB and discharge capacity QTB per unit weight of the total active material are significantly suppressed, which is quantitatively explained in terms of the voltage drop (IR, where I is current) during the discharge process.
