摘要
Abstract Tertiary battery (TB) can be charged by heating or cooling via difference in the electrochemical Seebeck coefficient α between cathode and anode. Here, we investigated battery resistance R and its effect on thermal cycle properties in laminate film type Na{ 1.48 Co[Fe(CN) 6 ]{ 0.87 (Co-PBA) / Na{ 1.76 Ni[Fe(CN) 6 ]{ 0.94 } (Ni-PBA) TB. We found that charge-transfer resistance R ct and diffusion resistance R dif are the dominant components of $R$ while solution resistance R s has minor role. Regardless of the solute type, R varied inversely proportional to the Na + concentration M. In high-R TB, the thermal voltage V TB and discharge capacity Q TB per unit weight of the total active material is significantly suppressed, which is quantitatively explained in terms of the voltage drop (= IR; I is current) during the discharge process.
