In this study, we optimized the electrode parameters of NaxCo[Fe(CN)(6)](0.88)/NaxCd[Fe(CN)(6)](0.99) tertiary battery, allowing it to achieve a discharge capacity (Q(cell)) of 4.9 mAh/g between 293 K and 312 K.
A tertiary battery, which is charged by temperature change, has two performance indexes: the thermally induced voltage (V-cell) and discharge capacity (Q(cell)). Among them, Qcell is determined by the electrode parameters such as charge coefficient [ss(+) (ss_)] of redox potential (V) and weight [m+ (m(+)(m(-))] of the active material in the cathode (anode). In this report, we optimized electrode parameters to maximize Q(cell) of NaxCo[Fe(CN)(6)](0.88)/NaxCd[Fe (CN)(6)](0.99) tertiary battery. By this optimization, Qcell reaches 4.9 mAh/g between 293 K and 312 K.
