Tertiary battery, which can be charged by heating and/or cooling, is a promising energy harvesting device that performs energy conversion during the thermal cycle between low and high temperatures. Here, we investigated the performance of the Na _x Co[Fe(CN)₆]_0.87 (NCF87)/Na _x Ni[Fe(CN)₆]_0.94 (NNF94) tertiary battery made of paste-type electrodes between 10 and 50 C. Its performances, i.e. thermally-induced voltage (V _cell), discharge capacity (Q _NCF87) per unit mass of NCF87, and time constant (τ) when connected to an external resistance, are well reproduced by the temperature- and charge-derivatives of the redox potential (V) of the constituent cathode (NCF87) and anode (NNF94).

可以通过加热和/或冷却充电的三次电池是一种很有前途的能量收集装置，它在低温和高温之间的热循环中进行能量转换。在这里，我们研究了由糊状电极制成的 Na _x Co[Fe(CN) ₆ ] _0.87 (NCF87)/Na _x Ni[Fe(CN) ₆ ] _0.94 (NNF94) 三次电池在 10 到 50 C 之间的性能. 其性能，即热感应电压（V _cell）、单位质量 NCF87 的放电容量（Q _NCF87）和时间常数（τ ) 当连接到外部电阻时，由组成阴极 (NCF87) 和阳极 (NNF94)的氧化还原电位 ( V )的温度和电荷导数很好地再现。
