The evaluation of batteries under thermal gradients is essential for safety and longevity reasons, and to investigate power generation via the thermogalvanic effect. The thermogalvanic Seebeck coefficient of lithium metal (+ 1.0 mV·K^− 1) and solid lithium ferri/ferrocyanide intercalation electrodes (− 0.6 mV·K^− 1) were determined. The measured Seebeck coefficients of identical asymmetric cells containing both electrodes deviated from the expected values, having Seebeck coefficients which also varied as a function of thermal conditions (+ 0.7 to + 4.3 mV·K^− 1). This work demonstrates that the thermal responses of asymmetric battery assemblies are more complex than predicted based upon their individual half-cell performances in symmetric cells.

出于安全性和寿命的考虑，对热梯度下的电池进行评估是必不可少的，这对于通过热电流效应进行发电研究也至关重要。确定了锂金属的热电塞贝克系数（+ 1.0 mV·K ^-1）和固态亚铁/亚铁氰化锂嵌入电极（-0.6 mV·K ^-1）。包含两个电极的相同不对称电池的实测塞贝克系数偏离了预期值，塞贝克系数也随热条件而变化（+ 0.7至+ 4.3 mV·K ^-1）。这项工作表明，不对称电池组件的热响应比基于其在对称电池中的单个半电池性能所预测的要复杂得多。
