论文摘要
我们提出了一种动力学理论，即在电池中存储的化学能如何产生电动力（EMF）。在这张照片中，电池的半电池充当发动机，从其潜在的化学不平衡中循环提取工作。我们表明，电极 - 电解质界面处的双层可以表现出快速的自振荡，从而泵送电流，从而解决了化学能将化学能持续转化为等于EMF乘以分离电荷的EMF乘以。我们建议在包括电池在内的各种电化学细胞中观察到的这种机制与缓慢的自我振荡之间的联系，以及在将超声施加到半细胞上时观察到的电流的增强。最后，我们提出了对该动力学理论预测的更直接的实验测试。
We propose a dynamical theory of how the chemical energy stored in a battery generates the electromotive force (emf). In this picture, the battery's half-cell acts as an engine, cyclically extracting work from its underlying chemical disequilibrium. We show that the double layer at the electrode-electrolyte interface can exhibit a rapid self-oscillation that pumps an electric current, thus accounting for the persistent conversion of chemical energy into electrical work equal to the emf times the separated charge. We suggest a connection between this mechanism and the slow self-oscillations observed in various electrochemical cells, including batteries, as well as the enhancement of the current observed when ultrasound is applied to the half-cell. Finally, we propose more direct experimental tests of the predictions of this dynamical theory.
