Abstract

To meet the ever-growing worldwide electric vehicle demand, the development of advanced generations of lithium-ion batteries is required. To this end, modelling is one of the pillars for the innovation process. However, modelling batteries containing a large number of different mechanisms occurring at different scales remains a field of research that does not provide consensus for each particular model or approach. Parametrization as part of the modelling process appears to be one of the issues when it comes to building a high-fidelity model of a target cell. In this paper, a particular parameter identification is therefore discussed. Indeed, even if Butler–Volmer is a well-known equation in the electrochemistry field, identification of its reaction rate constant or exchange current density parameters is lacking in the literature. Thus, we discuss the process described in the literature and propose a new protocol that expects to overcome certain difficulties whereas the hypothesis of calculation and measurement maintains high sensitivity.

用于锂离子电池电化学建模的新型反应速率参数化方法

为满足全球日益增长的电动汽车需求，需要开发先进的锂离子电池。为此，建模是创新过程的支柱之一。然而，电池建模包含在不同尺度上发生的大量不同机制，这仍然是一个研究领域，并没有为每个特定模型或方法提供共识。作为建模过程的一部分，参数化似乎是建立目标电池高保真模型的问题之一。因此，本文将讨论一种特定的参数识别方法。事实上，即使 Butler-Volmer 是电化学领域的著名方程，文献中也缺乏对其反应速率常数或交换电流密度参数的识别。因此，我们讨论了文献中描述的过程，并提出了一种新的方案，希望能克服某些困难，同时在计算和测量假设中保持高灵敏度。
