论文摘要
电池降解是随着时间的推移的降低，这是锂离子电池广泛部署的主要障碍之一。基于物理学的模型，例如基于Doyle-Fuller-Newman模型的模型，是理解和预测这种现象的宝贵工具。但是，对于实际应用，这些模型通常太复杂了，因此需要减少模型。在本文中，我们介绍了带有电解质和侧面反应的单个粒子模型，这是一种用电化学降解的简化模型，该模型已正式源自Doyle-Fuller-Newman模型，并使用渐近方法进行了侧反应。还针对三种方案（固体 - 电解质相间的生长，锂镀层和两种效果）的完整模型进行了验证，以较低的计算成本显示了相似的精度。结果的含义是双重的：简化的模型是简单而准确的，足以在大多数实际实用应用中使用，并且所使用的还原框架是强大的，因此可以扩展以考虑进一步的降解效应。
Battery degradation, which is the reduction of performance over time, is one of the main roadblocks to the wide deployment of lithium-ion batteries. Physics-based models, such as those based on the Doyle-Fuller-Newman model, are invaluable tools to understand and predict such phenomena. However, these models are often too complex for practical applications, so reduced models are needed. In this article we introduce the Single Particle Model with electrolyte and Side Reactions, a reduced model with electrochemical degradation which has been formally derived from the Doyle-Fuller-Newman model with Side Reactions using asymptotic methods. The reduced model has been validated against the full model for three scenarios (solid-electrolyte interphase growth, lithium plating, and both effects combined) showing similar accuracy at a much lower computational cost. The implications of the results are twofold: the reduced model is simple and accurate enough to be used in most real practical applications, and the reduction framework used is robust so it can be extended to account for further degradation effects.
