摘要: 锂离子电池已成为重要的电化学能源储存设备,其性能的评估与监测对实际应用有着重要的指导意义。锂离子电池电化学反应模型是评估电池性能的有效手段。本文介绍了文献中依据电化学反应、离子扩散及电迁移过程建立的原始物理模型,通过引入电极副反应,两相反应,应力和能量等因素,进一步发展的锂离子电池电化学反应模型。较详细的说明了这些模型的电池充放电过程、锂离子浓度分布、电流分布、电极材料荷电状态、应力及循环容量衰减等模拟在电池实际运行中的应用。简要的介绍了物理模型的数学处理和简化,比较了各种处理方法的优缺点。

关键词: 锂离子电池, 电池反应模型, 循环容量衰减, 应力模型

Abstract: Lithium ion battery has become an important and popular electrochemical device for energy storage.Suitable evaluation and understanding of electrochemical performance and state of charge play a key role in the applications of lithium ion batteries.Construction and utilization of engineering modeling for lithium ion batteries is an effective way to fulfill this target.In this paper,engineering models of lithium ion batteries based on electrochemical reaction,ionic diffusion and migration are introduced.The emphasis is placed on the development of engineering models by the introduction of side reaction,phase transition,stress and energy.The applications of engineering models in such simulations as charge-discharge,concentration distribution,current distribution,state of charge,stress and capacity fading are particularly presented.The mathematical treatments and simplifications are also briefly described.

Key words: Lithium ion batteries, Battery reaction modeling , Cyclic capacity decay, Stress model
