The authors developed a physics‐based equivalent circuit model of a lithium‐ion battery (LIB) whose parameters are continually updated, reflecting the theoretical calculation results of the Butler‐Volmer equation, diffusion equations of the lithium‐ion and lithium, and Nernst equations of the liquid and solid phases. The developed model was applied to the charge/discharge simulations of an LIB, and the experimental and simulated results of constant current discharges and pulsed‐charge/discharge were found to be in excellent agreement. In particular, using the developed model, analyzing transient responses of the LIB derived from the transition of the electric double layer charging to the electrode reaction is possible. These results demonstrate that the electrochemical performance of an LIB can be calculated on a circuit simulator using the developed model.

在电路模拟器上运行的基于物理原理的锂离子电池模型

作者开发了一个基于物理的锂离子电池（LIB）等效电路模型，其参数不断更新，反映了Butler-Volmer方程，锂离子和锂的扩散方程以及Nernst方程的理论计算结果。液相和固相 将开发的模型应用于LIB的充电/放电模拟，发现恒流放电和脉冲充电/放电的实验和仿真结果非常吻合。特别地，使用开发的模型，可以分析从双电层电荷过渡到电极反应而衍生的LIB的瞬态响应。
