建立了基于第一性原理的锂离子电池充放电模型，用于模拟锂离子电池的容量衰减。该模型是基于活性锂离子的损失，由于溶剂还原反应和阳极膜电阻的上升。定量地研究了交换电流密度、放电深度、充电结束电压、膜电阻和寄生反应过电压等参数的影响。该模型通过控制放电时间来控制所需的DOD，并估计作为循环数的函数的放电电压的结束。
A first-principles-based charge-discharge model was developed to simulate the capacity fade of Li-ion batteries. The model is based on the loss of active lithium ions due to solvent reduction reaction and on the rise of the anode film resistance. The effect of parameters such as exchange current density, depth of discharge (DOD), end of charge voltage, film resistance, and the overvoltage of parasitic reaction were studied quantitatively. The model controls the required DOD by controlling the discharge time and estimates the end of discharge voltages as a function of cycle number.
