The voltageplateau characteristics of lithium batteries in different working states are explored, and theconclusions are as follows:(1) Consistent with the trend of the overall discharge curve, the time and energy ofthe voltage plateau period decrease with the decrease of the ambient temperature and theincrease of the current rate.
The average temperature of the lithium-ion battery was calculated from the actual measured temperature and used to calculate the values of the temperature-related electrochemical parameters in the electrochemical model.
Combining it with the Arrhenius formula, the diffusion coefficient of lithium batteries was constructed as a function of battery temperature and lithium-ion concentration. Based on the proposed diffusion coefficient function, an electrochemical–thermal coupling model was established.
The specific experimental process is shown in Figure 2. First, put the lithium battery at −20 °C, −5 °C, 10 °C, 25 °C, and 40 °C ambient temperature for 10 h, and then charge it with a constant current of 1C to the end-of-charge voltage (4.2 V), and then switch to constant-voltage charging. Stop charging when the charging current drops to 0.05C.
The electrochemical model of lithium-ion batteries mainly consists of the following governing equations: the mass conservation equation for the solid and liquid phases, the charge conservation equation for the solid and liquid phases, and the electrode kinetics’ equation at the interface between the solid and liquid phases.
In addition to the thickness of lithium-ion battery electrodes, another important design parameter for battery electrodes is the volume fraction of active material. The active substances in lithium-ion batteries are closely related to their internal electrochemical reactions.
