This research provides a reliable method for the analysis and evaluation of the charging and discharging characteristics of lithium batteries, which is of great value for improving the safety and efficiency of lithium battery applications.
As one of the key testing indexes for the performance of lithium battery, the testing of charging and discharging characteristics can directly show the capacity and performance of lithium battery. The advantages of lithium battery mainly have no pollution, no memory and large monomer capacity, which are widely used in various electronic products.
The temperature of lithium-ion cell and module has a significant impact on performance and ageing. Therefore, it is crucial predicting the temperature distribution and evolution of lithium-ion batteries. However, most of the electrothermal models consider a simplified cell geometry.
According to research experience, the temperature distribution of lithium-ion batteries is usually determined by changes in the internal heat flux of the battery, including the heat generated internally and its conduction to the external environment.
In order to improve the energy storage and storage capacity of lithium batteries, Divakaran, A.M. proposed a new type of lithium battery material and designed a new type of lithium battery structure, which can effectively avoid the influence of temperature on battery parameters and improve the energy utilization rate of the battery .
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.
