Different models coupled to the electrochemical model for the simulation of lithium-ion batteries. Table 1 shows the main equations of the Doyle/Fuller/Newman electrochemical model that describe the electrochemical phenomena that occur in the battery components (current collectors, electrodes, and separator) during its operation processes.
An important component in battery devices is the separator, placed between electrodes, and for lithium-ion batteries, acts as the lithium-ion transfer medium between the electrodes, while providing mechanical stability, thermal resistance, and avoiding short-circuit of the battery.
Theoretical models are based on equations that reflect the physical and electrochemical principles that govern the different processes and phenomena that define the performance and life cycle of lithium-ion batteries. Computer simulation methods have encompassed a wide range of spatial and temporal scales as represented in Figure 3.
As the separator plays an essential role in the performance and safety of lithium-ion batteries, the recent theoretical simulation work for this battery component are shown, with particular emphasis on morphology, dendrite growth, ionic transport, and mechanical properties.
Computational simulation of lithium-ion batteries has a significant impact on the prediction of the performance of these energy storage systems as well as on the behavior and bonding of elements generated during their use.
A central to this rise is the widespread adoption of lithium-ion batteries (LIBs) as the energy storage solution in EVs . A critical component in ensuring the efficiency and safety of LIBs is the battery management system (BMS), tasked with monitoring and controlling the batteries .
