چکیده

The accurate simulation of lithium-ion batteries is crucial for optimizing their performance, increasing their lifespan, and mitigating environmental concerns, as they play a vital role in powering electric vehicles, renewable energy systems, and portable electronics. This research presents a novel computational technique for simulating the internal processes of lithium-ion batteries, focusing on the electrochemical equilibrium and dynamics of these batteries. By leveraging the electrochemical method and simplifying complex differential equations through logical assumptions, the study develops a versatile tool for predicting the temporal and spatial distribution of electrode concentration, potential, and electrolyte dynamics in one dimension. The computational approach, executed in a C++ programming environment using computational fluid dynamics and the finite volume method, enables the simulation of diverse lithium-ion batteries.The research addresses the challenges posed by these batteries, including the quest for increased energy and power density, effective heat management, and control and monitoring complexities. By providing valuable insights into optimizing battery performance, this study contributes to the development of sustainable energy storage solutions.The proposed approach has the potential to shape a sustainable energy narrative, particularly in the context of all-electric and hybrid vehicles, and mitigating environmental concerns.
