Rechargeable lithium-ion batteries are remarkable nominees for application into new large- scale energy storage requests, such as hybrid and electric vehicles, as a result of their high energy density. We present here a comprehensive dynamic model which is suitable for studying the charge and discharge systems in the Lithium-Ion Battery. The chosen geometry in this study is in one dimension and the model is isothermal. In this case carbon material represents the negative electrode and lithium manganese oxide (LiMn2O4 spinel) indicates the positive electrode. In addition, in the proposed model the diffusion coefficient of Li ions in its solid state and electrolyte, the electrochemical reaction’s rate constants, the thermal conductivity of the binary electrolyte rely on the temperature. In this investigation, COMSOL Multiphysics is utilized to investigate Lithium-Ion battery model reliant on dilute electrolyte principle and rapid diffusion of lithium in the electrode fragment. This modeling can offer appreciated understandings into the fundamental defect and ion transport properties of electrode materials at the atomic scale, which are vital for a full appreciative of lithium battery function. Modeling founding for a lithium-ion battery are presented and compared to experimental data. Good agreement exists for both charge and discharge between theory and the outcome of this study for numerous investigational cell configurations. This mathematical model specifies that the battery in its existent design is ohmically restricted.
