Lithium-ion cells are high energy and high-power density electrochemical storage devices that are used throughout the automotive industry. As the climate around the world continues to change, the implementation and use of lithium-ion batteries will continue to increase. Thus, to ensure the best performance is achieved, a thorough understanding of the internal processes of lithium-ion cells and the effects of the arrangement of the systems in which they are incorporated is required. To achieve a deeper understanding of the electrochemical processes within a cell, an electrochemical aging model of a prismatic 131 Ah NCA/Gr lithium-ion cell is developed using COMSOL Multiphysics V6.2 ®.
