Heat profile in an air-cooled cylindrical lithium-ion battery battery pack. The thermal model is coupled to electrochemical reactions and ion flow, which act as a heat source.
Batteries and fuel cells are being asked to perform in more challenging environments, with greater energy densities or power efficiencies, over longer lifetimes. These requirements are placing more pressure on these industries, and modeling and simulation is fast becoming one of the necessary tools for developing, designing, optimizing, and ensuring quality and safety of batteries and fuel cells during operation. Examples of systems that may be studied include lead-acid batteries, lithium-ion batteries, nickel metal-hydride batteries, solid oxide fuel cells (SOFCs), direct-methanol fuel cells (DMFCs), and proton exchange membrane fuel cells (PEMFCs).
The Batteries & Fuel Cells Module models the underlying electrochemical behavior in the electrodes and electrolytes of batteries and fuel cells. It allows you to investigate their performance for different operating conditions, design configurations, and deterioration due to different aging mechanisms. With this add-on module, you can simulate characteristics such as the transport of charged and neutral species, current conduction, fluid flow, heat transfer, and the nature and driving forces of electrochemical reactions at planar and in porous electrodes. Using this understanding of these characteristics, you can design and optimize the geometries and material choices of your system’s electrodes, separators, membranes, electrolyte, and current collectors and feeders with respect to performance, thermal management, and safety.
