Mathematical Models for Life Estimation of Lithium-Ion Batteries

Recent advancements have stimulated strong interest in the use of lithium-ion (Li-ion) batteries for powering electric vehicles (EVs) and hybrid-electric vehicles (HEVs). However, the loss in discharge capacity with repeated cycling is still a considerable challenge for these energy storage devices. The capacity degradation of Li-ion batteries is caused by the formation of a solid-electrolyte interface (SEI) film and gas evolution at the anode and active material dissolution at the cathode. In this respect, we present simulations conducted using an experimentally validated model capable of quantifying the effects of SEI film and gas formation on the capacity degradation of mesocarbon microbead (MCMB) LiMn2O4 (LMO) cells. The developed model is capable of estimating the life of the battery, including the SEI film thickness, volume of gas, and reduction in electrolyte volume fraction at various currents. Further, the processes in Li-ion batteries are quite complex, as the electrochemical reaction, heat generation, and charge transfer are coupled to each other. In this scenario, thermal runaway occurs when the cell temperature exceeds the no-return temperature, above which an increase in temperature is irreversible. We will also present our preliminary attempts at developing a thermal model for the performance evaluation of commercial cells.

Parallel Minicourses - 1
Modeling Batteries and Battery Packs Minicourse

Learn how to effectively model batteries and battery packs using COMSOL Multiphysics®. In this minicourse, we will discuss the detailed electrochemistry approach and lumped model approaches to modeling batteries. With the help of the COMSOL Multiphysics® software, we will also demonstrate how modeling can be used for charge and discharge analysis, abuse modeling, and the thermal management of battery systems.

Structural Mechanics and Acoustics Minicourse

This minicourse will cover the rich physics involved in structural analysis and acoustics as well as the interactions between them. Interactive examples include transducers, speakers, microphones, SAW filters, smartphones, medical sensors, and many others. We will discuss the range of material models (linear and nonlinear) you can choose from; loading and support conditions; and linking between solids, shells, plates, and beams.

Parallel Minicourses - 2
CFD and Heat Transfer Minicourse

During this minicourse, we will walk you through an example of modeling fluid flow and give a quick overview of using the CFD Module for laminar, turbulent, and high Mach number flow; non-Newtonian, multiphase, and nonisothermal flows; and flow in mixers. You will also learn how to accurately model the thermal characteristics of systems that include heat transfer by conduction, convection, and radiation. In addition, we will discuss how you can model and optimize systems that include phase change, bioheating, electronic cooling, thermally induced stresses, and thin thermal barriers.

Modeling Electric Machines and High-Voltage Transmission Devices Minicourse

This session will discuss the details of modeling electric machines and high-voltage transmission devices using the COMSOL Multiphysics® software, along with various multiphysics aspects. We will focus on modeling electric and magnetic fields and on how to capture nonlinearity in magnetic materials. During this session, we will also explain how to model different types of transformers and electric motors, such as induction motors, permanent magnet motors, linear variable differential transformers (LVDTs), generators, alternators, magnetic gears, bearings, and more. In addition, we will discuss how to compute winding and core losses for thermal analysis in motors and transformers. See how electromagnetic forces can be coupled with structural mechanics and acoustics to predict noise in electric machinery.
