Current and emerging energy storage devices need to be enhanced to cope with the energy and power density requirements of different applications. Electrochemical models are helpful tools for the development and redesign of existing Li-ion batteries as well as to support more innovative ... Per saperne di più
This report explores the utilization of COMSOL® to investigate material properties and perform finite element analysis in solid-state batteries. Over the years, the increase of energy density in Lithium-Ion batteries has begun to plateau. The impact of mainstream consumer electronics ... Per saperne di più
Due to the rapid growth of the electromobility market much effort currently is being put into investigating electric vehicle batteries. Optimizing the microstructure of the cell components is playing an important role in extending range, enhancing fast charging capabilities and reducing ... Per saperne di più
This presentation summarizes the digital twin (DT) concept and how it can be implemented in COMSOL Multiphysics®. Concepts such as real and virtual spaces, high-fidelity models, and lightweight models are explained in the context of DTs. Per saperne di più
Large format Li-Ion battery cells (LIBC), often employed in electric vehicles (EV), show notable gradients in current and temperature distribution. This inhomogeneity can influence the cell’s safety and accelerate battery aging. It is, however, difficult to determine the local ... Per saperne di più
A lithium-ion battery comprises of two intercalating electrodes separated by a membrane, sandwiched between aluminum and copper current collecting plates. The battery performance depends upon several parameters and its operating conditions. In this work we developed a model for a lithium ... Per saperne di più
A thermal model to predict the heat generation during the charge and discharge of a battery pack is an essential tool to manage the thermal behavior, performance and life of the batteries. In this work, a battery cell is modeled in COMSOL Multiphysics® using the Batteries and Fuel Cells ... Per saperne di più
In this work the coupled electrochemical-thermal model for a lithium-ion battery (LIB) based on porous electrode theory has been extended with contributions coming from exothermic side reactions based on an Arrhenius law to model abuse mechanisms, which could lead to a thermal runaway. ...
