This project modeled an industrial chromium plating process for automotive components. The process was modeled via the COMSOL Multiphysics® Electrodeposition Module. The simulation examined the effect of solution conductivity, electrode spacing, and anode height utilizing a factorial design approach. A sensitivity analysis was used to study the effect of these variables on the thickness value at ...

The existing lithium ion battery model in COMSOL’s Multiphysics software is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. The existing lithium ion battery model in COMSOL 3.5a is extended by adding an energy balance and the temperature dependence of properties of ...

In this paper, the cyclic voltammetry behavior of Ferrocyanide/Ferricyanide, which is commonly used for electrochemical DNA detection experiment, was studied in the commercial EQCM-D setup (Q-sense) using the COMSOL Multiphysics. The model was established in a 3D geometry of QCM liquid cell. The simulation shows depletion of concentration of ferrocyanice following applied electrode ...

There is great interest in developing all-solid-state lithium-ion batteries. They are ideal micro-power sources for many applications in portable electronic devices, electric vehicles and biomedical engineering. It is known that all-solid-state lithium-ion batteries are often fabricated by thin film methods, with thicknesses in the range of a few micrometers. Since porous electrodes are not ...

Primary current distribution model for anodization of low-doped p-type silicon through a circular opening in frontside insulating mask is developed. The model is applied in two regimes of the process – pore formation and electropolishing – by definition of current density dependent functions of porosity and dissolution valence based on experimental results. As found also experimentally, ...

The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is supported by the results of our numerical simulation based of a Li+ battery in COMSOL Multiphysics® software. The ...

The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is based on the results obtained with a two-dimensional modelling approach. For both packs, the simulations ...

The presented model approach offers a computational efficient tool to analyze the influences of geometrical design details, material selection and operational conditions on the electro-thermal behavior of a full Li ion battery cell geometry. It considers typical aspects as anisotropic winding structure, electro-thermal coupling and nonlinear electrical characteristics for moderate computational ...

When it comes to study the behavior of the secondary batteries, physics-based models are more representative of the real behaviour than equivalent circuit models, especially for the estimation of the life and capacity fading. On the other hand, the complexity and computational cost of sophisticated physics-based models like pseudo two-dimensional (P2D) models justify the use of more simplified ...
