The earlier work in our group has established that natural convection plays a dominant role in SLRFB. We used it to run a battery in which interestingly, the contents are agitated for brief spells when no current flows through it. The present work focuses on electrode configurations ... Read More
SOFC is a high temperature electrochemical device known for its fuel flexibility. Apart from using pure hydrogen, it can utilize CO (carbon monoxide), CH4 (methane) or any other higher hydrocarbon. Since methane is highly researched hydrocarbon fuel, it was chosen to start with. The most ... Read More
Optimization of a typical electrochemical system with insulating shields is considered in this work, which objective is to reduce the current peak due to singularity and smooth the current density distribution along electrode surface. Moving mesh method was adopted to allow change in ... Read More
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 ... Read More
We develop a porosity-optimization problem to improve the electrochemical reactions taking place in hydrogen fuel cells. We introduce a mathematical model, which involves a system of conservation laws defined in a porous space domain. Our goal is to find the domain's optimal porosity ... Read More
Sacrificial metallic coatings (e.g. Mg-Rich Primer [MgRP]) have been evaluated for protection of aircraft aluminum alloy AA2024-T351 in marine immersion and atmospheric conditions. MgRP is designed to create a galvanic couple between the Al substratum and the Mg pigment in the primer. ... Read More
At the Technische Universität Chemnitz several academic institutions work on aluminum matrix composites (AMCs) within the Collaborative Research Centre SFB 692 HALS. Besides the development and analysis of these materials one main task is finishing machining of AMCs by an electrochemical ... Read More
Vehicles with battery as energy storage fascinate more and more people. Meanwhile, more questions are surfaced – How to ensure a safe operation of the battery package? How long could the cycle life of a battery package reach? Can a battery package be operated in any environmental ... Read More
This paper is about the influence of the diffusion coefficient when simulating mixed electrode materials. The results show that when simulating dynamic behavior of a lithium ion battery cell with mixed electrode material the diffusion coefficients is very important. Read More
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. ... Read More
