Modeling Electrochemical Processes in a Solid-State Lithium-Ion Battery

Bridget Cunningham | December 7, 2016

Traditional lithium-ion batteries use an electrolyte based on a flammable liquid solvent, which can cause them to catch fire if they overheat. In recent years, nonflammable solid electrolytes have been investigated as an alternative to improve battery design and safety. Optimizing this technology for industrial applications, however, requires a better understanding of the electrochemical processes inside the device. Simulation serves as a valuable tool for this purpose, helping to realize the use of solid-state lithium-ion batteries in the near future.

Food packaging is often composed of recycled materials, like newspapers or plastic, which may contain residual mineral oil inks. Traces of these potentially hazardous substances leftover from the recycled materials can migrate from the packaging to the stored food. To account for this, one research team developed a numerical model to analyze the migration patterns of mineral oil hydrocarbons for various packaging situations. Compared to experimental studies, their approach offers a more efficient and cost-effective way of optimizing food safety.

When designing a perforated well to recover oil and gas, choosing the right number of perforations with the appropriate properties is key. Too many holes and you run the risk of equipment failure or injury; too few and you decrease productivity levels. One way to achieve this balance and improve the safety and productivity of the recovery operation is to model fluid flow near the wells. Let’s see how the Application Builder makes this process even more efficient.

Environmental demands for greater fuel efficiency and lower emissions have sparked an interest in finding an alternative to traditional spark- and compression-ignition engines. While homogeneous charge compression ignition (HCCI) engines offer a viable solution, significant challenges like maintaining control of ignition timing still remain. With simulation tools like the COMSOL Multiphysics® software, you can analyze the combustion process of an HCCI engine and gain deeper insight into ways to advance ignition control.

Like many crops, the quality of dates is heavily impacted by agronomic practices. In Tunisia, for example, such elements have caused these soft edible fruits to become drier in nature. One approach to improving the quality of these dates is thermal processing, where the key unit of operation is hydration. Combining the power of experimental studies with simulation analyses, a team of researchers sought to optimize the hydration process in order to foster greater efficiency and reliability.

In any form of treatment, it is always desirable to minimize the level of discomfort that the treatment process causes patients, while ensuring overall safety and effectiveness. For diabetes patients, insulin injections remain an important form of treatment, but the process itself can be painful. With the help of multiphysics simulation, a team of researchers from the University of Ontario Institute of Technology sought to develop a MEMS-based micropump that could administer insulin injections in a safe and painless way.
