During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... 詳細を見る
In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed by finding an optimal catalyst ... 詳細を見る
Maximizing product yield is a main task in chemical reaction engineering. This can be especially challenging if the desired product, once formed, can be consumed by further reactions. This example investigates such a series reaction as it occurs in a tubular reactor. You will start by ... 詳細を見る
This app demonstrates the usage of a surrogate model function for predicting the rate capability of an NMC111/graphite battery cell. The rate capability is shown in a Ragone plot. The surrogate function, a Deep Neural Network, has been fitted to a subset of the possible input data ... 詳細を見る
Mass transport limitations within thin crevices can often result in the local electrochemistry to differ significantly between the crevice opening (mouth) and end (tip), and as a result of the differences in local chemistry, corrosion may occur. This example models crevice corrosion of ... 詳細を見る
This example treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow. The equations that are solved are the ... 詳細を見る
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... 詳細を見る
This example demonstrates the Lithium-Ion Battery, Single-Ion Conductor interface for studying the discharge of a lithium-ion battery with solid electrolyte. The geometry is in one dimension and the model is isothermal. The behavior at various discharge currents and solid electrolyte ... 詳細を見る
Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a starting point for carbon-carbon coupling reactions. ... 詳細を見る
The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the ... 詳細を見る
