In a polymer electrolyte membrane fuel cell (PEMFC), water is produced at the cathode. The cell is also fed with water vapor via the inlet gas streams, in order to keep the polymer electrolyte membrane humidified. If the water partial pressure in the gas phase exceeds the vapor ... 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

The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... 詳細を見る

This example applies the Electrophoretic Transport and Laminar Flow interfaces to model isoelectric separation in a free-flow electrophoresis device. A stream containing six different ionic species is shown to be divided into pure component streams by means of migrative transport in an ... 詳細を見る

This model simulates the shape evolution of a microconnector bump over time as copper deposits on an electrode surface. Transport of cupric ions in the electrolyte occurs by convection and diffusion. The electrode kinetics are described by a concentration dependent Butler-Volmer ... 詳細を見る

Lithium-sulfur (Li-S) batteries are used in niche applications with high demands for specific energy densities, which may be as high as 500-600 Wh/kg. The chemistry is fairly complex, since multiple polysulfide species participate in the various charge transfer reactions. The chemistry ... 詳細を見る

In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... 詳細を見る

Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... 詳細を見る

リチウムイオン電池の負極グラファイト電極上の銅コレクターは, 過放電時に溶解することが確認されています. 溶解により集電体が不可逆的に損傷し, 溶解した銅イオンが再析出してデンドライトを形成する可能性があるため, 安全上の懸念事項となります. 電池は通常, 過放電を回避するために, セルレベルまたはパックレベルのいずれかで指定された電圧制限内で動作します. しかし, パック内では個々のセル間の電荷不均衡により, あるいはこのチュートリアルで部分的に調査するように, 単一の電池セル内の電極の局所的な不均一性により, 過放電が発生する可能性があります. ... 詳細を見る
