1つの電池モジュールごとに未来をシミュレート
STAR-CCM+ はリチウムイオン電極物質の特性と挙動を理解する上で役立つシミュレーションツールを提供しています。電極の活物質 (特にカソード活物質) は通常リチウムイオン電池セルで最も高価な部品であるため、その特性と挙動を理解することはセル製造メーカーにとって非常に重要です。
  • Temperature distribution analysis of an ASCS battery module of 84 cells: 42 cells are connected in series, and each row is connected in parallel. The liquid-cooled plates are lateraly postionned on each side of those rows (Model courtesy of ASCS, Stuttgart and Behr).
  • CD-adapco tools are used by a number of fuel cell companies to understand and optimize both proton exchange membrane (PEM) and solid oxide (SOFC) fuel cells. The image shows a single cell SOFC that incorporates heat transfer, electrochemical reaction, and multi-component gas transport.
  • Automotive companies utilize electroplating to make plastic parts look like metal. In the above image, Chromium III plating thickness on a plastic automotive grille is predicted using secondary current distributions. Chromium plating is the final layer in a multistep electroplating process consisting of pretreatment, copper, nickel, and finally chrome deposition. Choosing locations to make electric contact with the plastic part is crucial in obtaining...
  • Liquid electrolytes (i.e. acids and bases) can be used to pattern metal and semiconductor surfaces. The removal process is an electrochemical surface reaction that is often dependent on reactant and product concentrations, therefore non-homogenous etch rates are common. STAR-CCM+ can be used to aid understanding and optimization of wet-etch processes by predicting these concentration dependent etch rates. The above images show etch-product concentration...
  • Research at MIT has shown that ionic wind can produce 55 times more thrust per kilowatt than traditional jet engines http://newsoffice.mit.edu/2013/ionic-thrusters-0403 . This type of airflow can be produced by applying a voltage between two electrodes. If one electrode is sharp enough (like a wire or blade), a corona discharge occurs near the electrode surface that ionizes certain gas species (often O 2 + in air). These charged ions migrate from one...

電極の微細構造をモデリングしてその電気化学反応を予測する機能は、セル設計の品質とパフォーマンスを判定する上で役立ちます。例えば多孔電極をどの程度蛇行させることができるかを判定したり、粒子のサイズと分布を解析したりパラメータ化を行うことができます。これはどちらも電極に関して重要な要素となります。
