与当前用于熔炼铝的Hall-Heroult工艺相比，基于固体氧化物膜（SOM）的电解工艺带来各种优点，诸如简化设计、降低成本、降低能耗以及许多其他环境效益。然而，最先进的SOM电解过程受到固体氧化物膜的稳定性及其与熔融盐和电极材料的相容性的限制。这项工作将确定具有成本效益的熔盐组合物和膜材料/结构沿着与电极和集电器，都是化学相容的，并提供最佳的电化学性能，有效的氧化铝电解。
Compared with the current Hall–Heroult process for smelting aluminum, the Solid Oxide Membrane (SOM)-Based electrolysis process brings various advantages such as simplified design, lower cost, lower energy use, and many other environmental benefits. However, the state-of-the-art SOM electrolysis process is limited by the solid oxide membrane’s stability and its compatibility with the molten salt and the electrode materials. This work will identify cost-effective molten salt compositions and membrane materials/architecture along with electrodes and current collectors that are all chemically compatible and provide optimum electrochemical properties for efficient aluminum oxide electrolysis.
