电泳沉积（EPD）是一种非常方便和示范的工业操作，用于制造表面涂层。近年来，越来越多的证据表明，这种技术可以用于生产储能电极（特别是锂离子电池、固态器件、超级电容器和液流电池），但它们在工业化方面的进展仍不明朗。本研究以活性炭（AC）作为超级电容器材料的示例性，报告了EPD技术生产的多孔储能电极的实用方面。展示了具有商业可行参数的实用电极，特别是高密度活性材料（超过9.8 mg cm−2）和非常厚的涂层（约168 μm）。研究包括胶体电解质配方，电极沉积参数和电池性能测试报告。通过各种表征工具研究了材料和电极的性能。原型A7大小的袋状电池组装和测试，以显示在商业电池格式的实用EPD电极的证据。介绍了EPD在料浆铸造上的电化学性能。简而言之，这项研究表明了用于电化学储能的实用EPD电极的成功生产，这与扩大工业应用直接相关，并且可以作为任何电池和超级电容器材料的平台电极制造技术。电泳沉积（EPD）是一种非常方便和示范的工业操作涂料制造。它现在适用于生产用于电池，电容器和固态器件的实用储能电极。
Electrophoretic deposition (EPD) is a highly convenient and demonstrated industrial operation for the manufacture of surface coatings. Recent years are seeing increasing evidence in using this technique to produce energy storage electrodes (notably for lithium-ion batteries, solid-state devices, supercapacitors, and flow batteries), but their advancement for industrialisation remains unclear. Using activated carbon (AC) as an exemplary supercapacitor material, this study reports the practical aspects of porous energy storage electrodes produced by the EPD technique. Practical electrodes with commercially viable parameters are shown, specifically high density active material (in excess of 9.8 mg cm−2) and very thick coating layer (about 168 μm). Research investigations including colloidal electrolyte formulations, electrode deposition parameters and cell performance testing are reported. Materials and electrode properties were studied by various charactersisation tools. Prototype A7 sized pouch cells were assembled and tested to show evidence of practical EPD electrodes in a commercial cell format. Electrochemical performance of EPD over slurry casting is presented. In short, this research shows the successful production of practical EPD electrodes for electrochemical energy storage, which is directly relevant for scale-up industrial adoption and can be applied as a platform electrode manufacturing technology for any battery and supercapacitor materials. Electrophoretic deposition (EPD) is a highly convenient and demonstrated industrial operation for coatings manufacture. It is now suitable for the production of practical energy storage electrodes for batteries, capacitors & solid-state devices.
