Materials & Design, Volume 247, November 2024, Article number 1134460264-1275https://doi.org/10.1016/j.matdes.2024.113446https://dspace.lib.cranfield.ac.uk/handle/1826/23294Developing Electrophoretic Deposition (EPD) for Composite Structural Batteries (CSBs) could revolutionise energy storage technology. CSBs offer an innovative solution by seamlessly integrating batteries into structures and effectively reducing weight and space constraints. Despite its successful implementation across various fields, EPD method still lacks comprehensive understanding of the underlying physical and chemical processes due to the number of variables involved. In this study the effects of key parameters associated with the process are investigated with a coupled FEM and analytical approach to find correlations with the deposition process. A Taguchi Design of Experiment with five parameters, namely voltage, concentration, relative weight ratio of LiFePO4 – carbon black particles, length and perimeter of the electrodes is implemented to identify the correlations with mass deposited, thickness of the coating and yield rate when LiFePO4 and Carbon Black particles in ethanol suspension are used. In order to capture the variation over time, each parameter is studied at six different time of deposition. A concentration that optimises yield rate resulting in thickness and mass deposition is identified. The resistivity of the suspension dictates the yield rate dynamics, allowing it to be designed within a specific range to meet requirements of different applications.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Structural BatteryElectrophoretic DepositionLiFePO 4 coatingNumerical modelStructural Cathode40 Engineering4016 Materials Engineering4017 Mechanical Engineering7 Affordable and Clean EnergyMaterials4016 Materials engineering4017 Mechanical engineeringArticle1873-4197558561113446247
