This process aims to improve the homogeneity and electrochemical performance of a solid-state cathode composite consisting of LiFePO4 (LFP), Li3InCl6 (LIC) and carbon black (CB). A downwards directed microjet was employed to enhance fluidization and mixing quality. The research involved a parametric study, examining various vibration intensities, microjet nozzle sizes, and fluidization times to determine the optimal conditions for achieving a homogeneous composite on the microscale. Scanning electron microscope (SEM) and focused ion beam SEM (FIB-SEM) imaging were used to assess the mixing quality and confirm the formation of heteroagglomerates. Assisted fluidization alone produces composites with inferior mixing quality, whereas a microjet significantly improves mixing. Electrochemical testing reveals that a vibrated fluidized bed alone is inadequate for mixing submicron-sized particles for battery applications, whereas the microjet enables the mixing and ionically bound active material.en0032-59102025Elsevierhttps://creativecommons.org/licenses/by/4.0/Heteroagglomerates | Microjet Assistance | Nanoparticle Mixing | Solid-state battery (ASSB) | Vibrated Fluidized BedTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringNatural Sciences and Mathematics::541: Physical; TheoreticalJournal Articlehttps://doi.org/10.15480/882.1503710.1016/j.powtec.2025.12090610.15480/882.15037Journal Article
