Lithium-ion batteries (LiBs) performance is heavily influenced by their electrodes' properties, which dictate charge transport, energy storage, and overall efficiency. This study explores dry spray deposition as a solvent-free method for applying MXene coatings to additively manufactured LiB electrodes. By eliminating binders and solvents and structural optimization through additive manufacturing (AM), this approach aims to create a uniform, conductive layer while preserving electrode porosity and reducing processing time. At the submicron to micron scale, van der Waals forces strongly affect particle mixing, impacting the uniformity and deposition quality of MXene coatings. Electrochemical performance is assessed using open circuit voltage (OCV), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) to evaluate charge storage and interfacial resistance. By integrating structural optimization through AM with experimental validation, this study advances the understanding of dry powder mixing and highlights MXene coatings' potential for improving LiB electrodes through scalable, solvent-free manufacturing.
