Abstract: Nanostructured thin films represent a promising pathway for next-generation high-performance batteries due to their enhanced ion transport, large surface area, and improved electrochemical stability. This review summarises key advances reported between 2019 and 2025 in thin-film materials used for battery electrodes, electrolytes, and separators. Emphasis is placed on advanced fabrication techniques, including atomic layer deposition and sol-gel synthesis, together with modern characterisation methods. The influence of nanostructured morphology on electrochemical performance is critically examined, particularly in terms of charge-discharge efficiency, interface stability, and cycling durability. In addition, hybrid and multilayer architectures, such as composite and interface-engineered systems, are discussed for their ability to improve conductivity and energy density. Major challenges related to large-scale manufacturing, cost, and long-term structural integrity are identified, and potential mitigation strategies are outlined. Overall, the review highlights how integrating materials science, nanoengineering, and AI-driven design can accelerate the commercialisation of nanostructured thin-film battery technologies.

Keywords: nanostructured thin films; high-capacity; battery technologies; electrochemical processes; polyanionic compound.
