Energy Engineer with a multidisciplinary background and experience in Materials Science on the synthesis and characterization of oxides. Graduated with a Bachelor of Science and Technology and Energy Engineer by the Universidade Federal do ABC (UFABC, Brazil). PhD in Materials Science on Solid-State Lithium Batteries at the University of Twente (UT, Netherlands). Currently, a Researcher in the Inorganic Materials Science group (UT, Netherlands), carrying out studies in the fields of Solid-state batteries (SSB), Pulsed Laser Deposition (PLD), and advanced techniques in Scanning Probe Microscopy (SPM).
Lithium-ion batteries are the primary power source for many applications, but none of the current devices can fully satisfy all the projected energy storage needs. Common rechargeable batteries are based on liquid electrolytes, which limit their design and safety. Therefore, the need for all-solid-state micro-batteries arises, showing enhanced safety, volumetric energy/power density and chemical stability. Planar 2D solid-state thin-film batteries exhibit undesirable energy vs power balance, which can be improved by applying 3D geometries, increasing the internal surface area.
Vertically aligned nanocomposite (VAN) thin films have been developed as a new materials’ platform for creating self-assembled device architectures and multi functionalities. They show a wide range of attributes arising from the strong interplay among the materials’ properties. Epitaxial VANs are self-assembled through pulsed laser deposition (PLD), without control of the deposition sequence, required for planar multilayer films. Although various epitaxial VANs have been studied in the last decade, lithium-based VANs have yet to be fully explored.
Even though lithium-based self-assembled VANs have been demonstrated1, further aspects of these complex structures need to be investigated.
