Ultrafast Laser Texturing of Ceramic Electrolytes toward Solid-State Battery Application
Source abstract
Abstract
Solid-state batteries are expected to complement liquid-based lithium-ion batteries (LIBs) with improved safety and energy density. However, point-to-point interface contact between oxide-based ceramic solid-state electrolytes (SSEs) and electrodes impedes Li-ion transfer and degrades the battery performance. Herein, micropatterns with controllable geometries were created onto perovskite-type SSE surfaces via femtosecond ultrafast laser processing. Laser-textured SSEs with two-directional (2D) perpendicular grooves can achieve a significant reduction in interfacial resistance (<1 versus 3416.81 Ω cm –2 for bare sample) attributed to increased contact area and trapping of the liquid electrolyte. This work serves as a proof-of-concept for applying ultrafast laser processing toward solid-state battery applications.
