Abstract
En 中文
The growing demand for compact, and reliable energy storage is driving innovation across electric vehicles, grid systems, and miniaturized electronics. The continued miniaturization of devices requires ultrathin and highly reliable energy storage capable of autonomous operation in rigid, flexible, and cryogenic platforms. Thin-film solid-state batteries (TFSSBs) are emerging as a key solution, with thin-film solid electrolytes (SEs) enabling precise control over ionic transport, interfacial stability, and mechanical resilience at reduced dimensions. Fabrication techniques such as pulsed laser deposition (PLD), physical vapor deposition, atomic layer deposition (ALD), and solution-based methods allow nanoscale tuning of electrolyte composition and structure, enhancing ionic conductivity and electrochemical performance. This article highlights the critical role of TFSEs in advancing solid-state batteries (SSBs), emphasizing PLD for its exceptional precision and tunability. By linking deposition parameters to ionic transport and interface dynamics through operando X-ray diffraction, Raman spectroscopy, and time-of-flight secondary ion mass spectrometry, this spotlight article also outlines fabrication principles and research pathways to accelerate the translation of TFSSBs from laboratory prototypes to practical, scalable devices.
