Interface engineering of inorganic solid-state lithium batteries via atomic and molecular layer deposition

Abstract

Currently, conventional organic liquid electrolytes (OLEs) are the main limiting factor for the next generation of high-energy lithium batteries. There is growing interest in inorganic solid-state electrolytes (ISEs). However, ISEs still face various challenges in practical applications, particularly at the interface between ISE and the electrode, which significantly affects the performance of solid-state batteries (SSBs). In recent decades, atomic and molecular layer deposition (ALD and MLD) techniques, widely used to manipulate interface properties and construct novel electrode structures, have emerged as promising strategies to address the interface challenges faced by ISEs. This review focuses on the latest developments and applications of ALD/MLD technology in SSBs, including interface modification of cathodes and lithium metal anodes. From the perspective of interface strategy mechanism, we present experimental progress and computational simulations related to interface chemistry and electrochemical stability in thermodynamic contents. In addition, this article explores the future direction and prospects for ALD/MLD in dynamic stability engineering of interfaces SSBs. (Figure presented.).
