Aerosol deposition technology and its applications in batteries

Abstract

Aerosol deposition (AD) method is a kind of additive manufacturing technology for fabricating dense films such as metals and ceramics at room temperature. It resolves the challenge of integrating ceramic films onto temperature-sensitive substrates, including metals, glasses, and polymers. It should be emphasized that the AD is a spray coating technology that uses powder without thermal assistance to generate films with high density. Compared to the traditional sputter-based approach, the AD shows several advantages in efficiency, convenience, better interfacial bonding and so on. Therefore, it opens some possibilities to the field of batteries, especially all-solid-state batteries (ASSBs) and draws much attention not only for research but also for large scale applications.The purpose of this work is to provide a critical review on the science and technology of AD as well as its applications in the field of batteries. The process, mechanism and effective parameters of AD, and recent developments in AD applications in the field of batteries will be systematically reviewed so that a trend for AD will be finally provided.
