Abstract: All-solid-state thin film lithium batteries, having perfect electrode/electrolyte solid/solid interface, can effectively improve the safety issue of the current commercial lithium-ion batteries using liquid electrolyte. Their outstanding electrochemical properties, including ultralong cycle life, wide temperature range, and low self-discharge, are superior to those of the bulk solid-state batteries and attract a lot of interest. The high fabrication cost and low energy density per unit area are the two main drawbacks for the current thin film battery technology, which limit their broad applications. In this perspective, we summarize the working principle, key materials, and research progress for thin film lithium batteries. The current commercialization and development bottleneck of solid-state thin film lithium batteries are summarized, and perspectives on future development and application of the next-generation thin film lithium batteries are provided.

Key words: all-solid-state lithium batteries, thin film lithium batteries, solid electrolyte, thin film deposition
