Review on nanomaterials for next‐generation batteries with lithium metal anodes

Abstract

AbstractStable lithium (Li) metal anode is highly pursued to accelerate the development of high‐energy‐density battery systems. In this article, the stable Li metal batteries boosted by nano‐technology and nano‐materials are comprehensively reviewed. Two emerging strategies, including nanostructured lithium metal frameworks and nano‐artificial solid‐electrolyte interphase (SEI) are particularly focused. First, typical conductive/non‐conductive nanostructured frameworks and the corresponding merits are introduced. The physical and chemical modifications of the traditional nano‐frameworks are further summarized. In addition, the nano‐artificial SEIs built by in situ regulation and ex situ fabrication strategies are involved, with the scientific and technologic issues concerned on the interface well discussed. This review mainly focuses on the fresh benefits brought by nano‐technology and nano‐materials on building better lithium metal batteries. The recent advances of nanostructured lithium metal frameworks and nanoscale artificial SEIs are concluded, and the challenges as well as promising directions for future research are prospected.
