Lithium metal battery has been considered as one of the potential candidates for next‐
generation energy storage systems. However, the dendrite growth issue in Li anodes results
in low practical energy density, short lifespan, and poor safety performance. The strategies
in suppressing Li dendrite growth are mostly conducted in materials‐level coin cells, while
their validity in device‐level pouch cells is still under debate. It is imperative to address
dendrite issues in pouch cells to realize the practical application of Li metal batteries. This …

Li metal batteries are considered to be important candidates for use in next-generation
systems, including electric vertical take-off and landing, and even electric airplanes. In article
number 2202518, Xin-Bing Cheng, Jingfa Li, Qiang Zhang, and co-workers present a
comprehensive overview of the failure mechanism and regulation strategies of Li metal
anodes in practical pouch cells. Dendrite growth is among the toughest issues in the pouch
cell, which is one of the practical forms for the commercial applications of Li metal batteries.
