Polyethylene oxide film coating enhances lithium cycling efficiency of an anode-free lithium-metal battery
TL;DR: This work revealed the homogeneous deposition of lithium and effective suppression of dendrite formation using a copper electrode coated with a polyethylene oxide (PEO) film in an electrolyte comprising 1 M LiTFSI, DME/DOL (1/1, v/v) and 2 wt% LiNO3.

TL;DR: In this article, the authors visualized lithium dendrite growth dynamics on the Cu surface by in operando transmission X-ray microscopy (TXM) and found that the aspect ratio (height/width) of deposited lithium has increased with charge passed during plating, indicating a faster growing from the base.
