Zn Batteries: Dendrite‐Free Flexible Fiber‐Shaped Zn Battery with Long Cycle Life in Water and Air (Adv. Energy Mater. 41/2019)

In article number 1901434, Jianli Cheng, Bin Wang, Jun Lu, and co-workers report that the strong adsorption of zinc on N,O-functionalized surficial sites of carbon fibers facilitates a Zn2+ uniform distribution and abates dendrite growth. The fabricated fiber-shaped Zn/Co3O4 battery shows long cycle life in water and air, impressive flexibility, and high energy density.
