With the development of wearable electronics, sustainable energy-charged fiber-shaped aqueous rechargeable batteries have become attractive power sources. Environmentally benign zinc-silver oxide (Zn–Ag2O) batteries with high energy density and ultra-stable output voltage have been demonstrated to be promising energy-storage devices. However, the major bottleneck for extensive application of Zn–Ag2O batteries is poor cyclic performance and low energy density due to structural pulverization, migration of Ag ions, and low loading of active substances. Herein, a quasi-solid-state fiber-shaped Zn–Ag2O battery was constructed employing Ag2O on a metal–organic framework (MOF)-derived N-doped carbon nanosheet array (NC) with a poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (PEDOT:PSS) buffer layer as the cathode. A PEDOT:PSS protective layer could suppress structural pulverization …
