Cover Feature: Fe‐Based Mesoporous Nanostructures for Electrochemical Conversion and Storage of Energy (Batteries & Supercaps 3/2021)

Abstract

The Cover Feature illustrates a Fe‐based mesoporous nanostructure (located at the center) and its applications in electrochemical energy conversion (water splitting) and various electrochemical energy storage devices (Li‐ion batteries and supercapacitors). More information can be found in the Review by J. Lee and co‐workers.

Preparation of Nitrogen‐Doped Graphene with Hollow Nano‐Hemispheres from FexOy@Fe‐N‐GN: Towards High Capacity and Durable Anode for Li‐Ion Batteries by Chemical Modifications

“…Although the gravimetric capacity obtained for N-GN and Fe x O y @Fe-N-GN are in the average given in the literature, the value obtained for Fe-N-GN is one of the highest among carbon-based materials. [13,[37][38][39] At this point, the long-term charge-discharge performance at 0.5 A g À 1 , which has a relatively high current density, can provide significant information in terms of their real-life applicability. Charge-discharge performances of 250 cycles recorded during impedance measurements of the samples are given in Figure 7b.…”
