Metallic Fe nanoparticles trapped in self-adapting nanoreactors: a novel high-capacity anode for aqueous Ni–Fe batteries†
Abstract
Metallic Fe nanoparticles trapped in thick carbon nanoreactors are realized in situ via conventional gas-phase reactions. These derived nanohybrids exhibit unique self-adapting properties, with prominent anodic performance in terms of both stored capacity and cyclic durability when serving as anodes for Ni–Fe batteries.
