Silver Nanowires@Mn3O4 Core–Shell Nanocables as Advanced Electrode Materials for Aqueous Asymmetric Supercapacitors

Abstract High‐electrical‐conductivity silver nanowire (AgNW)@Mn 3 O 4 nanocables are prepared by facile chemical precipitation and subsequent thermal treatment; these treatments are environmentally friendly, low cost, and easy for mass production. The obtained Mn 3 O 4 nanoparticles (20–30 nm) possess many interparticle mesoporous structures. The AgNW‐supported Mn 3 O 4 nanoparticles allow for a large exposed electroactive area, rapid ion and …
