Fe-based metallopolymer nanowall-based composites for Li-O2 battery cathode
Metallopolymer nanowalls were prepared through a simple wet-chemical process using reduced graphene oxides as heterogeneous nucleation aids, which also help to form conductive electron paths. The nanowalls grow vertically ...
Integrated charge transfer in colloidal Cu-MnO heterostructures for high-performance lithium-ion batteries
Nanodimensional monodispersed Cu–MnO heterostructures were synthesized via a facile solution-based method. Cu–MnO heterostructures with narrow size distribution were successfully achieved in the presence of organic surfactants ...
Vanadium pentoxide-based cathode materials for lithium-ion batteries : morphology control, carbon hybridization, and cation doping
Vanadium pentoxide (V2O5) is a promising cathode material for high-performance lithium-ion batteries (LIBs) because of its high specific capacity, low cost, and abundant source. However, the practical application of V2O5 ...
Fabrication of flexible thermoelectric thin film devices by inkjet printing
Ink-jet printing of thermoelectric nanomaterials is successfully used to fabricate flexible thin film TE devices for power generation and cooling.
Carbon nanotube-encapsulated noble metal nanoparticle hybrid as a cathode material for Li-oxygen batteries
Although Li-oxygen batteries offer extremely high theoretical specific energy, their practical application still faces critical challenges. One of the main obstacles is the high charge overpotential caused by sluggish ...
n-type carbon nanotubes/silver telluride nanohybrid buckypaper with a high-thermoelectric figure of merit
N-type thermoelectric materials was made from CNT buckypapers. We used Ag2Te to achieve electron injection to the CNTs. The thermoelectric characterizations on more than 50 samples show that the CNTs/Ag2Te hybrids exhibit ...
Aqueous-based chemical route toward ambient preparation of multicomponent core-shell nanotubes
Room-temperature synthesized V2O5@MnO2 core–shell nanotubes with tunable tunnel dimensions via a facile aqueous-based method are presented. The rational-designed tubular morphology endows them with good permeability of ...
Compressed hydrogen gas-induced synthesis of Au–Pt core–shell nanoparticle chains towards high-performance catalysts for Li–O 2 batteries
Herein we reported a green synthetic route for the preparation of Au–Pt core–shell nanoparticle chains in a two-step route without the use of any surfactants. In the synthesis, compressed hydrogen was used as a reducing ...
