Three-Dimensional Porous Graphene-Metal Oxide Composite Microspheres: Preparation and Application in Li-Ion Batteries

One-pot synthesis of manganese oxide-carbon composite microspheres with three dimensional channels for Li-ion batteries

The fabrication of manganese oxide-carbon composite microspheres with open nanochannels and their electrochemical performance as anode materials for lithium ion batteries are investigated. Amorphous-like Mn3O4 nanoparticles embedded in a carbon matrix with three-dimensional channels are fabricated by one-pot spray pyrolysis. The electrochemical properties of the Mn3O4 nanopowders are also compa...

Hierarchically porous and nitrogen, sulfur-codoped graphene-like microspheres as a high capacity anode for lithium ion batteries.

Novel hierarchically porous and nitrogen, sulfur-codoped graphene-like microspheres (3D NS-GSs) are synthesized using Ni microspheres as the template and using poly(vinylpyrrolidone) and (NH4)2S2O8 as the carbon and nitrogen precursor, respectively. As an anode material in lithium ion batteries, the 3D NS-GS electrode displays a superior capacity with excellent cycling stability.

High quality graphitized graphene as an anode material for lithium ion batteries.

High quality graphitized graphene has been successfully synthesized by solid-exfoliation of graphite and a subsequent wet chemical process. The as-obtained graphene exhibits charge-discharge behaviour quite different from that of reduced graphene oxide and shows enhanced cycling and rate performance compared with commercial mesocarbon microbeads (MCMBs) for lithium ion batteries.

Unique Cobalt Sulfide/Reduced Graphene Oxide Composite as an Anode for Sodium-Ion Batteries with Superior Rate Capability and Long Cycling Stability.

Exploitation of high-performance anode materials is essential but challenging to the development of sodium-ion batteries (SIBs). Among all proposed anode materials for SIBs, sulfides have been proved promising candidates due to their unique chemical and physical properties. In this work, a facile solvothermal method to in situ decorate cobalt sulfide (CoS) nanoplates on reduced graphene oxide (...
