MnO/MWCNT Composite Anode Material with Low Temperature Calcination Process for High Performance Lithium-Ion Batteries

Abstract

MnO/MWCNT composites were synthesized through a vacuum solution infiltration method and a subsequent low temperature calcination process. The MnO/MWCNT composites with an empty space among the nanoparticles or inside the Multiwalled carbon nanotubes (MWCNTs), which can act as a buffer matrix to release the volume expansion, effectively solved the existing issues of active nanoparticle dissolution and aggregation during the lithium ion insertion/extraction. The MWCNTs in the composites can also improve the conductivity of electrode. Electrochemical tests show that the composites exhibit excellent cycling property and good rate performance.
