Novel Ag@Nitrogen-doped Porous Carbon Composite with High Electrochemical Performance as Anode Materials for Lithium-ion Batteries

摘要

A novel Ag@nitrogen-doped porous carbon（Ag-NPC） composite was synthesized via a facile hydrothermal method and applied as an anode material in lithium-ion batteries（LIBs）. Using this method, Ag nanoparticles（Ag NPs） were embedded in NPC through thermal decomposition of Ag NO3 in the pores of NPC. The reversible capacity of Ag-NPC remained at 852 m Ah g-1after 200 cycles at a current density of 0.1 A g-1, showing its remarkable cycling stability. The enhancement of the electrochemical properties such as cycling performance,reversible capacity and rate performance of Ag-NPC compared to the NPC contributed to the synergistic effects between Ag NPs and NPC.
