Abstract
Herein, a method of synthesizing Co2SiO4 at a low temperature of 900 °C is reported. By synthesizing the precursor with a facile hydrothermal method and post-annealing in air at 900 °C, Co2SiO4 with good purity was obtained. The Co2SiO4 nanoparticles were characterized by XRD, XPS and TEM to analyze their structure and morphology. To evaluate their performance as the anode material for a lithium ion battery, the Co2SiO4-based electrodes were investigated by cyclic voltammetry (CV), galvanostatic cycling and a rate test. Such electrodes display superior electrochemical performance, such as providing a large reversible capacity as high as 650 mA h g−1 at a current density of 100 mA g−1 after 100 cycles, demonstrating excellent cyclic performance and good rate capacity.This publication has 38 references indexed in Scilit:
