Abstract

Herein, partially reduced graphite oxide (PRGO) was prepared by the thermal reduction of GO at 220 °C and investigated as a cathode material for lithium-ion batteries. After an initial galvanostatic charging process to 5.2 V, the PRGO shows a high capacity of 230 mA h g−1, and the capacity retention can reach approximately 90% even after 8000 cycles at 1 A g−1. XPS, Raman spectroscopy, FTIR spectroscopy and TEM analysis showed that the active oxygen functional groups obviously increased after electrochemical activation; this was considered the reason for the increase in capacity. In this study, we demonstrated a novel strategy for the preparation of high-performance organic cathode materials for lithium-ion batteries.
