Ultrafast rechargeable Li-ion batteries are most urgently needed for personal electronics and commercial application since they could fuel various energy applications. These days, much time and efforts have been paid on the research of ultrafast rechargeable Li-ion batteries, however, less breakthrough was appeared. In this manuscript, the CuCr2O4@RGO, a new-type of nanocomposite material, demonstrates a promising future application when it was used as an anode material of the Li-ion batteries. The Li-ion batteries displays a specific capacity of about 410 mAh g(-1) and a coulombic efficiency of approximately 98 % at the discharge/charge current rate of 1000 mA g(-1). We also found that the batteries constructed by CuCr2O4@RGO nanocomposites as active anode materials can be fully charged within 5 min, with a current density of 4000 mA g(-1) and strive against more than 900 cycles without capacity decay. All the results indicate that the CuCr2O4@RGO nanocomposites with spinel structure of the mixed transitional metal oxide are promising for the anode materials of ultrafast rechargeable Li-ion batteries.
