摘要：
Herein, a facile hydrothermal method is utilized to prepare a (NH4)(2)V7O16/reduced graphene oxide (rGO) composite. In an aqueous electrolyte, the obtained (NH4)(2)V7O16/rGO exhibits superior lithium storage characteristics compared to pure (NH4)(2)V7O16 in both the three-electrode configuration and full cell. This improvement can be ascribed to the synergistic effects of incorporation of defective oxygen and rGO modification. The present study proposes a feasible strategy for enhancing the electrochemical properties of (NH4)(2)V7O16 and demonstrates the potential of the (NH4)(2)V7O16/rGO composite for aqueous rechargeable lithium-ion batteries.
