Abstract
Owing to the high electrochemical reactivity and infinite volume expansion of lithium metal anode, the uncontrollable lithium dendrite growth drags the lithium metal anode out of the real application for a long time. Herein, a heterogeneous seed layer of Au nanoparticles (NPs) is uniformly deposited on the 3D porous vertical graphene nanosheets on carbon cloth (Au-VG/CC) to construct a lithiophilic surface, achieving a smooth and dendrite-free morphology. As a result, Au-VG/CC electrode delivers a small voltage hysteresis of 67.2 mV and a long cycling life of more than 500 h at a high current density of 5 mA cm−2 with 5 mAh cm−2. Results of XRD and in-situ transmission electron microscopy indicate that the formed lithiophilic layer is Li3Au which can guide the lithium deposition. Moreover, a full battery assembled with [email protected]/CC as the anode and LiFePO4 as the cathode delivers 77.3 mAh g−1 at 100 mA g−1 after 200 cycles.
