Pulsed Current Constructs 3DM Cu/ZnO Current Collector Composite Anode for Free-Dendritic Lithium Metal Batteries

Although lithium metal is an ideal anode material for achieving high-energy-density lithium-based batteries, the uneven deposition/exfoliation process of during cycling easily triggers formation dendrites and dead lithium, which leads to a low Coulombic efficiency safety issues. In this paper, lithiophilic 3D copper mesh current collector designed by using ZnO pulsed plating applied battery composite anode. Under action field, novel achieved homogeneous deposition ions. The lithium-to-copper half cells assembled with 3DM Cu/ZnO from presented as high 97.8% after 1 min activation at 3 mA cm−2 follow 10 cycles stripping 0.5 cm−2. Moreover, symmetric cell could be stable 1500 h limited capacity mAh cm−2, full (LiFePO4 cathode) maintained about 90% 30th cycle C. This mechanism advanced strategy improve cyclic stability crucial designing batteries.
