摘　　要：为了提高锂空气电池性能,有效缓解体积膨胀和负极粉化的现象,实验采用金属镍网原位生长氧化镍薄片并与金属锂复合构建复合锂负极Li@Ni-NiO,将其应用于锂空气电池。Li@Ni-NiO的版电池能够在180个循环内维持98%的库伦效率,基于Li@Ni-NiO的锂空气电池可以稳定循环120圈。复合负极有效地缓解了枝晶生长,改善了电场分布,最终达到均匀电镀的目的,为高性能锂空气电池的负极发展提供了一种新的思路。In order to improve the performance of lithium-air(Li-air)batteries,effectively alleviate the phenomenon of volume expansion and anode pulverization,a composite lithium anode Li@Ni-NiO was synthesized by in-situ grow of nickel oxide flakes on nickel mesh and composited with metal Li for Li-air batteries.The Li@Ni-NiO-based version of the battery can maintain coulombic efficiency of 98%for 180 cycles,and the Li@Ni-NiO-based Li-air battery can cycle stably for 120 cycles.The composite anode effectively relieves the dendrite growth,improves the electric field distribution,and finally achieves the purpose of uniform electroplating,which provides a new idea for the development of anodes for high-performance Li-air batteries.
