WebThe lithiophilic NiO nanoarrays decrease Li nucleation barrier and local current density, and provide abundant sites for nucleation. The Ni skeleton with vertical channels and interconnected small pores, not only provides Li storage space and ion channels, but also alleviates top-surface deposition and improved uniformity of Li distribution. Figure 2 illustrates the synthesis and morphology of Li-metal anodes with various upper interfacial layers. CNT, ZnO/CNT, graphene, carbon black, or carbon fiber were used as the starting materials. We first dry these materials in vacuum at 120 °C for 2 h, move them into an Ar-filled glove box, disperse them in 1,3 … Meer weergeven The SEM images (Fig. 4 and Supplementary Figs. 3–8) reveal the top-view morphology of the interfacial-layer-coated Li foils after extended stripping/plating … Meer weergeven Even the best interfacial layer, i.e., the lithiophobic CNT-coated Li foil, still suffered from voltage divergence after 200 cycles at 5 … Meer weergeven Electrochemical performance of cells assembled by Li foils with normal CNT and GZCNT interfacial layers are compared with bare Li foils in Fig. 6. The symmetrical cell of bare Li … Meer weergeven WebIn particular, the utilization of lithiophilic materials, which allows for the effective control of nucleation sites to stabilize Li deposition, has emerged as an essential strategy … grain of a steak
