WebA novel mosaic TiNb2O7/TiNbN2 anode is developed for a “structural function motif” with accelerated low-temperature dynamics. The phase-junction interface enables reduced diffusion barrier, enhanced electrical conductivity, and promoted Li+-de-solvation ability, which leads to superior rate performance and high durability at low-temperature conditions. Web10 dec. 2024 · Lithium metal is the ideal anode material for high-energy-density lithium-based batteries. Nevertheless, lithium metal tends to accumulate on the surface of the … 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.
