“…This indicates that the specially designed 3DP-NGA microlattice has a small charge transfer resistance during cycling. 61,65 The diffusion coefficient ( D ) can be obtained from the relationship between Z w and ω −1/2 by the following formula: 66 where R is universal gas constant, T is the absolute temperature, A is the value of electrode surface area, n is the number of electrons required for a molecule to be oxidized, F is Faraday constant, C is the concentration of sodium ions in the electrolyte, and σ is the slope of the curve plotted with Z w as the abscissa and ω −1/2 as the ordinate. The diffusion coefficient D of the 3DP-NGA electrode is 5.33 × 10 −14 cm 2 s −1 , which is higher than that of the 3DP-rGA electrode (1.06 × 10 −15 cm 2 s −1 ), indicating a faster kinetics enabled by the 3DP-NGA electrode (Fig.…”

Building Fast Ion-Conducting Pathways on 3D Metallic Scaffolds for High-Performance Sodium Metal Anodes

“…It can be obviously seen that the Na + concentration drastically decreases at the NiF 2 surface, indicating the efficient guidance of the NaF-enriched SEI layer for rapid migration and uniform distribution of the Na + flux. Meanwhile, the current density is uniformly distributed on the NiF 2 @NF surface, whereas “hot spots” are observed on the surface of pure NF and NiO@NF scaffolds, which leads to the rampant Na dendrite formation. , …”

“…Meanwhile, the current density is uniformly distributed on the NiF 2 @NF surface, whereas "hot spots" are observed on the surface of pure NF and NiO@NF scaffolds, which leads to the rampant Na dendrite formation. 28,29 Fluoroethylene carbonate (FEC) has been extensively employed as an electrolyte additive in Li/Na-ion batteries. The decomposition of FEC provides a NaF-containing SEI, leading to enhanced cycling stability with high CE.…”
