Abstract The CK bond plays a significant role in stabilizing the Na‐K (NaK) alloy electrodes due to enhancive interfacial affinity. In this study, method for constructing semi‐solid K metal with rich bonds by situ replacement of N‐doped carbon nanotubes (CNT) and liquid NaK is proposed. Based on infrared thermal imaging technique combined heat calculation, X‐ray photoelectron spectroscopy elemental analysis, reaction thermodynamic graphite‐N, which widely distributed wall CNT, offers plenty...
Abstract Separators with low‐cost, superior mechanical properties, such as nanofiber materials, are considered a viable option for solving the dendritic problem in alkali metal batteries. Consuming dendrites rather than blocking them underpins long‐life stable cycle performance of cell. Herein, five‐layer structural separator (LiNO 3 @PVDF@mask) is presented, which mask used framework and polyvinylidene fluoride (PVDF) layer loaded LiNO can generate passivation by reacting K dendrites. In...
Abstract Sodium–potassium (NaK) alloy electrodes are ideal for next‐generation dendrite‐free alkali metal due to their nature. However, issues such as slow diffusion kinetics the large K + radius and loss of active potassium during reaction severely limit its application. Here a novel cobalt/nitrogen‐doped carbon material is designed it applied construction NaK electrode. The experimental theoretical results indicate that confining effect nitrogen‐doped graphitic layer can protect cobalt...
Sodium-potassium (NaK) alloys in a specific ratio can maintain their liquid state at room temperature, rendering them dendrite-free anodes for alkali metal batteries. Nevertheless, controversy has arisen regarding the suitability of either sodium batteries (NaMBs) or potassium (KMBs) due to presence dual active ions NaK. Based on current research, there is contradiction feasibility making NaK suitable NaMBs through cathode size effect (e.g., Na3V2(PO4)3), and KMBs ion reaction priority K+....
