“…Note that the SEI resistance may be contained in the only semicircle, which is difficult to distinguish and does not form a single semicircle at high frequency. The semicircle of SiO@C-1 is the smallest compared with SiO@C-2 and SiO@C-3, suggesting that the smaller particle size of the SiO@C electrode exhibits faster charge transfer when the electrolytes are sufficient. , …”

“…It indicates that the large semicircle in the high-frequency region is due to the formation of a thick SEI film . In addition, the charge-transfer resistances of the SiO@C-1 are much larger than those of the SiO@C-2 and SiO@C-3 when the electrolyte is insufficient. , Figure f and g displays the AC internal resistance and the thickness change of pouch cells in the cycling process, respectively.

Silicon monoxide (SiO) has attracted growing attention as one of the most promising anodes for high-energy-density lithium-ion batteries (LIBs), benefiting from relatively low volume expansion and superior cycling performance compared to bare silicon (Si). However, the size of the SiO particle for commercial application remains uncertain. Besides, the materials and concepts developed on the laboratory level in half cells are quite different from what is necessary for practical operation in full cells. Herein, we investigate the electrochemical performance of SiO with different particle sizes between half cells and full cells. The SiO with larger particle size exhibits worse electrochemical performance in the half cell, whereas it demonstrates excellent cycling stability with a high capacity retention of 91.3% after 400 cycles in the full cell. The reasons for the differences in their electrochemical performance between half cells and full cells are further explored in detail. The SiO with larger particle size possessing superior electrochemical performance in full cells benefits from consuming less electrolyte and not being easier to aggregate. It indicates that the SiO with larger particle size is recommended for commercial application and part of the information provided from half cells may not be advocated to predict the cycling performances of the anode materials. The analysis based on the electrochemical performance of the SiO between half cells and full cells gives fundamental insight into further Si-based anode research.

and electric vehicle broadly, [1] while the lower lithium resource reserve in the earth limits the application for the large scale energy storage in the future. Owing to the earth abundant element reserve of Na in the earth's crust and excellent electrochemical performance of sodium-ion battery, which is an alternative choice to meet the large-scale energy storage system (ESS) for the construction of smart grid and energy internet.Solid sodium-ion battery enjoys high security, high energy density, and shape variability, which is very promising for the application in large-scale ESS. [2,3] Solid electrolytes are key component to provide the transfer of charges by ion movement between two electrodes. However, the low ionic conductivity and poor interface between solid electrolyte and electrode limit the industrial application of solid sodium-ion battery. It is very important for the comprehensive understanding of solid electrolyte/electrode interface mechanism and science and technology problem, as well as the development tendency of solid sodium-ion battery.The overall sodium-ion battery technologies have been reviewed broadly. However, solid electrolyte and interface is rarely concerned yet. Review on sodium-ion battery solid electrolyte and interface is meaningful to design solid sodium-ion battery and improve the safety. The research focus on Na-ion batteries has drastically increased in recent years after 2010, our review mainly provides detailed and comprehensive research progress for sodium-ion battery solid polymer electrolyte and inorganic solid-state electrolyte systems (Figure 1).

Sodium (Na)‐based batteries, as the ideal choice of large‐scale and low‐cost energy storage, have attracted much attention. Na metal anodes with high theoretical specific capacity and low potential are considered to be one of the most promising anodes for next‐generation Na‐based batteries. However, the high reactivity of Na metal anodes makes the electrode/electrolyte phase unstable, resulting in formation of Na dendrites, short cycle life and safety problems. Herein, the contribution outlines the latest development of Na metal anodes for Na metal batteries. The design strategies for high efficiency utilization of Na metal anodes are elucidated, including sophisticated electrode construction, liquid electrolyte optimization, electrode/electrolyte interface stabilization, and solid electrolyte adaptation. Finally, the future research direction and existing problems are proposed.
