Dual‐ion batteries (DIBs) are considered one of the promising energy storage devices in which graphite serves as a bi‐functional electrode, i.e., anode and cathode in the aprotic organic solvents. Unlike conventional lithium‐ion batteries (LIBs), DIBs reversibly store the cations and anions in the anode and cathodes during redox reactions, respectively. The electrolyte is a source for both cations...
Sodium metal (Na) anodes are considered the most promising anode for high‐energy‐density sodium batteries because of their high capacity and low electrochemical potential. However, Na metal anode undergoes uncontrolled Na dendrite growth, and unstable solid electrolyte interphase layer (SEI) formation during cycling, leading to poor coulombic efficiency, and shorter lifespan. Herein, a series of Na‐ion...
Artificial SEI Layers
In article number 2300135, Ranjith Thangavel, Yun‐Sung Lee, and co‐workers introduce a simple approach for forming a series of hybrid multifunctional Na‐ion conducting type protective interfaces as the artificial solid electrolyte interphase (SEI) layer. They facilitate rapid Na‐ion transportation and notably inhibit the formation of sodium dendrites. These type of hybrid interfaces...
