Electroanalytical methods and their hyphenated techniques for novel ion battery anode research

“…161 Using in-situ optical microscopy, it was revealed that self-healing of cracks in Si-Al electrodes occurred in two steps by arresting of micro-cracks at the Si/Al interfaces and closure of the cracks at the end of the electrochemical cycle. 162 Furthermore, the optical microscopy can record the evolution of the lithium plating between the electrodes positioned in co-planar configuration (Figure 19). 163 This journal is © The Royal Society of Chemistry 20xx…”

Endowing the Lithium Metal Surface with Self-Healing Property via an in Situ Gas–Solid Reaction for High-Performance Lithium Metal Batteries

“…Very recently, Li et al found that extensive surface migration of Li would be triggered by the heat occurred from high current density and led to dendrite healing behavior. Similarly, melting lithium metal anodes , and liquid metal alloys − were also utilized to obtain a self-healing metal anode without dendrites. However, to the best of our knowledge, artificial SEI layers with self-healing behavior are rarely mentioned.…”
