Structural and electrochemical evolution of alloy interfacial layers in anode-free solid-state batteries

"Anode-free"solid-state batteries exhibit improved safety and have high energy density due to the lack of active material at the anode. To enable this technology, it is necessary to spatially control the evolution of lithium during the charge and discharge of the battery. This work focuses on understanding the influence of alloy interfacial layers on lithium growth and removal during battery operation, and it
