Lithium Plating and Stripping Behaviors of Anode-Free Solid-State Lithium-Ion Batteries Depending on Composition of Protective Layer

Solid-state lithium-ion batteries without anode active materials are one of the most promising types of energy storage methods to improve the energy density of solid-state lithium-ion battery. In this work, we compared lithium plating and stripping behaviors of anode-free solid-state batteries with various anode compositions by means of electrochemical and analytical characterization methods. We found that the electrochemical performance of solid-state lithium ion battery without anode active material is highly dependent on the composition of protective layer. The morphological changes in the anode during lithium plating and stripping will be presented in more detailed in the presentation.
