Key Points

The study aims to investigate the microstructure of electrodeposited lithium and how it changes during cycling in anode-free solid-state batteries.
Analyzed the microstructure of lithium deposits using microscopic techniques.
Evaluated the impact of different metallic interlayers during cycling.
Assessed the energy density of the solid-state batteries with and without interlayers.
Identified unique microstructural features in electrodeposited lithium with metallic interlayers.
Showed that using interlayers improves the cycling stability of lithium deposits.
Observed enhanced energy density in batteries utilizing metallic interlayers.

Implication

Research examines lithium's microstructure and cycle evolution in solid-state batteries, suggesting improved energy density with metal interlayers.

Abstract

"Reservoir-free" construction of solid state batteries could circumvent the handling of reactive lithium metal foils and further increase the energy density. Metallic interlayers could play an important role in the...
