Article Synopsis
- - Layered oxide cathodes face structural issues during cycling, leading researchers to explore a heterostructure strategy that incorporates stable components to improve cycle stability.
- - This study focuses on lithium cobalt oxide (LiCoO) and uses its low-temperature form as a strain-retardant within the cathode, showcasing complex configurations that enhance stability.
- - Despite improvements in structural integrity, the composite cathode shows slow lithium-ion transport, highlighting the challenges of material selection and the importance of heterostructure strategies in advancing Li-ion battery technologies.

Anode-free lithium metal batteries (AF-LMBs) can deliver the maximum energy density. However, achieving AF-LMBs with a long lifespan remains challenging because of the poor reversibility of Li plating/stripping on the anode. Here, coupled with a fluorine-containing electrolyte, we introduce a cathode pre-lithiation strategy to extend the lifespan of AF-LMBs.
