Description
Summary:Highlights Through strategic heterostructure design, it is possible to create electrified interfaces that induce the formation of a fully ionized depletion region and a built-in electric field. These electrified interfaces enhance Li affinity and promote uniform current distribution, leading to stable Li deposition behavior. Owing to intentional design, SnP0.94/CoP heterostructure enables in situ conversion to a mixed ionic/electronic conductor during cycling, ensuring the long lifespan.
