Near‐Micron Single‐Crystalline Mn‐Rich Cathodes With Exceptional Cycling Stability

ABSTRACT Achieving high‐energy‐density and long‐term cycling stability in Mn‐redox‐based cathodes is a critical step toward advancing Ni‐ and Co‐free Li‐ion chemistries to diversify supply chains and lower battery costs. Here, we demonstrate an unusually high performance benchmar...

Lamination Pressure Governs the Effectiveness of Sn Buffer Layers in Low-Pressure All-Solid-State Lithium Metal Batteries

Abstract All-solid-state lithium-metal batteries require stable Li plating/stripping under low stack pressures relevant to practical operation. Here, Sn was used as a model Li-alloying buffer layer to clarify how lamination pressure affects interfacial stability. By independently...
