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...

Screening Lithium-Ion Conductors Based on Local and Global Topology

Abstract The discovery of high-performance solid-state electrolytes remains a critical challenge for all-solid-state Li-ion batteries. To accelerate the identification of novel Li-ion conductors, we developed a hierarchical screening framework combining local structure order para...
