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...

Tailoring electrolyte salt concentration to achieve reversible Li storage in pure-Ni layered oxide

Abstract Modulating electrolyte formulation is an efficient strategy to mitigate side reactions at the electrode/electrolyte interface and thereby enhance the cycling stability of lithium batteries. Herein, the effects of electrolyte salt concentration on the solution structure a...

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...
