Chemical-Delithiation-Induced Surface Reconstruction in Layered Oxide Cathodes for High-Performance All-Solid-State Batteries

Abstract Developing all-solid-state batteries (ASSBs) based on high-capacity cathodes (e.g., Ni-rich and Li-rich layered oxides) offers a promising route toward next-generation batteries with high energy density and safety. However, under high voltage, the cathode/solid electroly...

Electrochemically In Situ Formed Inverse‐Honeycomb Local Ordering for Low‐Voltage‐Hysteresis Oxygen Redox in Na/Li Layered Oxide Cathodes

ABSTRACT In oxygen‐redox cathodes, voltage hysteresis largely arises as oxygen redox generally proceeds with electrochemical reactions followed by chemical reactions that normally drive asymmetrical charge and discharge pathways. Although different superstructures, such as ribbon...
