Gradient‐Modified Li‐Rich Manganese‐Based Oxides Cathodes with Breakthrough of Kinetic Limitation for High‐Performance All‐Solid‐State Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
The novel gradient‐modified LRMO has been synthesized via a one‐step mechano‐fusion process, with simultaneous S and Zr co‐doping in the near‐surface region and an amorphous coating. The synergistic co‐functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential, which enable ...
