Enhanced Oxygen Redox Activity and Structure Stability of P2‐Type Manganese‐Based Cathodes Through Medium‐Entropy Strategy

open access: yesAdvanced Science, EarlyView.
A medium‐entropy strategy guided by ionic potential is applied to weaken TM─O bonds and suppress Jahn–Teller distortion in P2‐type cathodes, thereby enhancing the oxygen redox activity and structure stability. A medium‐entropy oxide, Na0.8Li0.1Ni0.1Cu0.1Ti0.1Mn0.6O2, demonstrates a high reversible capacity of 223.7 mAh g−1 and an energy density of 616 ...

A Multifunctional Potent Lewis Acid for In Situ Formation of Poly‐Dioxolane Electrolytes Toward High‐Performance Quasi‐Solid State Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
Conventional polymer electrolytes based on poly‐dioxolane (PDOL) suffer from low ion mobility and unstable interfaces. Here, AlCl3‐initiated in situ polymerized gel PDOL electrolytes (AGPE) form a facile Li+ conduction path and hybrid SEI layers, thus enabling high Li+ conductivity and uniform Li deposition.

Unveiling a Stable Polysulfide Transport Framework in a Fluorine‐Free Li‐S Batteries

open access: yesAdvanced Science, EarlyView.
This work unveils a lithium thiophosphate reaction pathway activated by trigger P2S5 units, which initiate fast self‐assembly and shift the system away from conventional Li‐S reactions. The reversible Li‐P‐S framework delivers stability, safety, and high energy density, while enabling a distinct solid‐liquid hybrid electrochemical mode that provides a ...
