Self-adaptive layered oxide cathodes driven by charge reconfiguration for sodium-ion batteries

Abstract Layered oxide cathodes have attracted worldwide attention due to environmentally friendliness, structural diversity, and economic benefits. However, poor long-term cycling and unsatisfactory rate performance hinder the practical application. Hence, an oxide cathode with...

MXene‐Confined Cobalt‐Rich Co 2 P Nanoparticles Enable Highly Reversible Conversion Reaction for Stable and Fast Sodium‐Ion Batteries

ABSTRACT Transition metal phosphides have attracted considerable attention as alternative conversion‐type anodes for SIBs because of their high specific capacities. However, their sodium‐storage mechanism typically shifts to an alloying reaction between P and Na + after the initi...

Charge‐Redistribution‐Driven Dual‐Single‐Atom Catalysts on MXene for Hydrogen Evolution

ABSTRACT The hydrogen evolution reaction (HER) exhibits pH‐ and electrolyte‐dependent pathways, imposing intrinsic challenges on the development of catalysts that operate efficiently across wide pH conditions and in seawater electrolysis. Here, we report a dual‐single‐atom cataly...
