Improving Interfacial Stability for All-Solid-State Secondary Batteries with Precursor-Based Gradient Doping.

ABSTRACT: Recently, sulfide solid-state electrolytes with excellent ionic conductivity and facile electrode integration have gained prominence in the field of all-solid-state batteries (ASSBs). However, owing to their inherently high reactivity, sulfide electrolytes interact with the cathode, forming interfacial layers that adversely affect the electrochemical performance of all-solid-state cells. Unlike conventional cathode-coating methods that involve the formation of surface coatings from high-cost source materials, the proposed strategy involves the doping of precursors with low-cost oxides (Nb₂O₅, Ta₂O₅, and La₂O₃) prior to cathode fabrication. This novel approach aims to improve the stability of the cathode-sulfide electrolyte i
