Stabilized cathode/sulfide solid electrolyte interface via Li_(2)ZrO_(3)coating for all-solid-state batteries

摘要

High-capacity LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)(NCM)cathode is essential for realizing high energy density all-solid-state lithium batteries.However,the space charge layer effect between NCM cathode and the commonly used sulfide solid electrolyte results in deterioration of the battery performance.In this work,a 10-nm electrochemical stable Li_(2)ZrO_(3)(LZO)layer was in situ coated on the surface of NCM particles through facile wet chemical method.
