Abstract

All-solid-state lithium batteries (ASSLBs), receiving extensive attentions and studies, exhibit better safety, environmental friendliness, stability, wider electrochemical stability window and higher energy density than traditionally liquid lithium batteries. In a variety of inorganic materials, with highly replaceable, the non-lithium metal elements emerge in endlessly and affect performances in diversiform ways. Due to facile preparation, convertible structures and excellent properties, the lithium-containing bimetallic granular materials are often applied as important components of electrolytes in lithium batteries. In this review, in terms of the properties of substituted elements, changing crystal structures, increasing vacancies or defects and improving the interfacial conductions, the roles of metal element substitutions of inorganic particles on the improvement of solid-state electrolytes are expounded. And the applications of substituted strategies in ASSLBs as the host of inorganic particles electrolytes and as fillers or modifications for composite electrolytes are also investigated and discussed. It also summarizes the current concerns and obstacles that need to be broken through, as well as provides a basis guide for the selection and optimization of inorganic particles.
