Lithium-ion rapid transport mechanism and channel design in solid electrolytes

Abstract

The ionic conductivity in high-performance solid-state electrolytes can reach 10-2 S cm-1 that is equivalent to the conductivity of liquid electrolytes, which has greatly promoted the vigorous development of quasi-solid-state batteries and all-solid-state batteries. Whether in polymer electrolytes, inorganic crystal electrolytes or composite solid electrolytes, the rapid transport mechanism of lithium-ion is the essential criterion used to guide high-performance solid electrolyte design. A comprehensive understanding of the rapid lithium-ion transport mechanism requires to focus on the structural characteristics of the material and developing relevant simulation methods to reveal the structure-activity relationship in rapid ion transport.
