We focused on solving the ion transport issues of the cross-interface, cross-phase, and cross-gap in solid-state batteries. First, we proposed and illustrated an in-situ interface reaction solid-state mechanism for solid-state battery. A single-crystal oriented lithium anode was constructed by lattice adaptation of interface materials, which realized the interfacial atomic level coupling and cross-interface compatibility. Second, we invented a new coupling method of dielectric and electrolyte ceramic materials, which achieved the efficient dissociation of lithium salt and the spontaneous across-phase transport of ions. A solid-state electrolyte composite material with high ionic conductivity was developed. Third, we developed a low oxidation potential construction strategy of a robust cathode interface layer and created a solid-polymer-solid elastic cross-gap transfer network of ions, which greatly improve the long cycle performance of all-solid-state battery at room temperature. Based on above innovative research achievements, he proposes a quantizable concept of ion transport throughput, which provides a significant criterion for investigation of all-solid-state battery. In this work, we will introduce how to improve the ion transport throughput in solid-state lithium batteries.
