Abstract

The further enhancement of high-rate capabilities for all solid-state lithium secondary batteries is reported. A LiNbO₃ layer of nanometer thickness was interposed between LiCoO₂ and sulfide solid electrolyte as buffer layer. This greatly reduced the interfacial resistance in the cathode and enhanced the high-rate capabilities of solid-state lithium batteries, providing good prospects for practical application of lithium secondary batteries free from safety issues.
