Abstract

The “single-crystal” lithium-rich layered oxide (SC-LLO) material is applied for the first time to construct a composite cathode by a co-sintering process for garnet-based high-energy all-solid-state lithium metal batteries, which exhibit the high initial discharge capacity of ∼226 mA h g⁻¹, and good capacity retention after tens of cycles.
