Functional modules for enhanced amorphous composite halide solid electrolytes for low-temperature all-solid-state lithium batteries

Nature Communications, Published online: 27 May 2026; doi:10.1038/s41467-026-71876-0 Designing improved halide solid electrolytes holds the key to the success of all-solid-state batteries. Here, authors present the design of SSEs through functional modules, introducing LaCl3, which possesses a UCl3 structure, as well as low-cost and low-density AlF3, to enable low-temperature application and improve moisture and high-voltage stability in halide-based solid-state battery systems.
