Unlocking the hidden chemical space in cubic-phase garnet solid electrolyte for efficient quasi-all-solid-state lithium batteries
Abstract
Conventional compositions of garnet solid electrolytes have limited access to the cubic phase for a high Li content of 7.0, which is beneficial for stability against Li metals. Here, the authors unlock the hidden chemical space via a high entropy strategy, enabling stable long-term battery cycling.
