A scalable and long-cycle-life 600 Wh kg^-1 solid-state lithium metal pouch cell.

ABSTRACT: Emerging applications, such as electric aircraft and ships, demand rechargeable batteries with high specific energy. However, current lithium (Li) ion batteries fall significantly short in this regard. Even with Li metal batteries, achieving a high cell-level specific energy (e.g. ≥600 Wh kg^-1) remains a significant challenge. In this study, a synergistic strategy integrating a precisely engineered carbonate-based gel-solid-state electrolyte with a surface-modified Li is proposed. Our in-situ gelation technique confines unstable free carbonate solvent molecules, thereby suppressing the electrolyte-induced parasitic reactions. Furthermore, a bicontinuous gradient polymer layer that regulates Li deposition and improves moisture/oxygen resistance is introduced, enabling damage-free
