Stabilising graphite anode with quasi-solid-state electrolyte for long-life lithium-sulfur batteries.

ABSTRACT: Lithium-sulfur (Li-S) batteries with high energy density are promising for next-generation energy storage but suffer from poor cycle life due to instability of the lithium anode. Commercial graphite anodes used in lithium-ion batteries could be viable for replacement of lithium metal as anode in Li-S batteries. However, graphite anodes are incompatible with the commonly used ether-based electrolytes in Li-S batteries due to the Li⁺ ion and solvent co-intercalation into graphite interlayers, which leads to exfoliation. Here, we report the stabilisation of graphite anode by in-situ formation of quasi-solid-state electrolyte (QSSE) in Li-S batteries. The QSSE is formed by the ring-opening of molecular ethers induced by metallic molybdenum disulfide sulfur cathode host to pro
