Lithium sulfide (Li2S) is a cathode material with great potential to surpass the current lithium-ion technology, boasting high specific capacity comparable typical lithium–sulfur battery and raising cycling ability while being capable of mitigating safety concerns associated lithium metal anodes. However, it suffers from first-charge overpotential, stemming strong ionic bonds that prevent dissociation. Dissolution fluid medium facile approach raise utilization suppress reaction often attributed refinement particle size, where, nevertheless, interaction between Li2S commonly used alcohol solvent overlooked. This study highlights this critical aspect by examining interactions methanol, revealing its multifunctional roles beyond mere solvent. forms multiplex methanol in solution remains stable through conventional drying, where final products conjunction can aid delithiation process significantly. Our results further show when utilizing overpotential be suppressed 3.8 V as low 2.35 V, superior those various other methods, such engineering which require higher energy input. Material characterization electrochemical testing demonstrate control drying Li2S–methanol multiplexes modulate active product during fabrication, supported simulation studies present comprehensive understanding optimizing Li2S-based LSBs. The demonstrates framework engineer particles their not bulk but on molecular level.

Abstract Lithium sulfide (Li 2 S) is a promising electrode material with high specific capacity and can be paired commercial anode materials such as graphite. However, bulk Li S requires activation energy during the initial charge due to its inert electrochemical activity, resulting in overpotential. Here, lithium phenyl selenide (PhSeLi) proposed mediator that effectively activate by altering oxidation pathway process. It enables release normal over general voltage range (1.5–3 V). The composite cathode S:PhSeLi molar ratio of 4:1 exhibits reversible 615.9 mAh g −1 at 0.2 A after 400 cycles all‐solid‐state batteries 7 P 3 11 electrolyte In–Li (the corresponding based on 1016.6 ). In full cell partially pre‐lithiated silicon anode, it still provide an average discharge 524 0.1 844.2 This work will contribute further development S‐based Li–S batteries.
