“…The evolution of energy storage technologies has been driven by the pursuit of safer, more efficient, and environmentally friendly alternatives to conventional lithium-ion batteries. In this context, lithium–sulfur (Li–S) batteries have emerged as a promising candidate for next-generation energy storage systems. − Unlike traditional lithium-ion batteries, which rely on intercalation chemistry, − Li–S batteries store energy through a conversion reaction between lithium and sulfur . The appeal of Li–S batteries lies in their high theoretical energy density, which significantly surpasses that of lithium-ion batteries.…”

Lithium−sulfur batteries hold great promise for energy storage because of their high theoretical capacity, cost-effectiveness, and environmental friendliness. However, their commercialization has been hindered by the low conductivity of the discharge product lithium sulfide (Li 2 S) and its high oxidation energy barrier, resulting in low sulfur utilization, poor reversibility, and rapid capacity decay. This study investigates the addition of diethyldiselenide (DEDSe) into conventional electrolytes to mitigate Li 2 S deficiencies. The result demonstrates the breakage of the Se−Se bond in DEDSe and the elongation of the Li−S bond in Li 2 S. Moreover, DEDSe reduces the oxidation energy barriers and accelerates the oxidation kinetics of Li 2 S. Quantitative analysis confirms the decrease of irreversible Li 2 S deposition at the electrode. As a result, batteries with DEDSe contents exhibit excellent electrochemical performance. Specifically, cells with 2.0 wt % DEDSe added show a high initial discharge capacity of 1314.2 mAh g −1 in the high sulfur-loading pouch cell, maintaining 992.5 mAh g −1 after 34 cycles, which is significantly higher than conventional electrolyte cells at 562.7 mAh g −1 . This study offers innovative perspectives on addressing practical challenges and improving the cycling stability of lithium−sulfur batteries.
