Title: TiS2–Polysulfide Hybrid Cathode with High Sulfur Loading and Low Electrolyte Consumption for Lithium–Sulfur Batteries

Journal Article · · ACS Energy Letters

Sulfur cathodes have a high theoretical capacity of 1675 mAh g–1, making the lithium–sulfur batteries a promising technology for future energy-storage devices. However, their commercial viability is faced with challenges arising from intrinsic electrochemical instabilities and inappropriate cell fabrication parameters. We report here the feasibility of employing TiS2 as a conductive polysulfide adsorbent, which allows the use of a high amount of electrochemically active polysulfides in building a TiS2–polysulfide hybrid cathode. The hybrid cathode exhibits long cycle stability at a C/5 rate over 200 cycles with a high areal capacity and energy density of, respectively, 10 mAh cm–2 and 20 mWh cm–2, exceeding those of commercial LiCoO2. Furthermore, such an enhanced electrochemical performance is obtained in cells with a high sulfur content (65 wt %), high sulfur loading (12 mg cm–2), high sulfur mass (12 mg/cathode), and a low electrolyte/sulfur ratio of just 5 μL mg–1.
