title: Sulfur-Rich Phosphorus Sulfide Molecules for Use in Rechargeable Lithium Batteries.
abstract: A new family of sulfur-rich phosphorus sulfide molecules (P4S10+n) and their electrochemical reaction mechanism with metallic Li has been explored. These P4S10+nmolecules are synthesized by the reaction between P4S10and S. For Li batteries, the P4S40molecule in the series of P4S10+nmolecules provides the highest capacity, which has a first discharge capacity of 1223 mAh g-1at 100 mA g-1and stabilizes at approximately 720 mAh g-1at 500 mA g-1after 100 cycles. This new class of sulfur-rich P4S10+nmolecules and its electrochemical behavior for room-temperature Li+storage could provide novel insights for phosphorus sulfide molecules and high-energy batteries.
