A new family of sulfur‐rich phosphorus sulfide molecules (P 4 S 10+ n ) and their electrochemical reaction mechanism with metallic Li has been explored. These P 4 S 10+ n molecules are synthesized by the reaction between P 4 S 10 and S. For Li batteries, the P 4 S 40 molecule in the series of P 4 S 10+ n molecules provides the highest capacity, which has a first discharge capacity of 1223 mAh g −1 at 100 mA g −1 and stabilizes at approximately 720 mAh g −1 at 500 mA g −1 after 100 cycles. This new class of sulfur‐rich P 4 S 10+ n molecules and its electrochemical behavior for room‐temperature Li + storage could provide novel insights for phosphorus sulfide molecules and high‐energy batteries.
