Revealing the Electrochemical Charging Mechanism of Nanosized Li2S by in Situ and Operando X‑ray Absorption Spectroscopy

Lithium sulfide (Li2S) is a promising cathode material for lithium–sulfur (Li/S) cells due to its high theoretical specific capacity (1166 mAh g–1) and ability to pair with nonmetallic lithium anodes to avoid potential safety issues. However, when used as the cathode, a high charging voltage (∼4 V v...
