title: A high-energy room-temperature sodium-sulfur battery.
abstract: Employing small sulfur molecules as the active cathode component for room-temperature Na-S batteries, reveals a novel mechanism that is verified for the batteries' electrochemistry. The sulfur cathode enables a complete two-electron reaction to form Na2 S, bringing a tripled specific capacity and an increased specific energy compared with traditional high-temperature Na-S batteries. At the same time, it offers better cycling stability endowing the batteries with a longer lifespan.
