Engineering CoMoO4 in reduced graphene oxide as superior cathode hosts for advanced room-temperature sodium-sulfur batteries

The CoMoO4 decorated reduced graphene oxide (CoMoO4@rGO) is successfully prepared as advanced room-temperature (RT) Na-S battery cathodes. Sodium polysulfides are strongly anchored by the CoMoO4@rGO host and then rapidly converted to lower order products by CoMoO4 catalysis. This work provides a new idea for the design of RT Na-S battery cathode, paving the way for the development of efficient and low-cost energy storage systems.
