Data from: MnO2–graphene nanosheets wrapped mesoporous carbon/sulfur composite for lithium–sulfur batteries
The lithium-sulfur battery has received intense interest due to its achievable high energy density and low cost sulfur. However, fast capacity retention after a prolonged cycles is the main challenge. Here, we report to synthesis MnO2-graphene nanosheets coated mesoporous carbon/sulfur composite (MGN@MC/S) as cathodes in the Li-S battery. The MGN@MC/S electrode exhibits excellent electrochemical performance, with high reversible specific capacity and rate capability (1475 mA h g-1 at 0.1 C and 748 mA h g-1 at 1 C ), and long-cycle ability (0.042 % capacity decay per cycle over more than 450 cycles at 1 C).
