A phosphorene-graphene hybrid material as a high-capacity anode for sodium-ion batteries.
Sodium-ion batteries have recently attracted significant attention as an alternative to lithium-ion batteries because sodium sources do not present the geopolitical issues that lithium sources might. Although recent reports on cathode materials for sodium-ion batteries have demonstrated performances comparable to their lithium-ion counterparts, the major scientific challenge for a competitive s...
متن کاملHigh rate capability and superior cycle stability of a flower-like Sb2S3 anode for high-capacity sodium ion batteries.
Flower-like antimony sulfide structures were prepared by a simple and easy polyol reflux process. When tested as an anode for sodium ion batteries, the material delivered a high reversible capacity of 835.3 mA h g(-1) at 50 mA g(-1) after 50 cycles and maintained a capacity of 641.7 mA h g(-1) at 200 mA g(-1) after 100 cycles. Even up to 2000 mA g(-1), a capacity of 553.1 mA h g(-1) was obtaine...

متن کاملInitial Discharge Capacity of Manganese Cobaltite as Anode Material for Lithium Ion Batteries
Nanostructured manganese cobalt oxide spinel (MnCo2O4) are prepared by co-precipitation method and calcined at 650 and 750°C. Morphological studies show that by increasing the calcination temperature from 650 to 750°C, morphology of the particles changes from quasi-plate to polyhedral. The MnCo2O4 calcined at 650°C could deliver an initial discharge capacity of 1438 mAh g-1 under current densit...
متن کاملAmorphous Sb2S3 embedded in graphite: a high-rate, long-life anode material for sodium-ion batteries.
Amorphous Sb2S3 embedded in a conductive graphite matrix is designed for sodium-ion batteries. Owing to the amorphous structure of the active phase and the conductive graphite matrix, the Sb2S3-graphite electrode exhibits a high initial Coulomblic efficiency, a high rate capacity, and stable cycle performance in sodium-ion batteries.
