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 کاملComposite of K-doped (NH4)2V3O8/graphene as an anode material for sodium-ion batteries.
A layer structured K-doped (NH4)2V3O8/graphene (K-NVG) was prepared via a hydrothermal route and then used as an anode material for sodium-ion batteries for the first time. The K-NVG nanosheets have a diameter in the range of 200-500 nm. The K-NVG electrode exhibited stable cycling and a good rate performance with a reversible capacity of 235.4 mA h g(-1), which is much higher than the 90.5 mA ...
متن کاملAnode for Sodium-Ion Batteries
DOI: 10.1002/aenm.201500174 The continuous pulverization of alloy anodes during repeated sodiation/desodiation cycles is the major reason for the faster capacity decay. However, if these elements can form a compound (such as Sn 4 P 3 ) after each Na extraction, the pulverization of these elements can be partially repaired and the accumulation of pulverization can be terminated. Therefore, we ca...
متن کاملMn3O4-graphene hybrid as a high-capacity anode material for lithium ion batteries.
We developed two-step solution-phase reactions to form hybrid materials of Mn(3)O(4) nanoparticles on reduced graphene oxide (RGO) sheets for lithium ion battery applications. Selective growth of Mn(3)O(4) nanoparticles on RGO sheets, in contrast to free particle growth in solution, allowed for the electrically insulating Mn(3)O(4) nanoparticles to be wired up to a current collector through the...
متن کاملChemically bonded phosphorus/graphene hybrid as a high performance anode for sodium-ion batteries.
Room temperature sodium-ion batteries are of great interest for high-energy-density energy storage systems because of low-cost and natural abundance of sodium. Here, we report a novel phosphorus/graphene nanosheet hybrid as a high performance anode for sodium-ion batteries through facile ball milling of red phosphorus and graphene stacks. The graphene stacks are mechanically exfoliated to nanos...
