Nitrogen doped porous carbon fibres as anode materials for sodium ion batteries with excellent rate performance.
Nitrogen-doped activated porous carbon fibres (ACFs) were prepared as anode materials for Na-ion batteries. They exhibit excellent electrochemical performance, especially rate performance. The excellent rate performance is ascribed to the fibre-like morphology and the facilitated charge transfer. The influence of nitrogen functionalities on charge transfer and electrochemical performance of N-d...
متن کاملLarge‐Area Carbon Nanosheets Doped with Phosphorus: A High‐Performance Anode Material for Sodium‐Ion Batteries
Large-area phosphorus-doped carbon nanosheets (P-CNSs) are first obtained from carbon dots (CDs) through self-assembly driving from thermal treatment with Na catalysis. This is the first time to realize the conversion from 0D CDs to 2D nanosheets doped with phosphorus. The sodium storage behavior of phosphorus-doped carbon material is also investigated for the first time. As anode material for ...
متن کاملRed phosphorus-single-walled carbon nanotube composite as a superior anode for sodium ion batteries.
Sodium ion batteries (SIBs) have been considered as a top alternative to lithium ion batteries due to the earth abundance and low cost of sodium compared with lithium. Among all proposed anode materials for SIBs, red phosphorus (P) is a very promising candidate because it has the highest theoretical capacity (∼2600 mAh/g). In this study, a red P-single-walled carbon nanotube (denoted as red P-S...
متن کاملSingle-walled carbon nanohorns coated with Fe2O3 as a superior anode material for lithium ion batteries.
A novel composite of Fe(2)O(3) and single-walled carbon nanohorns (SWCNHs) was firstly developed via a simple hydrothermal method. As an anode material for lithium ion batteries, a Fe(2)O(3)/SWCNHs composite shows excellent rate performance and cycle stability, even at a high current density of 1000 mA g(-1).
متن کاملNitrogen-doped porous carbon nanosheets as low-cost, high-performance anode material for sodium-ion batteries.
Between the sheets: Sodium-ion batteries are an attractive, low-cost alternative to lithium-ion batteries. Nitrogen-doped porous carbon sheets are prepared by chemical activation of polypyrrole-functionalized graphene sheets. When using the sheets as anode material in sodium-ion batteries, their unique compositional and structural features result in high reversible capacity, good cycling stabil...
