چکیده
To promote the commercial application of sodium ion batteries (SIBs), new high-stability and high-capacity anode materials are needed. Metal oxides show great promise, but significant issues relating to their low electrical conductivity unstable structure during charge storage must be resolved. Herein, a composite consisting pseudohexagonal Nb2O5 (TT-Nb2O5) nanoparticles strongly anchored carbon nanotubes (CNT) through glucose-derived framework (Nb2O5/g-CNT) was synthesised assessed for use as in SIBs. This represents first TT-Nb2O5 The is shown offer high specific capacity (203 mAh g?1 at 0.2 A g?1), good rate capability (53 current density 5 retention (135 between 25 300 cycles). attributed flexibility offered by designed framework, superior linkage two provided bonding glucose derived carbon. work therefore demonstrates scalable route metal future high-performance SIB systems.

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...

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...

Nitrogen-doped bamboo-like carbon nanotubes (N-BCNTs) were synthesised using a facile one-step pyrolysis process. Due to their unique one-dimensional hollow structure and intrinsic high nitrogen content, N-BCNTs exhibit high capacity, superior rate capability, and excellent cycle stability and are, thus, promising anode materials for sodium-ion batteries.

In this research, using phenolic resin as the precursor of carbon and various amounts of ethylene glycol as a pore former, porous samples of hard carbon were synthesized. Samples were characterized by x-ray diffraction (XRD) and N2 adsorption-desorption methods. Broad diffraction peaks represent the amorphous structure of samples. Moreover, the gas adsorption-desorption curves showed that the a...
