“…Due to the larger interlayer distance and easier charge transfer properties of fibre‐like morphology, N‐doped porous carbon nanofibers deliver a reversible capacity of 296 mA h g −1 at 0.05 A g −1 when used as anode for SIBs. Yu and co‐workers also designed boron (B), nitrogen (N) codoping 3D interconnected carbon nanofibers (denoted as BN‐CNFs) to enhance sodium storage performance . B, N codoping provides synergistic effects of increased active sites and enlarged carbon layer spacing for Na + insertion and improved electronic conductivity.…”

Sodium-ion batteries (SIBs) have received extensive attention as ideal candidates for large-scale energy storage systems (ESSs) owing to the rich resources and low cost of sodium (Na). However, the larger size of Na and the less negative redox potential of Na /Na result in low energy densities, short cycling life, and the sluggish kinetics of SIBs. Therefore, it is necessary to develop appropriate Na storage electrode materials with the capability to host larger Na and fast ion diffusion kinetics. 1D materials such as nanofibers, nanotubes, nanorods, and nanowires, are generally considered to be high-capacity and stable electrode materials, due to their uniform structure, orientated electronic and ionic transport, and strong tolerance to stress change. Here, the synthesis of 1D nanomaterials and their applications in SIBs are reviewed. In addition, the prospects of 1D nanomaterials on energy conversion and storage as well as the development and application orientation of SIBs are presented.

The investigation of phosphoric acid treatment on the performance of hard carbon from a typical lignocellulosic biomass waste (peanut shell) is herein reported. A strong correlation is discovered between the treatment time and the structural properties and electrochemical performance in sodium-ion batteries. Indeed, a prolonged acid treatment enables the use of lower temperatures, that is, lower energy consumption, for the carbonization step as well as improved high-rate performance (122 mAh g at 10 C).

“…It's acknowledged that the whole electrode process of sodium storage involves reaction process and diffusion process. From this perspective, the anode materials still need fast ion transport besides adsorption mechanism for sodium storage to further improve the rate capability as well . Generally, to accelerate the ion transport, decreasing Na + transport distance is a significant method in the light of “

τ = L^{2} / D

” (here τ, L and D represent diffusion time, diffusion distance and diffusion coefficient respectively) .…”

Ultrafast Sodium Storage through Capacitive Behaviors in Carbon Nanosheets with Enhanced Ion Transport

et al. 2019

Sodium‐ion batteries are regarded as a promising alternative for scalable electricity storage, but the rate capability is still a scientific challenge to be solved, owing to the poor Na+ kinetics in electrodes. Herein, nitrogen‐doped carbon nanosheets with rich defects, nanopores and various interlayer spacings are prepared by pre‐carbonized polymer sheets at different temperatures followed by sodium amide treatment. Combination of thin nanosheets, nanopores and large interlayer spacing can boost the rapid Na+ diffusion, as proven by the calculation of the diffusion coefficient. Meanwhile, the kinetics analysis demonstrates the capacitive behaviors, which favor fast Na+ storage. When applied as an anode, the material exhibits superior rate capability (111.1 mA h g−1 even at 20 A g−1), remarkable cycle stability (over 2000 cycles) and ultrahigh initial coulombic efficiency (81.4 %). Furthermore, this work demonstrates a new way to develop attractive high‐rate carbon anode materials for sodium‐ion batteries.
