Potassium-selenium (K-Se) batteries have attracted increasing attention for their potential as stationary energy storage systems due to their high theoretical energy density and low cost. The major challenges of these batteries are the low utilization of active selenium, sluggish kinetics, and the volume change during cycling. Herein, a N and O dual-doped porous carbon nanocage anchored with carbon nanotubes (CNTs) (denoted as NO-nanocage/CNT) is designed as a host for Se. This material combines multi ple advantages, such as abundant N/O active sites and excellent electrical conductivity, to realize highly efficient immobilization of Se and polyselenide and fast redox kinetics. The hollow carbon skeleton, with abundant micro and mesoporous structures, shortens the diffusion distances between the ions/electrons and accommodates the volume expansion of the active materials. Density functional theory calculations further confirm that the NO-nanocage/CNT exhibits strong chemical affinity to K 2 Se, which is in agreement with the experimental results. The Se@NO-nanocage/CNT cathode displays a remarkable reversible capacity (623 mAh g −1 at 0.1 A g −1) and an ultra-long cycle life (274 mAh g −1 after 3500 cycles at 1.0 A g −1). The design presented in this paper offers a new approach for the design of multifunctional Se hosts for advanced alkali metal-chalcogen batteries.

“…The utilization of biomass for carbon production is a cost‐effective and eco‐friendly approach because it enables recyclability of different waste materials. [ 29 ] Various biomass materials such as lotus stem, [ 14 ] peat moss, [ 22 ] spring onion peel, [ 24 ] corn stalks [ 28 ] and so on had been used as the carbon source to get new carbon materials as anode for SIBs. Although most of these carbon materials derived from biomass can demonstrate a considerable specific capacity, their low initial coulombic efficiency (ICE) and poor rate performance should be overcome for application.…”

In order to improve the cycling capability and rate performance of carbon anode material for sodium ion battery, an easy, green, and scalable thermal pyrolysis method is exploited to synthesize the nitrogen, phosphorus dual-doped carbon nanosheets from abundant biomass of peach kernel shell and diammonium hydrogen phosphate. This biomass carbon material demonstrates a super-thin nanosheet microstructure, and its surface area reaches about 2262 m 2 g -1 . This carbon nanosheet electrode exhibits a large initial coulombic efficiency of 90%, superior rate capability, and high sodium ion storage capacity. It delivers a high Na + storage capacity of about 332 mAh g -1 at a current density of 100 mA g -1 after 200 cycles. Even at a high current density of 4 A g -1 , a good rate performance of 270 mAh g -1 is also achieved. The ultra-high pseudocapacitance contribution over 90% is the major reason for the excellent Na + storage performance of this carbon nanosheet electrode. This nitrogen, phosphorus doped biomass carbon anode material with an excellent storage capacity of sodium ion, makes it an appealing candidate for cheap and high-performance anode materials for sodium ion batteries.

Sodium-ion batteries (SIBs) were investigated as recently as in the seventies. However, they have been overshadowed for decades, due to the success of lithium-ion batteries that demonstrated higher energy densities and longer cycle lives. Since then, the witness a re-emergence of the SIBs and renewed interest evidenced by an exponential increase of the publications devoted to them (about 9000 publications in 2019, more than 6000 in the first six months this year). This huge effort in research has led and is leading to an important and constant progress in the performance of the SIBs, which have conquered an industrial market and are now commercialized. This progress concerns all the elements of the batteries. We have already recently reviewed the salts and electrolytes, including solid electrolytes to build all-solid-state SIBs. The present review is then devoted to the electrode materials. For anodes, they include carbons, metal chalcogenide-based materials, intercalation-based and conversion reaction compounds (transition metal oxides and sulfides), intermetallic compounds serving as functional alloying elements. For cathodes, layered oxide materials, polyionic compounds, sulfates, pyrophosphates and Prussian blue analogs are reviewed. The electrode structuring is also discussed, as it impacts, importantly, the electrochemical performance. Attention is focused on the progress made in the last five years to report the state-of-the-art in the performance of the SIBs and justify the efforts of research.
