“…Triggered by the rapid development of wearable electronics and electric cars, advanced energy-storage systems have shown wide application prospects. − Among them, a great deal of efforts have been devoted to develop sodium-ion batteries (SIBs) due to their high energy density and resource abundance, while leading to series of exploring activities. − In searching for suitable anode materials for SIBs, nickel-based materials have been investigated by researchers, accompanied with considerable progress. − Benefiting from a high theoretical specific capacity (591.0 2 mAh g –1 ) and great conductivity, NiS has been deemed as an ideal anode material for SIBs . However, the electrochemical applications of NiS were still limited by the huge volume expansion and serious side reactions, resulting in inferior cycling capabilities and rate performance.…”

Owing to its fascinating properties (such as high theoretical specific capacity and considerable conductivity), nickel sulfide (NiS) was investigated comprehensively as an anode material in sodium-ion batteries. However, they still suffered from volume expansion and sluggish kinetics, resulting in serious cycle capabilities. Herein, through controlling the kind of molten salts (Na 2 SO 4 , NaCl, and Na 2 CO 3 ) in salt melt synthesis (SMS), a series of NiS with an N, S-codoped carbon layer was successfully prepared, accompanied with different morphologies and structures (earthworm-like belts and triangular and spherical particles). Tailored by the ionic strength and viscosity of molten salts, the as-prepared samples displayed different crystallization behaviors, bringing about a difference in electrochemical performance. As earthworm-like NiS@C was explored as an anode material for SIBs, an initial capacity of 712.5 mAh g −1 at 0.5 A g −1 could be obtained, and it still kept 527.4 mAh g −1 after 100 cycles. Even at 2.0 A g −1 , a capacity of 508.6 mAh g −1 could be achieved. Meanwhile, with the assistance of detailed kinetic analysis, the rapid diffusion behaviors of Na + and redox reaction mechanisms of as-fabricated samples were proven for the enhanced electrochemical properties. Given this, this work is expected to provide a method for designing the morphology and structure of metal sulfides, while shedding light on the orientation of fabricating advanced electrode materials for SIBs.

“…Manganite (γ‐MnOOH), as the most stable polymorph of the trivalent manganese oxohydroxide, has raised high concerns due to its potential application as catalysts for redox reactions and as an effective precursor to synthesize lithium manganese oxides for rechargeable lithium‐ion batteries . Meanwhile, it can be easily transformed into several different manganese oxides, such as MnO 2 , Mn 2 O 3 and Mn 3 O 4 , which are promising options in catalysis, biosensor and energy storage . The performance of manganese oxide and oxohydroxide in most applications could be potentially enhanced owing to its one‐dimensional nanostructures with fine‐tuned compositions .…”

A green chemistry approach was successfully fabricated in this work to synthesize γ-MnOOH nanorods under mild conditions, in which oxygen was used as the green oxidizer and no surfactants or templates were involved. Only the oxygen was bubbled through the solutions of divalent manganese in the presence of NaOH. The morpholgy and structure of γ-MnOOH were dependent on several cruicial factors, i. e. the amount of glacial acetic acid (HAc), the kind of anions, reaction time, and reaction temperature. To gain mechanistic information on the dependence, the γ-MnOOH nanorods were characterized by TEM, SEM and XRD. Results showed that γ-MnOOH nanorods were evolved from Mn 3 O 4 by a redox process. Furthermore, the corresponding β-MnO 2 , α-Mn 2 O 3 , Mn 3 O 4 were prepared by calcining γ-MnOOH nanorods under different temperature and atmosphere. Among them, β-MnO 2 nanorods were most efficient for the catalytic decomposition of O 3 .
