“…The L -cysteine molecule has different functional groups, including -NH 2 , -COOH, and -SH, exhibiting a strong tendency to coordinate inorganic cations, such as Sn 2+ . [ 46,47 ] During the ESD process, the precursor solution is atomized into aerosol (composed of the charged droplets) on applying a high voltage between the nozzle and substrate. The charged droplets are then attracted to and deposited on the heated substrate.…”

A General Strategy to Fabricate Carbon‐Coated 3D Porous Interconnected Metal Sulfides: Case Study of SnS/C Nanocomposite for High‐Performance Lithium and Sodium Ion Batteries

Transition metal sulfides have a great potential for energy storage due to the pronouncedly higher capacity (owing to conversion to metal or even alloy) than traditional insertion electrode materials. However, the poor cycling stability still limits the development and application in lithium and sodium ion batteries. Here, taking SnS as a model material, a novel general strategy is proposed to fabricate a 3D porous interconnected metal sulfide/carbon nanocomposite by the electrostatic spray deposition technique without adding any expensive carbonaceous materials such as graphene or carbon nanotube. In this way, small nanorods of SnS are generated with sizes of ≈10–20 nm embedded in amorphous carbon and self‐assembled into a 3D porous interconnected nanocomposite. The SnS:C is directly deposited on the Ti foil as a current collector and neither conductive additives nor binder are needed for battery assembly. Such electrodes exhibit a high reversible capacity, high rate capability, and long cycling stability for both lithium and sodium storage.

“…Unlike the usual case that the polymer totally decomposes into amorphous carbon, owing to the catalytic effect of Fe, the amorphous carbon on the surface of Fe 3 C turns into graphitic carbon, resulting in Fe 3 C/graphitic carbon core‐shell structures. Recently, biomolecular‐assisted synthetic methods are considered as promising approaches for preparing nanosized materials, and l ‐cysteine has attracted great attention as a complexing, reducing agent, and simultaneously being a sulfur source . (For the l ‐cysteine molecule, there are various functional groups, namely, –NH 2 , –COOH, and –SH, which have a strong tendency to coordinate with inorganic cations and metals.…”

Much attention has been paid to increase the energy density of Li‐ion batteries, in order to fulfill the requirements of electric vehicles and grid‐scale energy storage. While for anodes various options are available, this is not at all the case for cathodes. In this context, the inexpensive and environmentally benign iron sulfides have been investigated as cathode materials due to the remarkably high capacity based on the conversion reaction. Here, the preparation of FeS nanodots accommodated in porous graphitic carbon nanowires is reported via a combination of electrospinning technique and biomolecular‐assisted hydrothermal method. These materials exhibit excellent electrochemical performances also as cathode materials, with energy densities even higher than the current LiCoO2 intercalation cathode. Moreover, key problems of conversion reaction, such as the low degree of reversibility, large polarization are far‐reachingly mitigated.

“…Owing to the functional groups in the molecules (–SH, –NH 2 , and –COOH), l -cysteine molecule is commonly employed for the preparation of metal sulfides with different morphologies [ 7 , 24 ]. These functional groups usually lead to the versatile role of l -cysteine during the synthetic process, such as sulfur sources, polydentate ligands, self-assembly reagent, or even shape-controlling agent [ 25 – 32 ]. When Mn 2+ and l -cysteine were mixed in the solvent, a complex between Mn 2+ and l -cysteine will form, leading to the formation of nanoplates at the initial stage.…”

MnS has been attracting more and more attentions in the fields of lithium ion batteries (LIBs) because of its high energy density and low voltage potential. In this paper, we present a simple method for the preparation of urchin-like γ-MnS microstructures using l-cysteine and MnCl2 · 4H2O as the starting materials. The urchin-like γ-MnS microstructures exhibit excellent cycling stability (823.4 mA h g−1 at a current density of 500 mA g−1, after 1000 cycles). And the discharge voltage is about 0.75 V, making it a good candidate for the application as the anode material in LIBs. SEM, TEM, and XRD were employed to inspect the changes of the active materials during the electrochemical process, which clearly indicate that the structural pulverization and reformation of the γ-MnS microstructures play important roles for the maintenance of the electrochemical performance during the charge/discharge process.
