“…Recently, lithium‐sulfur batteries are attracted considerably due to their high theoretical capacity and ecological and efficient pathway for energy storage 5 . Supercapacitors are among the most interesting types of energy storage mechanisms, and are classified as electric double‐layer capacitance (EDLC) and pseudo‐capacitance 3b,6 . Employing efficient constituent materials, particularly active electrode materials, may help to meet industrial needs for devices using supercapacitors.…”

In this work, we demonstrated the phase-tuned MoS 2 layers (2H-MoS 2 , 1 T-MoS 2 , and 2H/1 T-MoS 2 ) using a one-pot reaction, scientifically significant due to their impermeable characteristics. Strongly-bonded, vertically-aligned layers were perceived by transmission electron microscopy (TEM) for 2H/1 T-MoS 2 layers. The spacing between the two layers was expanded to 0.67 nm, which is favorable for intercalation process. Further, mixed-phase MoS 2 sheets were successively blended with reduced graphene oxide (rGO) to form 2H/1 T-MoS 2 @rGO hybrid. Spectroscopic studies verified the formation of phase-tuned MoS 2 and 2H/1 T-MoS 2 @rGO hybrid. The resulting 2H/1 T-MoS 2 @rGO hybrid TEM micrograph shows the layered MoS 2 lattices decorated rGO nano-structure. Symmetric supercapacitors constructed from 2H/1 T-MoS 2 @rGO hybrid electrodes demonstrated improved storage capacity with solid pseudo-capacitive behavior compared to the pure phases. Surfacemodified 2H/1 T-MoS 2 @rGO nanostructures exhibited a high energy density of 55 WhÁkg −1 at a power density of 3 kWÁkg −1 with a symmetric capacitance of 275 FÁg −1 at a current density of 1 AÁg −1 , along with an excellent cyclic constancy (~97% capacity after 5000 cycles).

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

et al. 2020

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.

Sodium alginate (Na-Alg) is water-soluble, neutral, and linear polysaccharide. It is the derivative of alginic acid which comprises 1,4-β-d-mannuronic (M) and α-l-guluronic (G) acids and has the chemical formula (NaC6H7O6). It shows water-soluble, non-toxic, biocompatible, biodegradable, and non-immunogenic properties. It had been used for various biomedical applications, among which the most promising are drug delivery, gene delivery, wound dressing, and wound healing. For different biomedical applications, it is used in different forms with the help of new techniques. That is the reason it had been blended with different polymers. In this review article, we present a comprehensive overview of the combinations of sodium alginate with natural and synthetic polymers and their biomedical applications involving delivery systems. All the scientific/technical issues have been addressed, and we have highlighted the recent advancements.
