“…O 5 , has been attracting much attention, as it offers the essential advantages of low cost, abundant sources, and better safety relative to commercial cathodes such as LiCoO 2 and LiNiO 2 . 89 However, recently it has received increasing attention due to its strong interaction with polysulphides. 90,91 As early as 2009 and 2010, there were two works that reported V 2 O 5 -S composites as cathode materials for Li-S batteries.…”

Lithium-sulphur (Li-S) batteries are one of the most promising candidates for the next generation of energy storage systems to alleviate the energy crisis. However, Li-S batteries' commercialization faces the challenges of low active materials utilization, poor cycling life, and low energy density. Recently, tremendous progress has been achieved in improving the electrode performances and tap density by using the nanostructured metal compounds in Li-S batteries. In this review, we not only present the latest various nanostructured metal compounds applications in Li-S batteries, including metal oxides, metal sulphides, metal carbides, metal nitrides, and metal organic frameworks, but also we focus on the interaction mechanisms between these polar metal compounds with polysulphides. The issues and bottlenecks of these metal compounds are concluded and the corresponding available solutions to address these issues are proposed. This systematic discussion and proposed strategies can offer avenues to the practical application of Li-S batteries in the near future.

“…As a solution, one can force polymer and inorganic phases to interact at a molecular level and upscale the physical properties of the ultimate composite material (7,8). A standard technique for hybrid organic-inorganic material formation uses either hollow particles (9)(10)(11) or capsules (12,13). Due to their ability to encapsulate versatile functional cargos; these methods gained wide applications in catalysis (14), drug-delivery systems (15,16), biology (17), coatings (18,19), and so on.…”

An appropriate approach has been used for the preparation of silica/P(MMA-co-St) hybrid nanoparticles through converting previously prepared inverse miniemulsions into a direct miniemulsion and consequently, using the droplet nucleation polymerization technique. In the early stage of the procedure, silica particles were synthesized from TEOS in the presence of NH 4 OH or HCl as a catalyst through a base or acid-catalyzed sol-gel process. TEOS, ethanol and tirmethoxyvinylsilan were mixed in MMA:St (50:50) to create the inverse miniemulsion I, similarly CTAB, NH 4 OH/HCl and distilled water were dispersed into MMA:St (50:50) and called inverse miniemulsion II. Then, the two mentioned inverse miniemulsions were emulsified in water to achieve direct miniemulsion. The nature of the catalyst and TEOS concentration varied, for the aims of investigation, their effect on the morphology and size of hybrid nanoparticles. This route provided a unique process for silica/polymer hybrid nanoparticles production, avoiding organic solvents. Transmission electron microscopy micrographs revealed that, the morphology of the hybrid nanoparticles can be controlled by the nature of the catalyst.

“…In recent years, there has been a great deal of interest in the fabrication of uniformly sized hollow microspheres, as they can be used to encapsulate inorganic or organic materials and for the manufacture of advanced materials [1,2]. The sacrificial core process is one of the most frequently used techniques to produce hollow inorganic spheres [1][2][3][4][5][6][7][8][9][10][11][12].…”

Poly(1-methylpyrrol-2-yl)squaraine (PMPS) particles have been characterised using SEM. The PMPS particles were used as templates to prepare bare silica and iron-silica hollow spheres, which were characterised using TEM and SEM. The PMPS particles and the hollow spheres are not uniformly sized and are agglomerated. The hollow spheres with larger diameters ([900 nm) contain an internal 'Russian doll' structure. The iron-silica hollow spheres are fused to one another, and the hollow spheres have a heterogeneous wall thickness. The silica and ironsilica hollow spheres both aggregate by size. There are two different size populations (for the diameter) of the bare silica and iron-silica hollow spheres. The smaller silica spheres have thinner walls compared to the larger silica hollow spheres. The larger silica hollow spheres and the iron-silica hollow spheres have similar wall thicknesses. The iron compound in the iron-silica hollow spheres has an oxidation state of 3? and is crystalline.
