“…Recent research has also looked into inexpensive cations suchas sodium (Na), and for multivalent cations that could lead to higher energy through increasing the number of electrons, e.g. magnesium (Mg) and even having multiple possible oxidation states as iron (Fe)[221,222]. Also, of recent interest is the Zinc-Air battery, where…”

Carbon Black (CB) is one of the most abundantly produced carbon nanostructured materials, and approximately 70% of it is used as pigment and as reinforcing phase in rubber and plastics. Recent scientific findings report on other uses of CB that are of current interest, such as renewable energy harvesting and carbon capture. The present review focuses on the use and role of CB in renewable and environmental applications relevant to contemporary global challenges focusing specifically on clean energy. Key and recent research on the structure and chemistry of CB, including its uses as precursors to graphene quantum dots and hollow carbon spheres, is discussed in relation to renewable energy devices, electrochemical energy storage and environmental remediation. The surface chemistry of CB is closely related to that of graphitic and of turbostratic carbons through the predominant hexagonal carbon lattice from graphene fragments forming its basic structural units. Consequently, modern methods for grafting polymers and functional groups are easily translated to this abundant nanostructured material. Moreover, recent advances in electron microscopy that probe the structure of CB, and its electronic and physicochemical properties in nanocomposites revived the attention of what is wrongfully considered as a scientifically uninspiring material with limited potential for future technology breakthrough. CB has the potential to surge as a key player in renewable energy and environmental applications, meaning "When Black Turns Green".

“…Among vanadium oxides, vanadium pentoxide V 2 O 5 , which has the highest oxygen content 1 , is of paramount importance since its properties are highly sensitive to external factors, so it is used in photocatalysts 2 , chemical actuators 3 , optical fibers 4 , gas sensors 5 – 7 , and electrochromic devices 8 . The structure of V 2 O 5 is best described as an arrangement of square pyramid VO 5 units forming layers, which enables high ion storage capacity for batteries 9 – 12 . Recently, it has been found that reversible changes in V 2 O 5 resistivity could be triggered by voltage 13 or temperature 14 , which could be helpful for neuromorphic computing applications 15 and photonic device architectures 16 .…”

We report on the synthesis and characterization of V2O5 nanoparticles grown using a sol–gel method at different calcination temperatures. We observed a surprising reduction in the optical band gap from 2.20 to 1.18 eV with increasing calcination temperature from 400 to 500 °C. Raman and X-Ray diffraction measurements indicated slight changes in the lattice parameters induced by the growth process. However, density functional theory calculations of the Rietveld-refined and pristine structures revealed that the observed optical gap reduction could not be explained by structural changes alone. By introducing oxygen vacancies to the refined structures, we could reproduce the reduction of the band gap. Our calculations also showed that the inclusion of oxygen vacancies at the vanadyl position creates a spin-polarized interband state that reduces the electronic band gap and promotes a magnetic response due to unpaired electrons. This prediction was confirmed by our magnetometry measurements, which exhibited a ferromagnetic-like behavior. Our findings suggest that oxygen vacancies play a crucial role in band gap reduction and the promotion of a ferromagnetic-like response in an otherwise paramagnetic material. This provides a promising route to engineer novel devices.

“…Though lithium-ion batteries continue to dominate worldwide as energy storage devices, sodium-ion batteries (SIBs) have been gaining attention due to their extensive research. [1][2][3] According to research and development, sodium-ion batteries [4][5][6] are the next generation batteries for energy storage applications, among all other types of batteries, including magnesium-ion, 7,8 aluminumion, 9 potassium-ion, 10 calcium-ion, 11 iron-ion, 12 zinc-ion batteries. 13 The sodium has a low redox potential (−2.71 V vs. standard hydrogen electrode [SHE]) comparable to lithium metal (−3.04 V vs. SHE).…”

NASICON (Sodium superionic conductor) type Na3Zr2Si2PO12 (NZSP) has received a lot of interest as the solid electrolyte for all‐solid‐state sodium‐ion batteries (ASSIBs). The electrolyte has superior interfacial characteristics, high thermal stability, and good ionic conductivity. Because of their higher energy density, improved mechanical stability, no liquid leakage problem, and higher operating voltages, All solid‐state batteries are expected to replace liquid electrolyte‐based batteries in many applications. The solid electrolyte also acts as a separator, and hence additional separator is not required for cell operations. Because of its 3D open architecture and continuous diffusion channels, NZSP is considered a better solid electrolyte. The NZSP solid electrolyte has been synthesized by spark plasma sintering (SPS) followed by annealing the sintered materials. The SPS method leads the material to have higher density and ionic conductivity. Conventional sintering of the materials requires a temperature as high as 1225°C; however, the temperature required for the SPS is as low as 1050°C. Moreover, conventional sintering yields samples of relative density up to 91%, while SPSed samples have achieved a maximum density of around 98%. The ionic conductivity of solid electrolyte SPSed at 1050°C for 10 min is found to be 3.5 × 10−4 S/cm with an activation energy of 0.27 eV. The annealing of the SPSed samples improves the ionic conductivity of the SPS1050‐20mins sample to roughly double the value obtained from the as‐prepared SPS sample because there are fewer secondary phases and a structural change from a rhombohedral to a monoclinic system. To ascertain the samples' crystal structure, particle shape, and ionic conductivity, materials were characterized using X‐ray diffraction, scanning electron microscopy, and electrochemical impedance spectroscopy. The samples' mechanical characteristics, for example, the hardness and fracture toughness of the samples, were also determined.
