“…Second, the shell can improve the conductivity for the active materials. 47,[49][50][51][52][53][54] High conductivity could lead to small polarization and high capacity. Third, the shell can protect the core materials with nanostructure from aggregating into lager particles and could provide bigger specific area and improve the capacity.…”

With high theoretical specific capacity and favorable electrochemical properties, CuS is considered to be the ideal cathode material for hybrid Mg-Li ion batteries. However, the traditional CuS cathodes exhibit inferior rate performance and poor cycle stability, which limits the development and application of CuS. In this work, CuS@MoS2 with core–shell structure was prepared by two-step hydrothermal synthesis. When utilized for hybrid Mg-Li batteries, CuS@MoS2 displayes high special capacity and stable cycling performance. At current density of 50, 100 and 300 mAg−1, the first discharge capacity is 337.40, 276.28 and 254.58 mAhg−1 which are all higher than those of single CuS and MoS2. More importantly, the discharge capacity of core–shell CuS@MoS2 can remain 104.70 mAhg−1 at 100 mAg−1 after 50 cycles. These performance improvements are contributed to rich reaction sites and high conductivity of mixed metal sulfides. Furthermore, core–shell structure could relieve the volumetric change and remain structure stability for active materials. In conclusion, core–shell CuS@MoS2 could offer a new strategy for the design of high-performance cathode.

“…However, carbon-based materials show significant polarization following a few cycles, which is attributed to their poor catalytic activity and instability during the charging and discharging processes. As alternatives, metal oxides are currently being employed as electrodes, and among them, nanostructured titanium dioxide (TiO 2 ) has received much attention, but it does not fully satisfy all application requirements [20,22]. Regarding this, titanium dioxide-based nanocomposites are regarded as promising electrode materials and have garnered a lot of interest since they can improve the functionality of already existing devices, such as the Li-ion battery and make future-oriented devices such as Li-O 2 and Li-S battery, more practical [22][23][24].…”

Energy storage technology is a valuable tool for storing and utilizing newly generated energy. Lithium-based batteries have proven to be effective energy storage units in various technological devices due to their high-energy density. However, a major obstacle to developing lithium-based battery technology is the lack of high-performance electrode materials with a long lifespan, superior rate capability, and high safety standards. Thus, the rational design of highly reliable electrode materials is crucial when considering the development of high-performance lithium-based batteries for sustainable energy storage. As a result, titanium dioxide-based nanocomposites have gained a lot of interest as potential electrode materials for lithium-based batteries due to their unique properties such as structural characteristics, low cost, safety, and environmental friendliness. Therefore, this chapter gives an overview of the properties, preparation methods, and application of titanium dioxide-based nanocomposites as anode and cathode active materials for high-performance lithium-based batteries.

In the current investigation, a new urchin-like nanostructure using an authorized one-pot precipitation technique was synthesized using Taguchi statistical design. The effect of factors, including the concentration of FeSO4⋅7H2O, KMnO4, NaOH, and reaction temperature, on the diameter-to-length ratio of the nanoneedles and the regularity or irregularity morphology of other samples, was investigated. KMnO4 and FeSO4⋅7H2O, with a contribution of 32.62% and 30.9%, had the most substantial effect on the nanoneedles' diameter. The surface morphology and chemical composition of the as-prepared samples were studied using field emission scanning electron microscopy, X-ray diffraction, and energy dispersive spectroscopy (EDX) analyses. The length and needle diameter was obtained 140 and 17 nm, respectively. The result of BET analysis for the highest and the lowest value of D/L shows that the smallest ratio of diameter to length has a high specific surface area. The results show that sample S4 has a particular surface area of 74 m2/g, much more than S3 (25 m2/g). The estimated crystallite size in synthesized S3 and S4 samples are 41.64 and 26.49 nm, respectively.
