“…The main sharp peak positioned at 183.04 eV corresponds to Zr 3d 5/2 , and a second prominent peak at 185.40 eV represents Zr 3d 3/2 spin–orbital levels of the ZrO 2 . These two peaks further indicate the presence of Zr 4+ in the coated nanocomposite. , …”

“…These two peaks further indicate the presence of Zr 4+ in the coated nanocomposite. 35,42 The CV of NiO and ZrO 2 -coated NiO-MWCNTs is conducted within a voltage window of 0.01−3.0 V, at a constant scan speed of 0.1 mV s −1 , as shown in Figure 5a. Three main reduction peaks are noticed in the initial cycles where an intense reduction peak at 0.24 V is ascribed mainly to the formation of a solid electrolyte interface (SEI), which inherently describes the electrolyte decomposition that appears in the first cycle.…”

A very simple coprecipitation approach is adopted to prepare ZrO2-coated NiO on MWCNTs nanocomposites with NiO nanoparticles within 10–15 nm size. The XPS studies confirm the presence of Zr, Ni, C, and O elements in the sample, while the BET and BJH analyses reveal a typical surface area of 204.44 m2 g–1 with pores between 10 and 15 nm. The electrochemical performance studies of the ZrO2-coated nanocomposite electrode show a higher charge/discharge capacity of 688.3/688.7 mAh g–1 after 200 cycles with excellent retention capacity (96%) and cycling stability. A minor capacity fading has been observed in the rate performance of the electrodes at currents ranging from 100 to 5000 mA g–1. It also reveals that coin cells tend to maintain their maximum Coulombic efficiency of 99.9% at a low current density, revealing a notable reversible capacity. Therefore, adding MWCNTs significantly increases electrochemical performance and prevents pulverization of active materials. While structural flexibility helps in mitigating the volumetric expansion. During the cycling process, the ZrO2 coating helps improve structural stability and facilitate the diffusion of Na ions.

“…Various [102], and WS 2 heterostructures [103] have been developed and doped with carbonaceous materials (carbon agents, carbon nanotubes, and graphene oxide, among other). This carbonaceous doping has the objective of increasing the electrical conductivity and, consequently, the electrochemical properties through conductive pathways to facilitate charge transport and structural buffer space to accommodate volume variations.…”

Recent Advances on Materials for Lithium-Ion Batteries

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.
