“…The uneven particle size distribution may affect their electrochemical performance, which may originate from the surface reconstruction induced by the addition of cobalt in the lattice. As reported earlier, a proper Co substitution in LNMCO can affect the formation and growth of the primary grains, resulting in the surface reconstruction phenomenon …”

“…It can be seen that the (003) peak shifts slightly to a higher angle position in the modified materials, which is a result of surface cobalt doping induced by sodium volatilization during the high-temperature calcination procedure. When partial cobalt ions enter into the LMNCO lattice, the Co 3+ 3d 6 configurations will overlap with the top of the O 2– 2p band. , Then, the binding force between cobalt and the surrounding oxygen ions increases, resulting in the decrease in the crystal plane spacing. With the continuous addition of cobalt and sodium content, the shift degree of the peak (003) becomes increasingly.…”

“…As reported earlier, a proper Co substitution in LNMCO can affect the formation and growth of the primary grains, resulting in the surface reconstruction phenomenon. 18 TEM measurement was employed to identify the detailed microstructure and morphology of the 3-LMNCO@NCO sample, and the results are shown in Figure 3. Figure 3a presents that the 3-LMNCO@NCO sample is composed of hexagonal particles and the particle size distribution is more uniform, which is consistent with the SEM results as aforementioned.…”

Lithium-rich manganese-based materials are currently considered to be highly promising cathode materials for next-generation lithium-ion batteries due to their high specific capacity (>250 mA h g −1 ) and low cost. A key challenge for the commercialization of these lithium-rich manganese-based materials is their poor rate performance, which is caused by the low electronic conductivity and increasing interface charge transfer resistance produced by the side reaction during the cycling procedure. In this work, we try to improve the rate performance of a lithium-rich manganese-based material Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 using a collaborative approach with Co-doping and Na x CoO 2 -coating methods. Cobalt doping can improve the electronic conductivity, and Na x CoO 2 coating provides a convenient lithium-ion diffusion channel and moderately alleviates the inevitable decrease in cycling stability caused by cobalt doping. Under the synergistic effect of these two modification strategies, the surface and internal dynamics of the Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 material are enhanced and its rate performance is considerably improved without decay of the cycle stability.

these two phenomena and it is now understood that EEE are both part of the environmental cure and the environmental disease: while the increasing production and disposal of EEE have harmful consequences to the planet, [1] the use of EEE can assist in saving energy and natural resources. The research concerning ecofriendly electronics increased greatly in recent decades due to environmental legislations becoming increasingly rigorous and because of the increase in eco-friendly sought devices, which required business models to adapt in order to participate in this new market share. The concepts of eco-friendly electronics or green electronics comprehends several dimensions of this electronic-environment relationship and has been used loosely for a myriad of initiatives. Hu and Ismail [2] explain that the concept may be used to refer to the i) manufacturing process, through the employment of environmentally friendly processes and the avoidance of hazardous components or chemicals; ii) waste generation (avoidance), via reducing the e-waste impacts through the use of cleaner materials, longer product life, introducing programs to raise awareness and promote reuse/recycling; iii) use of sustainable practice (green computing), through the responsible use of computer resources, for example, by powering down and up devices according to need, reducing energy consumption during inactivity; iv) design, through the development of more efficient components that required less energy to perform, reduce carbon emissions, produce less heat, etc. Yet eco-friendly electronics can also refer to electronics whose purpose is to assist the environment or that do so as a consequence of its main function. Both these groups may be understood as an overlap between the aforementioned categories, and are equipment that optimize energy usage, minimize carbon footprint, detect pollutant concentration, monitor oil spillage, generate renewable energy, etc. There are many and diverse examples of these, such as power electronics, smart grids, and photovoltaic systems. [3] This review is intended to discuss these interactions, define important concepts, and provide an extensive list of ways in which EEE can be eco-friendly, primarily focusing on information and communication technology (ICT) devices, but also addressing items that fall outside of this category such as washing machines and lighting equipment. Initially, the use of electronics in aiding with energy and pollution related Eco-friendliness is becoming an indispensable feature for electrical and electronic equipment to thrive in the competitive market. This comprehensive review is the first to define eco-friendly electronics in its multiple meanings: power saving devices, end-of-life impact attenuators, equipment whose manufacturing uses green processing, electronics that use materials that minimize environmental and health risks, designs that improve lifespan, reparability, etc. More specifically, this review discusses eco-friendly technologies and materials that are being introduced to ...
