“…The composition of electronic waste plays a crucial role in determining the extent to which materials may be recovered during recycling procedures (Matsukami et al, 2022). Devices that possess elevated levels of precious metals, rare earth elements, and valuable components are more appealing when considering recycling (Xu et al, 2023).…”

Leveraging the power of a quantitative approach, this study navigates the complex web of e-waste dynamics. E-waste generation rates, recycling rates, and composition intricately shape the e-waste landscape in Asia. Through the meticulous collection of data using Google Forms, respondents across four different countries in Asia contribute their perspectives, making this research a true cross-cultural exploration. The findings, distilled through robust statistical analysis using SPSS, highlight the nuanced correlations that dictate the e-waste management paradigm. The Pearson Correlations table underscores the significant associations between e-waste generation rates, recycling rates, composition, and recycling sustainability. The linkages unveiled through this analysis provide a comprehensive understanding of how these factors interact within the Asian context, guiding the formulation of effective e-waste management strategies. Furthermore, the regression analysis validates the hypotheses, showcasing the impact of e-waste generation rates, recycling rates, and composition on e-waste recycling sustainability. The quantitative methodology employed unveils the intricate relationships, their strengths, and significance levels, contributing to a richer comprehension of e-waste management dynamics in Asia.

“…Due to the advantages of high energy density, long cycle life, high safety and low self‐discharge, lithium‐ion batteries (LIBs) have become very important energy storage devices and are widely used in mobile phones, computers, power tools, electric vehicles and other electronic devices [12,13] . However, the low theoretical capacity (372 mAh g −1 ) of existing commercially available graphite anode materials cannot meet the demand for higher power and energy density in the field of energy storage, and it is necessary to search for alternative anode materials with high capacity and long cycling stability to develop lithium‐ion batteries with better performance [14] .…”

Iron phosphide (FeP) is a promising electrochemical energy storage material due to easy to obtain and high theoretical capacity. However, the intrinsic poor conductivity and the large volume change during charging and discharging process, result in a sharp decline in capacity and short cycle life for FeP. In this work, the FeP/C/CNT nanocomposite was synthesized efficiently and conveniently by one‐step solid‐phase synthesis method. Amorphous carbon‐coated FeP particles are embedded in a three‐dimensional network structure composed of highly conductive carbon nanotubes, drastically enhancing the conductivity of FeP and reducing the volume expansion during charging and discharging. In the three‐electrode system, the FeP/C/CNT composites showed good electrochemical performance, with a specific capacity as high as 124.4 mAh g−1 at 1 A g−1. Meanwhile, the constructed Ni2P@C/CNT//FeP/C/CNT asymmetric supercapacitor delivered a high energy density (70.73 Wh kg−1), power density (7.9 kW kg−1) and a long cycle life (10000 cycles). In addition, as served as an anode material in the lithium ion battery, the FeP/C/CNT composite also displayed as high as 601.8 mAh g−1of specific capacity at 0.1 A g−1 and a good cycle stability, showing superior electrochemical performance. The above work provides a promising composite material for supercapacitors and lithium ion batteries. Moreover, the solid‐state preparation methods can provide a reference for the synthesis of transition metal phosphides.

“…At present, the traditional recycling methods of waste ion batteries are mainly pyrometallurgy and hydrometallurgy. − The pyrometallurgical process requires high energy consumption and produces toxic and highly corrosive gases, while hydrometallurgy requires more complex processes and secondary pollution treatment. Conventional metallurgical methods always destroy the structure of spent active materials and, by nature, require additional energy consumption to destroy the electrode structure. , The inherent shortcomings of traditional recycling methods determine their insufficiency in terms of sustainability, thus driving research related to the sustainable recycling of spent LIBs. Direct regeneration is another closed-loop process that is quite different from conventional metallurgical processes. , The direct regeneration process restores the properties of spent cathode materials in a nondestructive way, in the sense that it is more economical to repair defects in the surface and body based on its original compound structure.…”

In the context of resource utilization of spent lithium-ion batteries (LIBs), low-temperature plasma modification has the advantages of high efficiency and nonpollution over traditional recycling pathways. In this work, the technique of degrading the binder in electrode materials with low-temperature plasma is proposed to solve issues of poor direct flotation performance of anode and cathode materials and a low recovery rate. First, the analysis of contact angle measurement is carried out; second, the effect of low-temperature plasma on the difference of hydrophobicity of anode and cathode materials is verified by the results of particle-bubble adhesion, the recovery, and kinetics of single mineral flotation tests; finally, the mechanism of low-temperature plasma surface modification of exfoliated electrode materials is further characterized by X-ray diffraction, scanning electron microscope, and energy-dispersive X-ray spectroscopy, Fourier transform infrared, and X-ray photoelectron spectroscopy. Results show that low-temperature plasma oxidizes and degrades the binder through high-energy particles with the generated strong oxidizing active substances (•OH, •O, O3, etc.), making the original surface of anode and cathode materials exposed, which in turn increases the difference of hydrophobicity between the two and improves the flotation separation performance.
