Документ Recycling and disposal of lithium-ion batteries(2024) Zinkevych, Petro; Baliuta, Serhii; Kuievda, IuliiaThe number of lithium-ion batteries (LIBs) is steadily increasing to meet the ever-increasing demand for sustainable energy and improved human quality of life. However, this growth is accompanied by a significant amount of LIB waste, which, if not properly disposed of, poses a safety and environmental threat due to its toxic content. In addition, the high consumption of scarce resources of precious metals, which are essential for the production of batteries, is also a serious problem. Due to the serious environmental, resource, safety and recycling issues, the recycling of used LIBs is extremely important to achieve sustainable development. Therefore, this review analyzes the importance and necessity of recycling spent LIBs from different resource and environmental perspectives. Next, a general overview of existing technologies for the recovery and recycling of spent LIBs, such as pyrometallurgy, hydrometallurgy, and mechanical method, is presented. In addition, the advantages and disadvantages of the described methods are analyzed. The factories of the world in which LIB processing is carried out are considered separately.Документ Determination of food additive zinc-cobalt(II) phosphate form resistant to high temperatures(2023) Antraptseva, Nadiia; Podobiy, Olena; Bila, GalinaThe aim of the research was to study the process of dehydration of zinc-cobalt(II) phosphates during heat treatment. Zinc-cobalt(II) phosphate tetrahydrates were used as the main research objects. The content of ingredients in the composition of phosphates was as follows, % mass.: Zn, 41.8–23.5; Co, 2.3–12.8; P, 13.6–13.8; H2O, 16.1–16.3. Spectral methods were used to study the process and products of dehydration. Infrared absorption spectra were recorded at 20 ℃ and –190 ℃, as well as in the process of heating phosphates. X-ray phase analysis was performed.
