“…To deal with this problem, researchers have taken several measures, one is to reduce the amount of H 2 directly. Bhandari et al [52] explored selective recycling of Li salt and metallic values (Co, Ni, and Mn) from spent NMC batteries using pure hydrogen and mixed gas (10 % H 2 + 90 % Ar). The reduction mechanism of hydrogen on NMC cathode active powder is illustrated in Figure 6c.…”

The prosperity of the lithium‐ion battery market is inevitably accompanied by the depletion of corresponding resources and the accumulation of spent batteries in a dialectical manner. Spent lithium‐ion batteries are harboring the characteristics of hazardous waste and high‐value resources, so efficient recycling is of great significance. The cathode material is considered as an interesting target for repurposing. Despite some important reviews give commendable emphasis to recycling technologies, there is still a dearth of exploration of recycling mechanisms. This deficiency of awareness highlights the need for further research and development in this area. This review aims to systematically review and thoroughly discuss the reduction reaction mechanism of each method regarding different cathode materials. And systematically digest the selection of reducing agent and the effect of reduction reaction on material regeneration are systematically digested, as well as the impact of the reduction reaction on the regeneration of materials. This review emphasizes the importance of balancing efficiency, economic and environmental benefits in reuse technologies. Finally, the review proposes an outlook on the opportunities and challenges facing the reuse of key materials for next‐generation spent batteries aimed at promoting the green and sustainable development of lithium‐ion batteries, circular economy and ecological balance.

“…The reducing roasting method represents an advancement over conventional pyrometallurgy. Various carbon sources (such as biomass 18 ), reducing gases, 19 metals (such as aluminum), 20 and even separator materials found within the batteries themselves, 21 have been employed. The objective is to transform the transition metals in the exhausted cathode material into soluble substances, thereby enabling direct leaching with pure water.…”

“…При недостатке водорода процесс восстановления протекает не полностью [10]. Также водород применяется для восстановления катодных материалов в литий-ионных аккумуляторах [11] При обзоре способов очистки сопловых лопаток, представленных в работах [12; 13], восстановительные свойства водорода используются на одном из этапов очистки поверхности лопаток газотурбинного двигателя (ГТД) от оксидов металлов элементарным фтором [14; 15]. Способ заключается в очищении поврежденных металлических деталей из жаропрочного никелевого сплава, содержащих микротрещины и применяется для ремонта деталей путем пайки.…”

Currently, there is a growing interest in the use of hydrogen in the composition of fuel mixtures for turbojet engines and gas turbine units (GTU). The effect of hydrogen on heat-resistant nickel alloys of gas turbine blades has been little studied. In this regard, this work is devoted to studying the effect of hydrogen on nickel oxide reduction on the surface of the nozzle blade of a gas turbine engine. Hydrogen is a good reducing agent. Therefore, this article discusses the effects of hydrogen under various conditions with metal oxides, and methods of metal oxides reduction on the surface of the blades of a gas turbine engine. The thermodynamics of the interaction of aluminum, titanium, nickel and tungsten oxides with hydrogen fluoride and reactions of fluoride with hydrogen was investigated in the temperature range 273 – 1373 K. It was established that the interaction of aluminum oxide with hydrogen fluoride occurs in the temperature range from 273 to 1073 K, titanium oxide with hydrogen fluoride – from 273 to 373 K, nickel oxide with hydrogen fluoride – from 273 to 873 K. In this case, of the resulting fluorides, only nickel fluoride interacts with hydrogen at temperatures above 673 K. Hydrogen interacts with nickel oxide throughout the entire temperature range, and with tungsten oxide at temperatures above 1173 K. We studied the effect of hydrogen on heat-resistant nickel alloys of gas turbine blades subjected to preliminary fluorination and not treated with fluorine compounds. Nickel oxide reduction with hydrogen proceeds better after the preliminary fluorination process. In this case, particles 2 – 5 μm in size containing 90.16 % Ni are formed on the surface of the blade sample. Without fluorination, this process at 1223 K and duration of 1 h does not occur.
