В связи с постоянно растущей потребностью в литийионных аккумуляторах (ЛИА) и увеличением количества уже используемых накопительных устройств актуальной темой на сегодняшний день является создание экологичного, безопасного и дешевого способа их утилизации. Жизненный цикл литийионных аккумуляторов меньше, чем оборудования, где они применяются, поэтому возрастает риск образования большого количества отходов, которые могут привести к серьезным проблемам с утилизацией и пагубному воздействию на окружающую среду. В то же время отработанные литийионные аккумуляторы можно использовать вторично, извлекая из них ценные компоненты для возвращения в производственный цикл. В связи с этим целью данной работы является исследование методов утилизации литийионных аккумуляторов и анализ предложенного авторами способа их утилизации с извлечением ценных компонентов (Li2CO3) при внедрении принципов экономики замкнутого цикла в производство.Материалы и методы. Авторами использовались методы систематизации научной литературы по проблематике утилизации литийионных аккумуляторов. Для выбора наиболее перспективного из них была использована программа Mpr_Dipl. В ней заложены прямые методы принятия решений, метод парных сравнений и метод взвешенной суммы. Разработка технологической схемы процесса переработки ЛИА проводилась в программе «КОМПАС-3D».Результаты исследования. В результате анализа были выделены достоинства и недостатки каждого метода утилизации литийионных аккумуляторов, а также выбран гидрохимический способ с использованием методики решения задач с многокритериальным выбором. Предложена технологическая схема процесса переработки литийионных аккумуляторов с извлечением карбоната лития, состоящая из пяти стадий: измельчение, разделение, фильтрация, осаждение и вылавливание влажного осадка Li2CO3. Рассчитан материальный баланс разработанного способа утилизации.Обсуждение и заключение. Разработанная авторами система утилизации обеспечивает безопасную переработку отработавших литийионных аккумуляторов при минимальном негативном воздействии на окружающую среду и максимальном выделении ценных компонентов. Результаты исследования могут быть использованы для модернизации процесса утилизации литийионных аккумуляторов с целью извлечения дополнительной прибыли от продажи карбоната лития.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Due to the increasing demand for lithium-ion batteries, it has become a pressing issue to find an environmentally friendly and safe way to dispose of old batteries. The life cycle of these batteries is shorter than that of the equipment they power, which leads to a growing amount of waste. This waste poses a serious problem for disposal and can have harmful effects on the environment. At the same time, recycling spent lithium-ion batteries offers a solution. By extracting valuable components we can return these components to the production process and create a closed-loop system. In this regard, the aim of this study is to investigate the methods of recycling lithium-ion batteries and to analyze the proposed method for their disposal, which involves extracting valuable components such as Li2CO3, while introducing the principles of a closed-loop economy into the production process.Materials and Methods. The methods of systematizing scientific literature on lithium-ion battery recycling were used. The “Mpr_Dipl” software was used to select the most promising method, which includes direct decision-making, paired comparison, and weighted sum methods. A technological process for lithium-ion batteries processing was developed using the COMPASS-3D software.Results. As a result of the analysis, the advantages and disadvantages of each lithium-ion recycling method were highlighted. A hydrochemical method was selected using the multi-criteria decision-making method. A five-stage process for lithium ion battery processing with lithium carbonate extraction was developed, including grinding, separation, filtration, precipitation, and wet Li2CO3 capture. The material balance for the developed method was calculated.Discussion and Conclusion. The developed recycling system ensures safe recycling of used lithium-ion batteries with minimal negative environmental impact and maximum recovery of valuable components. These results can be used to optimize the recycling process and maximize the extraction of valuable materials from spent lithium-ion batteries for further sale as lithium carbonate, thereby generating additional revenue</p></trans-abstract><kwd-group xml:lang="ru"><kwd>литий-ионный аккумулятор</kwd><kwd>переработка</kwd><kwd>утилизация</kwd><kwd>экономика замкнутого цикла</kwd><kwd>гидрометаллургия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lithium-ion battery</kwd><kwd>recycling</kwd><kwd>disposal</kwd><kwd>circular economy</kwd><kwd>hydrometallurgy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bin Huang, Zhefei Pan, Xiangyu Su, Liang An.
