ABSTRACT

Cobalt is a key element of the lithium-ion batteries that supply energy and continuous power to several electronic equipments such as cellphones, computers, and electric vehicles. Due to the depletion of primary sources of metal extraction and limited supply, countries are now focusing on recycling secondary resources for economic and sustainable management. Though the majority of the technologies involved are focused on industrial-scale development, they lack eco-friendliness and efficiency. The dead lithium-ion batteries containing several valuable metals such as cobalt, lithium, manganese and nickel are regarded as an appealing secondary resource. Battery recycling is required not only to reduce energy consumption but also to alleviate the scarcity of rare resources and eliminate pollution from hazardous components, as the world moves toward more sustainable industries such as consumer electronics and electric vehicles. The significance of cobalt recovery from secondary resources is emphasized in this paper. From the research, it is found that the amount of cobalt is more in the spent LIBs. Hence, focus is given on the green method of leaching of the spent Lithium-ion batteries (LIB) and extracting the valuable metals such as cobalt, nickel and lithium using organic acids. The method of using organic acids as leachant is environmentally friendly, cost-effective, and has the potential to provide sustainable development in the battery industry. This initiative is aimed to stimulate people’s interest in wasted LIBs recycling with organic acids and raise awareness of the benefits.

摘要

钴是锂离子电池的关键元素，锂离子电池为手机、电脑和电动汽车等多种电子设备提供能量和持续供电。由于金属提取的主要资源枯竭且供应有限，各国现在都将重点放在回收二次资源上以进行经济和可持续管理。尽管所涉及的大多数技术都集中在工业规模的开发上，但它们缺乏生态友好性和效率。含有钴、锂、锰和镍等多种贵重金属的废锂离子电池被视为极具吸引力的二次资源。电池回收不仅是为了降低能源消耗，也是为了缓解稀有资源的短缺，消除有害成分的污染，随着世界转向更具可持续性的行业，例如消费电子产品和电动汽车。本文强调了从二次资源中回收钴的意义。从研究中发现，废锂离子电池中钴的含量更多。因此，重点关注废旧锂离子电池（LIB）浸出和使用有机酸提取有价值金属（如钴、镍和锂）的绿色方法。使用有机酸作为浸出剂的方法环境友好、成本低，具有为电池行业提供可持续发展的潜力。该倡议旨在激发人们对用有机酸回收废锂离子电池的兴趣，并提高人们对这些好处的认识。本文强调了从二次资源中回收钴的意义。从研究中发现，废锂离子电池中钴的含量更多。因此，重点关注废旧锂离子电池（LIB）浸出和使用有机酸提取有价值金属（如钴、镍和锂）的绿色方法。使用有机酸作为浸出剂的方法环境友好、成本低，具有为电池行业提供可持续发展的潜力。该倡议旨在激发人们对用有机酸回收废锂离子电池的兴趣，并提高人们对这些好处的认识。本文强调了从二次资源中回收钴的意义。从研究中发现，废锂离子电池中钴的含量更多。因此，重点关注废旧锂离子电池（LIB）浸出和使用有机酸提取有价值金属（如钴、镍和锂）的绿色方法。使用有机酸作为浸出剂的方法环境友好、成本低，具有为电池行业提供可持续发展的潜力。该倡议旨在激发人们对用有机酸回收废锂离子电池的兴趣，并提高人们对这些好处的认识。重点介绍了用有机酸浸出废旧锂离子电池 (LIB) 并提取钴、镍和锂等有价金属的绿色方法。使用有机酸作为浸出剂的方法环境友好、成本低，具有为电池行业提供可持续发展的潜力。该倡议旨在激发人们对用有机酸回收废锂离子电池的兴趣，并提高人们对这些好处的认识。重点介绍了用有机酸浸出废旧锂离子电池 (LIB) 并提取钴、镍和锂等有价金属的绿色方法。使用有机酸作为浸出剂的方法环境友好、成本低，具有为电池行业提供可持续发展的潜力。该倡议旨在激发人们对用有机酸回收废锂离子电池的兴趣，并提高人们对这些好处的认识。
