“…[281,282] Several publications have indicated that better separation of material streams at the beginning of recycling can lead to higher product purity and recycling efficiency, contributing to a more competitive battery recycling industry. [281][282][283][284] Recently, Thompson et al evaluated the recycling costs for ten hydrometallurgical recycling processes from the literature and found that recycling based on shredded starting material offered cost savings of <20% for battery production compared to using virgin materials. In comparison, recycling processes based on disassembled batteries as starting material showed cost savings of 40-80%, without considering additional disassembly costs.…”

Being successfully introduced into the market only 30 years ago, lithium‐ion batteries have become state‐of‐the‐art power sources for portable electronic devices and the most promising candidate for energy storage in stationary or electric vehicle applications. This widespread use in a multitude of industrial and private applications leads to the need for recycling and reutilization of their constituent components. Improving the “recycling technology” of lithium ion batteries is a continuous effort and recycling is far from maturity today. The complexity of lithium ion batteries with varying active and inactive material chemistries interferes with the desire to establish one robust recycling procedure for all kinds of lithium ion batteries. Therefore, the current state of the art needs to be analyzed, improved, and adapted for the coming cell chemistries and components. This paper provides an overview of regulations and new battery directive demands. It covers current practices in material collection, sorting, transportation, handling, and recycling. Future generations of batteries will further increase the diversity of cell chemistry and components. Therefore, this paper presents predictions related to the challenges of future battery recycling with regard to battery materials and chemical composition, and discusses future approaches to battery recycling.

“…Automated disassembly is being investigated for the liberation of electrode materials on an industrial scale to avoid contamination between electrode materials, current collectors and other battery substances. Because of the growth of EVs, manual disassembly will likely become less significant and consequently, potential for optimization in battery disassembly has been cited in several studies ( Li et al., 2019a ; Markowski et al., 2014 ; Wegener et al., 2015 ; Kay et al., 2019 ; Glöser-Chahoud et al., 2021 ). Automatic battery disassembly makes recycling of batteries potentially safer and more economically viable.…”

“…The rapid growth in the market for electric vehicles around the world is essential, and requires the efficient management of obsolete lithium-ion battery packs after completing their service life. According to the work in [1], industrial disassembling is a key enabler of circular economy solutions for obsolete electric vehicle battery systems. However, currently, the battery packs disassembly is primarily accomplished by humans with a fixed robotassisted battery disassembly workstation.…”

Currently, there is no domain dictionary in the field of electric vehicles disassembly and other domain dictionary construction algorithms do not accurately extract terminology from disassembly text, because the terminology is complex and variable. Herein, the construction of a domain dictionary for the disassembly of electric vehicles is a research work that has important research significance. Extracting high-quality keywords from text and categorizing them widely uses information mining, which is the basis of named entity recognition, relation extraction, knowledge questions and answers and other disassembly domain information recognition and extraction. In this paper, we propose a supervised learning dictionary construction algorithm based on multi-dimensional features that combines different features of extraction candidate keywords from the text of each scientific study. Keywords recognition is regarded as a binary classification problem using the LightGBM model to filter each keyword, and then expand the domain dictionary based on the pointwise mutual information value between keywords and its category. Here, we make use of Chinese disassembly manuals, patents and papers in order to establish a general corpus about the disassembly information and then use our model to mine the disassembly parts, disassembly tools, disassembly methods, disassembly process, and other categories of disassembly keywords. The experiment evidenced that our algorithms can significantly improve extraction and category performance better than traditional algorithms in the disassembly domain. We also investigated the performance algorithms and attempts to describe them. Our work sets a benchmark for domain dictionary construction in the field of disassembly of electric vehicles that is based on the newly developed dataset using a multi-class terminology classification.
