Methodology & Scope

This review of “chemical stabilisation techniques made use of in literature” searched virtual scientific literature databases with Google Scholar using the keyword phase, “LIB discharging recycling”, with “LIB” also replaced with “lithium-ion battery”. The search results were then screened to find articles that referred to chemical stabilisation techniques for LIBs prior to dismantling or recycling. In many instances, this reference to stabilisation was a single sentence referring to how the LIBs were prepared for the investigation being conducted. However, there were also several articles in which there was a substantial study on the chemical stabilisation process. The articles that made use of chemical stabilisation techniques are described in Section 3 of this study. Many stabilisation processes were only published in patents and not in academic literature due to the high economic importance of recycling business models (Piątek, et al., 2020; Sommerville, et al., 2020). There are also little data available on the stabilisation techniques used in industrial battery recycling processes. Information on the composition of the discharge solution utilised, the time allowed for stabilisation, or the results of the stabilisation are not readily available for these industrial processes in comparison to the data that are available for processes described for research activities.
