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.
