As the global consumption of lithium-ion batteries
(LIBs) continues to increase, it is important
15
to advance recycling technologies for spent LIBs
(S-LIBs). The main objective of this study is
16
to evaluate four pretreatment options for S-LIBs,
focusing on discharging, binder removal and
17
grinding methods from technical, environmental and
economic perspectives. The results show
18
that cryogenic discharging combined with cryogenic
grinding without solvent treatment offers
19
a good balance between process efficiency and ease
of implementation. Life cycle assessment
20
(LCA) showed that the use of NaCl solution for discharge has the lowest
global warming
21
potential but poses operational and safety
challenges. Conversely, options utilizing N-methyl-
22
2-pyrrolidone (NMP) for binder removal
increased both cost and environmental impact. The
23
economic analysis highlighted the critical need to optimize liquid nitrogen
and solvent usage
24
for scalability. These results provide insight into
sustainable and cost-effective pretreatment
25
strategies that improve the feasibility of
industrial-scale S-LIB recycling.
