To ensure the safety of subsequent processing steps, the individual batteries are discharged using a constant potential discharge device, which reduces the voltage to a range between 1.50 and 2.75 V.
Therefore, during discharging, the inner battery components should not come into contact with the external steel casing, making the entire discharge process safe as the leakage and reaction of the internal electrolyte with air and water to generate toxic gases are avoided .
[ 45] For the first time, the self-discharge of rechargeable batteries induced by parasitic reactions is elucidated from the sight of the Evans Diagram, which is an effective method used in corrosion science for analyzing the coupled relationship between kinetics and thermodynamics.
Therefore, spent LIBs should be discharged to avoid these safety risks . To avoid the safety risks of battery disassembly, the state-of-charge should preferably be less than 2 % and optimally be below 0 % (corresponding to a voltage below 2 V).
Therefore, the effect of voltage rebound was also studied, and the obtained results showed that the voltage was over-discharged after flake-graphite discharge, which would cause irreversible damage to the anode material of the batteries and lead to battery failure. This is of great significance for the discharge pretreatment of spent LIBs.
The safest and most effective solution is to connect resistors at both ends of the battery to consume the residual electric energy of the spent LIBs. However, due to different battery sizes, this method is not economically feasible. Based on this principle, two feasible methods have been derived for discharge pretreatment.
