This survey is to review the advancement recorded so far in the lithium-ion battery recycling technologies in compliance with environmental laws. Amongst many of the technologies used to date, the best is the use of simple but scale-up dissolution technology involving non-toxic suitable organic solvents that can effectively dissolve toxic binder, PVdF in battery to avoid much pollution. Pollution through the hydrolysis of LiPF6 from the lithium-ion battery can also be minimized through conversion to useful compounds instead of using virgin materials for the synthesis. More environmentally friendly recycling technologies are still needed to meet the demands for materials, for scale-up processes and in compliance with environmental laws.
