10. Hydrometallurgical process
 Recovery of pure metals from active
material
 High job creation as processes
involved are labour intensive.
 Recovery rate is high
 Final residue is low.
 Low gas emission.
Pyrometallurgical process
 Recovery of transition metals like
Co, Ni etc.
 Huge investment capital and low job
creation.
 Recovery rate is low.
 Final residue is high.
 High gas emission.

15. Optimization and selection of batteries
22/09/201615/19
 To maximize the capacity:
Uniform distribution of
energy in each cells
Reducing charging current
Prevent localized under
charging and over charging
Batteries are
selected after
performing ‘self
discharge test’
