Experimental recycling processes :
•Recycling processes of spent lithium-ion
batteries can be divided into hydrometallurgical
treatment and pyrometallurgical treatment, but
also include combinations of pyro- and
hydrometallurgical treatment .
•The high-temperature pyrometallurgical
treatment focuses on the formation of metal
alloys containing cobalt, nickel, copper and iron,
while lithium, aluminium and manganese
remain in the slage and can be used for
construction materials.
•Hydrometallurgical treatment uses chemical
leaching to material recovery in low
temperature and is more environment-
friendly due to its low operating temperature,
while also enabling high purity yield with high
lithium extraction efficiency.
Industrial recycling processes :
•Akkuser is a company running a recycling
plant located in Nivala, Finland, which was
opened in May 2006. Since the beginning of
their operation they recycle all the portable
batteries.
•The aim of this study was to investigate the
optimal leaching conditions for recovery of Co,
Mn, Li and Ni from spent lithium-ion batteries
• Leaching efficiency of Li 90%,Co 49%,Ni
94.6% and Mn 48.6% can be achived when the
cathodic material leached only in (1M)H2SO4
at 368K for 240 min.

•To Process spent lithium batteries to extarct
the metal’s.
•The leaching is carried out with Suitable
leaching agent.
•Leaching process take place in the presence
and absence of reductant.
•Leaching is an essential step for effective
recovery of metals from spent lithium-ion
batteries during suitable treatment
•Reducing agent : NaHSO3 & H2O2 .
Abstract
Introduction
•Rechargeble batteries have an essential role
in daily life.
•The global e-waste monitar classifies the e-
waste within the category “small IT and
telecommunication equipment “ with an
estimated generation of 3.9 m metric ton’s in
2016.
•In mobile phone, the battery represent’s
21.12wt% of total weight together with the
other material such as plastic material (25.75
wt%).
