تطوير طريقة ذات كلفة مالية قليلة و بيئية تؤمن رفع كفاءة فصل العناصر المعدنية الرئيسة من مخلفات بطاريات شوارد الليثيوم

الملخص EN

The use of lithium-ion battery technology spreads in electronic devices and its remanufacturing process is accompanied by a loss of used mineral elements at the End-of-Life without the development of an effective way to retrieve them and this is also accompanied by a decline on the environmental level.

Therefore, it is considered very important the development of technological methods such as waste recycling to recover the loss of elemental minerals and raise the efficiency of desirable element extraction before embarking on recycling and manufacturing of these products in terms of environmental and economic concerns.

In this paper, an economic-environmental simple, cheap and easy applicable method was developed based on reducing the consumption of materials and energy to increase the technological work efficiency.

The lithium-ion cathode batteries were collated, such as: LiCoO2, LiFePO4, LiMn2O4 and the Mixed-metal-matrix cathode, in the laboratories of Life Science Dept.

in Fac.

Dentistry, then cut, screened according to the sizes of the grains formed, and liberating their elemental contents.

Their concentrations were determined by XRF, such as cobalt, manganese, nickel, iron and copper, in order to achieve better separation yields and enhance the efficiency of subsequent recycling operations.

Thus, this paper exceptionally presents, in clear methodology the possible values for the recovery of minerals from lithium-ion batteries.

The results showed that the source of industrialization had no effects on metal distribution in batteries’ sorting fractions.

Recommendations were made to conduct the initial screening process, according to the type of cathode in addition to paste the key information concerning recycling on the cover of the battery, such as: the type of lithium-ion cathode batteries, elemental content of the final product, materials for manufacturing metal casing of the battery, and the producing factory.
