Abstract:
Abstract— The development of lithium-ion batteries (LIBs) for use in electric vehicles, portable electronic devices, and energy-
storage devices has resulted in an increase in the quantity of used LIBs. The environment and public health are seriously
endangered by the hazardous metals found in spent LIBs, for example Cobalt and Manganese metals, with a poisonous caustic
electrolyte, and binders of organic origin. Based on these factors, procedures for recycling LIBs that are efficient, affordable,
also benign to the environment are being developed in order to ensure a long-term sustainable future solution. In this research,
used lithium batteries, were released into a sodium chloride solution with a lower concentration, manual dismantling of LIBs
components, separations of components as cathode, anode, plastic casing, separators, electrolyte. Also dissolution of cathode
material in sodium hydroxide solutions and finally characterized the cathode electrode, using X-ray fluorescence spectrometer
(XRF) and Thermogravimetric analysis (TGA). The Polyvinylidene fluoride (PVDF) and diethyl carbonate (DEC) particles in
raw cathode material, detected by Fourier Transform infrared (FT-IR) analysis, were effectively thermally decomposed at
464.98 °C and 150 °C respectively. The XRF analysis of thermally treated cathode material powder showed presence of: 61.72
% of Co, 12.11 % of Ni, 9.64 % of Mn, and 16.53 % others component.
