Abstract Scope |
Lithium-ion batteries have been widely used as power sources for portable electronic applications such as electric vehicles (EVs) and energy storage systems (ESSs). However, the high cost of the cathode materials for lithium-ion batteries is an issue. Cathode materials account for more than 40% of the cost for a complete battery. The high battery cost is a chief obstacle to the widespread use of lithium-ion batteries. In this study, a method of recovering lithium resources from a waste Ni-rich cathode active material using a heat treatment in an inert gas atmosphere was proposed. XRD (x-ray diffraction) were used to investigate the lithium desorption and structural change in the cathode materials. SEM (scanning electron microscope) and ICP (inductively coupled plasma) were used to characterize their microstructure and composition. |
