The development of today's information-rich world relies on green technologies, with portable electronic devices playing a crucial role in information handling and communication. The widespread use of portable devices has made batteries an essential part of human life, increasing the demand for critical elements used in these devices. New approaches are being adopted to address supply challenges associated with metals used in portable electronic devices, with a focus on recovery and recycling efforts.
Today's information-rich world has become more flexible, and its development trusts upon green technologies. Due to rise in demand for proficient transmission of worldwide information and communication, a portable podium is required. Small electronic devices such as portable computers, mobile phones and other electronic devices serve as encouraging entrants that have endorsed the swift progression of information handling and allocation. Attributable to the increased use of portable electronic devices, the batteries have become closely associated with human life and hardly there will be an area without its application. The devices used for these purposes are made of critical elements which have matchless properties inimitable by other materials. Such metals are in high ultimatum and head-on supply insecurity because of several hurdles in recycling technologies. For handling the supply challenges associated with these metals, new approaches have been adopted to isolate these elements from secondary sources. The discarding of voluminous spent batteries has produced a compulsion to discover ways to recover and recycle metals that exist for the development of recycling facility. This report is envisioned to be an appreciated reference for providing state of art of hydrometallurgical and pyrometallurgical treatments for the management of spent nickel metal hydride and lithium-ion batteries. It has been revealed that efficient hydrometallurgical recycling techniques proved to be helpful in terms of environmental defence and maintenance of resources.
