Lithium-ion batteries are commercially important devices that provide low-carbon energy storage solutions for multiple industries. At the end of their service life, recovering their materials improves the sustainability of resources, and a paper published in Materials Proceedings has explored the recovery of graphite from lithium-ion batteries.

The Growth of Lithium-Ion Batteries
The global shift toward carbon neutrality and away from reliance on fossil fuels is gathering pace. Recent international agreements such as COP26 have crystallized the need to significantly scale back processes and technologies that emit carbon dioxide and implement technologies that can fill the gap in energy harvesting and storage.
Lithium-ion batteries have emerged as forerunners in technological development and the sector is predicted to grow due to the demand of the transport industry for low-emissions and zero-emissions vehicles. The market is predicted to display a compound annual growth rate between 2020 and 2026 of 15%.
The global electric vehicle market is predicted to grow by 47% in the same period. According to a report by IMARC Group, the electric vehicle industry shipped 2.45 million units globally in 2020.
Waste and Recyclability Issues
However, with the growth in the electric vehicle and lithium-ion battery industries comes an age-old...
