The work describes the construction of lithium-ion batteries, with particular emphasis on metals that can be obtained as secondary raw materials. presents latest trends in recycling using pyro- and hydrometallurgical methods, or their combination. ecological aspect impact processes environment is shown, well challenges expectations for future field processes.

The Cover Feature illustrates the problems arising from finite lifetime of a battery and challenge to reanimate it for second life by means recycling process. It shows that dead solid-state batteries could be resurrected after digging them out their graves subsequent via hydrometallurgical process using citric acid.
