TL;DR: In this paper, the authors examined technologies and research efforts in battery recycling from the perspective of economic viability and life cycle inventory, and comments on the challenges facing battery recycling, and the role of battery design and circular economy in the sustainable development of battery industry where governments, manufacturers and consumers all play a part.

TL;DR: A novel process for extracting transition metals, recovering lithium and regenerating cathode materials based on facile co-extraction and co-precipitation processes has been developed and a waste battery management model is introduced to guarantee the material supply for spent battery recycling.

TL;DR: In this paper, a process based on reducing thermal treatment before acid leaching for the recovery of valuable materials from spent lithium-ion batteries is developed, which significantly improves the clean separation of the active materials from the current collectors and the complete removal of the binder and carbonaceous conductor.

TL;DR: By this process, copper and lithium can be recovered and graphite can be regenerated, serving as a sustainable approach for the comprehensive utilization of anode material from spent lithium-ion battery.

TL;DR: A novel and efficient approach for stepwise recycling of valuable metals from Ni-rich cathode material is developed and 98% manganese and over 90% cobalt are co-extracted at pH = 5, 30 vol% PC88A and volume ratio of oil to water (O:A) = 2:1, while 100% nickel is separated from lithium under the optimum extraction conditions.
