Battery recycling is an ideal solution to creating wealth from waste, yet the development of battery recycling technologies awaits considerable effort.
Taking the recycling of 1 kg of LiNi 1/3 Co 1/3 Mn 1/3 O 2 (NMC111) cathode as an example, direct recovery can save energy up to 50% and reduce gas emission by 85% . Meanwhile, the value of degraded electroactive materials is also retained to the maximum extent through a direct regeneration process .
Meanwhile, the value of degraded electroactive materials is also retained to the maximum extent through a direct regeneration process . For example, the total cost of pyrometallurgical, hydrometallurgical, and direct recycling of LMO batteries was estimated to be $2.43, $1.3, and $0.94 per kg of spent battery cells processed, respectively .
Shifting the open-loop manufacturing manner into a closed-loop fashion is the ultimate solution, leading to a need for battery recycling. However, in the pursuit of sustainably and effectively recycling spent LIBs, various battery components and associated rich chemistries undoubtedly pose serious challenges.
For the sake of the simplicity and understanding, the direct recovery strategies, developed for crystal structure rearrangement of three representative cathode materials, namely lithium cobalt oxide, layered lithium transition metal oxide, and lithium iron phosphate, are discussed in the following sections [88, 89]. 3.1.
The destruction and exfoliation of graphite occur during the repeated charging/discharging process because the repeated de-intercalation of Li ion leads to the volume change of graphite anode materials . The associated internal stress occurs on the graphite lattice.
