MgCl 2 ·6H 2 O–NaCl–KCl ternary molten salt-assisted mild-temperature reduction roasting of spent lithium-ion battery cathode materials
Xueshuai Zhu, Tingxiu Hao, Tao Liu, Ping FengA ternary MgCl 2 ·6H 2 O–NaCl–KCl molten salt enables efficient recycling of spent Li-ion battery cathodes at 500 °C using waste graphite, achieving >99% Li recovery with 75% less reductant.
