Mechanochemical upcycling of spent LiCoO2 to new LiNi0.80Co0.15Al0.05O2 battery: An atom economy strategy
Abstract
The rapid expansion of the electric vehicle market generates a large volume of spent lithium-ion batteries (LIBs). The employment of harsh chemicals and lack of atom economy in the recycling method leads to significantly more environmental pollution and CO2 emissions. Herein, Al foil wastes inherent in spent LIBs are used as the reducing agent and purifying agent in situ to induce the reduction of transition metal oxides and the targeted separation of impurity metals, and ultimately incorporated into the upcycled product at 100% atom efficiency.
