Li1.2Ni0.2Mn0.6O2 with a stable network flake structure shows excellent rate capacities and cycling stability as a Li-ion battery cathode.
Spent LiFePO4 (LFP) cathodes were revived through a microwave-hydrothermal relithiation process, complemented with microwave-reduced graphene oxide (MWrGO) derived from spent graphite anodes, to form a composite LFP/MWrGO cathode material.
