The fluorine-modified Li[Ni0.73Co0.12Mn0.15]O2−xFx materials exhibit superior cycling stability, which is attributed to the synergistic protection of the surface NiO-like phase and fluoride layer.
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.
