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.
In this paper, a novel anode architecture for Li-ion batteries fabricated by encapsulation of ZnO nanoparticles in the hollow core of glassy carbon–reduced graphene oxide electrospun composite nanofibers, is described.
