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.
Nanocrystalline Li(Ni1/3Co1/3Mn1/3)O2 (NCM) was successfully synthesized through a solution combustion route to use as the cathode material in a Li-ion battery.
