Zusammenfassung:This work focused on engineering the hybrid nanocomposite-based anode comprising CuFe2O4 (CFO), reduced graphene oxide (RG), and functionalized carbon nanotubes (FC) to investigate its Li-ion storage kinetics. The ternary nanocomposites CFO/RG/FC (CFO-C) demonstrated a specific capacity (SC) of 760 mAh/g at a Cdensity of 200 mA/g after 100 electrochemical charge-discharge cycles and an SC of 450 mAh/g at a high Cdensity of 500 mA/g after 300 electrochemical cycles. Results revealed that the addition of RG and FC aided in enhancing the electrical transport at the interface, in turn, it assisted in augmenting the Li-ion storage capability from ∼240 to ∼760 mAh/g at the end of 100 charge-discharge cycles with a Cdensity of 200 mA/g. RG and FC acted as anchoring sites for CFO and spacer, respectively, which resulted in improved electrical transport to accelerate Li-ion diffusion transport by fivefold. Such composite anode is a probable candidate as the high-performance anode in designing high-energy density Li-ion battery applications.
