Exploration of MnFeO<sub>3</sub>/Multiwalled Carbon Nanotubes Composite as Potential Anode for Lithium Ion Batteries
MnFeO<sub>3</sub>, investigated for its application in sensors, catalysis,
and semiconductors, was explored for the first time as anode for lithium
ion batteries in the form of MnFeO<sub>3</sub>/multiwalled carbon
nanotubes (MWCNT) composite. A scalable and highly reproducible sonochemical
process was adopted to form the composite, wherein the interweaved
MWCNT ensures better electronic conductivity and pinning of pristine
MnFeO<sub>3</sub> particles with a conductive coating. MnFeO<sub>3</sub>/MWCNT composite anode exhibits superior electrochemical properties
than pristine MnFeO<sub>3</sub> anode in such a manner that a steady-state
reversible capacity of 840 mAh g<sup>–1</sup> was obtained
at 0.5 A g<sup>–1</sup> even after 50 cycles against an inferior
capacity of 200 mAh g<sup>–1</sup> offered by MnFeO<sub>3</sub>. Further, MnFeO<sub>3</sub>/MWCNT composite anode shows excellent
rate capability and reversibility by way of delivering appreciable
capacity values of 2960 and 410 mAh g<sup>–1</sup> at 0.5 and
10 A g<sup>–1</sup>, respectively. These results suggest that
the currently synthesized MnFeO<sub>3</sub>/MWCNT nanocomposite anode
could be considered as a promising candidate for next-generation hybrid
energy storage applications. The study is bestowed with the identification
and demonstration of earth-abundant, environment-friendly, and low-cost
metals, specifically, Mn- and Fe-based composite anodes for high capacity
and high rate lithium ion battery applications, which is noteworthy
