Effect of Mn3O4 nanoparticle composition and distribution on graphene as a potential hybrid anode material for lithium-ion batteries

Abstract

Nanosized manganese oxide (Mn₃O₄) particles grown on reduced graphene oxide (rGO) have been prepared via a facile synthetic method with different weight ratios, as hybrid anode materials for high performance lithium ion batteries (LIBs). The Mn₃O₄/rGO hybrid materials have been characterized by a library of techniques to better understand the effect of the structure and composition of the hybrids on the electrochemical performance of LIBs. The results show that the Mn₃O₄ nanoparticles are homogenously dispersed on rGO nanosheets. By virtue of efficient electron conduction pathways and high surface area properties promoted by rGOs, the Mn₃O₄/rGO hybrid material used as an anode material exhibits an enhanced reversible capacity, cycling stability, and rate capability.
