Özet
Intimately mixed MnO/Ni hybrid materials are synthesized using a two-step process; Pechini process
followed by a high temperature reduction step. As-prepared materials were characterized by X-ray
diffraction, transmission electron microscopy and electrochemical tests. (MnO)1-x/(Ni)x hybrid
materials with x=0, 0.2 and 0.5 mole ratios are electrochemically evaluated as anode materials for
lithium-ion batteries. The battery tests conclusively show that the coulombic efficiency, capacity
utilization factor, percentage capacity retention and high rate performance values of control MnO
material are enhanced with the presence of nearby metallic Ni nanoparticles. Oxide/metal hybrid
material could be a cheaper alternative to commonly known oxide/graphene system.
