ZnMn2O4 nanoparticles synthesized by a hydrothermal method as an anode material for Li-ion batteries

Abstract ZnMn 2 O 4 nanoparticles prepared by a hydrothermal synthesis were evaluated as anode material for Li-ion batteries. XRD measurements showed that a ZnMn 2 O 4 I4 1 /amd tetragonal spinel structure was obtained with crystallite sizes ≤5 nm. TEM micrographs showed that particles of about 5 nm in diameter were synthesized. Li/ZnMn 2 O 4 half cell battery cycling showed that the nanoparticles, using lithium salt of carboxymethylcellulose as binder, give a high capacity of 430 mAh g −1 when cycled 100 times at C /10.
