N2 - In this study, one-dimensional Li0.33MnO2 nanorods were synthesized by a solid state reaction using γ-MnO2 as a precursor. γ-MnO2 was prepared under different reaction times by a redox process. The HR-TEM results showed that the diameter and length of the Li0.33MnO2 nanorods are 5-20 nm and about 200 nm, respectively. The Li0.33MnO2 nanorods delivered a discharge capacity of 157 mA h g-1 at 1 C, and retained 97% of their initial capacity over 30 cycles. Good rate performance was also observed, with discharge capacities of 201 and 133 mA h g-1 at 0.1 C and 2 C, respectively. The morphology of the nanorods could increase their electrochemical properties, resulting in higher capacity and rate performance.
