摘要： ► We have prepared an ordered spinel LiNi0.5Mn1.5O4 nanorods (LNMO-NRs). ► The LNMO-NRs show pure P4332 phase with a uniform one dimensional nanostructure. ► The discharge capacity of the as-prepared LNMO-NRs approached 135mAhg−1 at 1C. ► The LNMO-NRs exhibited a superior high-rate capability (120mAhg−1 at 20C). We report on the synthesis of ordered spinel LiNi0.5Mn1.5O4 nanorods (LNMO-NRs) and their application as high-rate cathode materials of lithium-ion batteries. Ordered spinel LNMO-NRs were prepared by a simple self-support template method followed by a solid-state reaction. The as prepared LNMO-NRs displayed uniform one dimensional (1D) nanostructure with the diameters of about 100nm and the lengths around 2–3μm. X-ray diffraction and Raman spectroscopy showed that the products existed in pure P4332 phase. When the as-prepared LNMO-NRs were applied as the cathode materials for lithium ion batteries, they exhibited a superior high-rate capability (135mAhg−1 at 1C, 120mAhg−1 at 20C) and a good cyclability (at 20C with a high retention of 90% after 80cycles). The durable high-rate capability was attributed to the one-dimensional nanostructure with the ordered phase that shows fast Li-intercalation kinetics and good structural stability. 出版者： Elsevier B.V 出版日期： 2013-01-01 出處： Journal of electroanalytical chemistry (Lausanne, Switzerland), 2013-01, Vol.688 (1), p.113-117 版權： 2012 Elsevier B.V. 識別號： ISSN: 1572-6657 識別號： EISSN: 1873-2569 識別號： DOI: 10.1016/j.jelechem.2012.09.042
