Abstract

original image

Knowledge cluster: Spinel LiCo0.7Mn1.3O4 nanowire clusters, with each nanowire having a diameter of ca. 100 nm, result from a hydrothermal reaction between LiOH and Co0.35Mn0.65O2, obtained from K-birnessite at 150 °C. The nanowires demonstrate a good cycling stability and rate capability (improved by more than 50 %, compared to the bulk counterpart) in spite of their higher electrode density (3.4 g mL−1) over a wide voltage range, between 4.7 V and 2 V.
