Knowledge cluster: Spinel LiCo 0.7 Mn 1.3 O 4 nanowire clusters, with each nanowire having a diameter of ca. 100 nm, result from a hydrothermal reaction between LiOH and Co 0.35 Mn 0.65 O 2 , 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.
