A cathode material for rechargeable lithium batteries is one possible application for the birnessite‐related layered MnO 2 nanobelts (see Figure) reported here. A simple hydrothermal procedure is described that results in high‐purity, long (up to several tens of micrometers) nanobelts with narrow size dispersion (width 5–15 nm) that are usually self‐assembled into bundles.
