Synthetic paramontroseite VO_2 with good aqueous lithium-ion battery performance

摘要

Synthetic paramontroseite VO_2 has been successfully obtained using a simple chemical reaction route for the first time after fifty years; the paramontroseite phase shows a conducting property and good aqueous lithium ion battery performance.rnIn the 1950s, Mrose and Evans discovered a new mineral paramontroseite VO_2 from the Colorado Plateaus region. Paramontroseite vanadium dioxide (VO_2) possesses a regular tunnel form, in which the VO_6 octahedra are linked into double chains and the double chains link corners with each other in turn to form a framework having tunnels with rectangular-shaped cross sections that are 1×2 octahedra on a side. For more than fifty years, efforts have been strongly focused on the structural analysis of paramontroseite and the transformation relationship between paramontroseite and montroseite, owing to its fascinating tunnelled structure.
