Rechargeable lithium batteries based on Li1 + xV3O8 thin films

Low-temperature thin films of Li1 + xV3O8 have been fabricated and tested in LiClO4/propylene carbonate-1,2-dimethoxyethane/Li cells. These cells show very good intercalation kinetics, and at 0.4 C discharge rate produce a specific energy of ≈ 110 Wh/kg. The films could be used in microbatteries for electronic devices, and applications requiring more power could also be envisaged.
