Impressive capacity improvements can be obtained by wrapping insulating crystallites of Li3V2(PO4)3 within a conductive carbon web. The single crystal analysis (see Figure) and electrochemical characteristics of Li3V2(PO4)3 are reported. X-ray diffraction analysis of the single phases formed on Li extraction shows that the framework is maintained with a little loss of crystallinity; on re-insertion of Li, the Li3.0V2(PO4)3 framework is fully recrystallized.
