Origin of Capacity Fading for Nano-grains Based Electrodes of Li Rechargeable Batteries

1 Results Li1+xV3O8,has been extensively investigated as a positive electrode material for lithium metal polymer batteries and a great deal of interest has been focused on the structural characterization and cyclability of this compound[1-6].From the present work,Li1.1V3O8 nanograins synthesized at low temperature from original two component gel precursor suffer from strong capacity fading on cycling.The latter is characterized by emergence of polarized redox processes at the expense of initial ones.Fro...
