A method is described to prepare a cathode material for high energy density rechargeable lithium ion batteries based on H 2 V 3 O 8 with improved cycling stability by means of a surface modification produced at low temperature in aqueous media. The battery comprises a stack composed by an anode, an electrolytic layer, a separator and a cathode, whose material is based on a mixture of carbon black Li x H 2-x V 3 O 8 modified by an aluminum hydroxide coating achieved in a one pot multistep reaction using aluminum in an amount comprised between 0.5 wt % and 10 wt %. |
