Abstract

Abstract : Nowadays the energy storage challenge is to develop a low cost, ecofriendly, high energy density material, showing a reversible capacity higher than 250 mA h g −1 . Abstract : Nowadays the energy storage challenge is to develop a low cost, ecofriendly, high energy density material, showing a reversible capacity higher than 250 mA h g −1 . We demonstrate that the first oxidation process of the nanostructured well-known Li2 MnO3 material leads to the formation of a completely disordered material. Then, in situ formation of a manganese-based oxide with a disordered rock salt structure leads to a stable electrode material showing a reversible capacity of 290 mA h g −1 .
