Substituting the ramsdellite compound Li2Ti3O7 has been considered in order to improve the structure stability and performances for its use as electrode material for Li-ion accumulators. Two substitutions have been carried out, Ti/Fe and (Ti, Li)/(Fe,Ni). The presence of 57Fe as a local Mössbauer probe is interesting for studying its local environment and the electrochemical mechanisms induced by lithium insertion.
