    In this talk I will present recent work exploring the use of metastable materials having the calcium ferrite structure as electrodes in Li-ion batteries. By using low temperature ion-exchange reactions it is possible to make Li-analogues of NaFeTiO4 and Na2Fe3SbO8 with Li-ions replacing Na in the one dimensional channels within the Fe-Ti/Sb-O polyhedral framework. The anomalous changes to the structure when Na is replaced with Li and possible origins of this will be discussed, as will the electrochemical properties of both the Li and Na materials. The divergence in the properties will be discussed in relation to the crystal structure and chemical properties of Na and Li ions.
