In collaboration with L. Croguennec from ICMB Bordeaux, we are heavily investigating phosphate-besed Tavorite-type materials such as LiVPO4F and LiVPO4O which we believe possess very attractive properties as positive electrodes in Li batteries. They offer, additionnally, a wonderful crystal chemistry tool kit for understanding the vanadium redox chemistry. LiVPO4F, a material first proposed by J. Barker & co-workers, may be either reduced (at 1.80 V vs. Li) or oxidized (at 4.25 V vs. Li) and may be used, hence as both positive and negative electrodes in symmetrical cells. LiVPO4O may be either reduced (through 3 reduction processes) at ~2.20 V vs. Li or oxidized (at 3.95 V vs. Li). All the phases formed via Li+ insertion or extraction possess very interesting structural properties, with vanadyl-type bondings along more or less distorted corner sharing octahedra connected in 1-D chains.
