Batteries are a major technological challenge in this new century, as they stand as a key way to make a more efficient use of energy. Rechargeable Li-ion batteries, by having the highest energy density of any such device, have emerged as the technology of choice for powering electric vehicles and show great promises for grid applications. For such promises to materialize fully, the quest for new positive electrode materials showing safety, sustainability and cost advantages must continue. Here, progresses have been recently achieved with the arrival of polyanionic compounds. Among them, LiFePO4 is the most attractive, although its energy density is penalized by the low redox voltage (3.45 V vs Li+/Li0) of the Fe3+/Fe2+ redox couple.
