To face increasing needs in batteries demand for hybrid & electric vehicles, both high energy and high power Li-ion cells are under development. To increase the battery autonomy, several active materials are on improvement. On the other side, to enable fast charging and sustain high currents for power systems, high capacity retention with high stability materials in innovative design is developed. Introducing new technologies also requires respecting safety behavior, affordable cost and environmental aware. In this paper, we will introduce our state of the art regarding lithium iron phosphate chemistry developed for the first generation of electric vehicles batteries or for micro hybrid electric vehicles when coupled with lithium titanate. More over, we will present our latest results on new high energy negative (Si-Carbon composite) and positive electrodes (Li-Rich Lamellar Oxides or "5V" Spinel oxide) developed to replace current negative (Graphite) and positive (layered cobalt oxides, manganese based or iron phosphate based) materials in cells for batteries of 2nd generation.
