Advanced High Power and High Energy Systems for HEV and PHEV Applications

In its goal of developing more fuel efficient vehicles, the US Department of Energy in collaboration with the US auto industries are focusing on high-power and high energy lithium-ion batteries to meet the energy storage requirements for HEVs and PHEVs. Under these auspices, Argonne National Laboratory is investigating several different lithium ion chemistries in order to address the calendar life, cost and safety of high power and high energy lithium ion batteries for transportation applications. Several high power and high energy system based on nano-Li4Ti5O12/ LiMn2O4, and Li1+x(Ni1/3Co1/3Mn1/3)1-xO2 /graphite will be discussed. The role of functional electrolyte additive and redox shutlle on battery performance, life and safety will be presented.
