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 hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) applications. Under these auspices, The battery technology group at 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 Li_1+x(Ni_1/3Co_1/3Mn_1/3)_1-xO₂/graphite will be discussed. The role of functional electrolyte additive and redox shuttle on battery performance, life and safety will be presented.
