N2 - LiCoO2/SrLi2Ti6O14 Li-ion rechargeable batteries with ∼6 Ah capacities are designed and assembled for use in hybrid electric vehicle (HEV) applications. For comparison, LiCoO 2/Li4Ti5O12 batteries are also constructed using similar processing parameters. Power tests are carried out using the hybrid pulse power characterization (HPPC) method. Experimental results show that the LiCoO2/SrLi2Ti6O 14 batteries have better power performance and more stable charge/discharge direct current (DC) resistances compared with the LiCoO 2/Li4Ti5O12 batteries. At a 50% depth of discharge (DOD), LiCoO2/SrLi2Ti6O 14 batteries have an excellent specific charge power density of 3973 W kg-1, which can be attributed to the high Li diffusion capability and high electronic conductivity of the SrLi2Ti6O 14 material.
