Abstract

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.
