In this work, Li4Ti5O12 has been used as an anode material in lithium-ion batteries for electricity storage applications, which operate under intermittent cycling conditions with higher charge/discharge rates than 4C (i.e., current extracting the full capacity of battery in 15 min). Li4Ti5O12/LiCoO2-LiNi1-x-yCoxAlyO2 full cells have been designed and constructed with different cell parameters (N/P ratio, electrode dimension, materials loading level, etc.), and then the effect of design parameters on the capacity, cycle life and charge/discharge behavior has been analyzed using various physical and electrochemical techniques.
