Lithium ion batteries have been extensively used in portable electronic devices due to their high energy density and long cycle life. Recently, lithium ion batteries are required to run conditions that drive up to 1.5C, 2.0C, or higher in order to produce quick charge secondary cells, but the life degradation and safety concerns and rising. In other words, as the number of repetitions of the charge and discharge increases, the binding between the active materials and the ionic conductors becomes loose, and the contact resistance between the particles increases, and due to the increased resistance of the electrode, the battery performance is degraded, and during the life cycle degradation of cathode and anode materials occurs, and it is directly linked to life and safety issues. This study aims to improve the quick charge performance by improving the lithium ion material.
