Abstract

To investigate changes in characteristics based on the anode/cathode loading ratio of the Li4Ti5O12 battery, Li4Ti5O12 batteries were manufactured under various anode/cathode loading conditions. As the anode/cathode loading ratio increased up to 1.08, the capacity showed an upward trend. Additionally, with an increasing anode/cathode loading ratio, both resistance and output characteristics tended to decrease, leading to an improvement in high-temperature lifespan characteristics. The evaluation of electrical properties based on the anode/cathode loading ratio allowed for the optimization of Li4Ti5O12 battery characteristics during electrode design. The correlation between the anode/cathode loading ratio and Li4Ti5O12 battery characteristics was thoroughly analysed.
