Effect of cathode/anode loading ratio on electrochemical performance of LTO lithium ion battery

초록

To investigate changes in characteristics based on the anode/cathode loading ratio of the Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf> battery, Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf> 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 Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf> battery characteristics during electrode design. The correlation between the anode/cathode loading ratio and Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf> battery characteristics was thoroughly analysed. © 2024, Hanyang University.
