In this study, the electrochemical performance of LiCoO₂ (LCO) cathodes was enhanced by coating them with 0.1, 0.5, and 1wt% titanium dioxide (TiO₂). The dielectric properties of TiO₂ improved the capacity of TiO₂-coated LCO approximately fivefold compared to conventional LCO at a high charge/discharge rate of 10C. This coating also alleviated structural degradation and reduced electrolyte decomposition, thereby enhancing the battery's lifespan and safety. Consequently, TiO₂-coated LCO cathodes demonstrated significantly improved performance over uncoated LCO, making them a promising modification for high-performance lithium-ion batteries. These improvements are crucial for applications requiring both high power output and long-term stability, making TiO₂-coated LCO cathodes a potential candidate for advanced energy storage systems. |
